Safety Guidelines

Before switching on the power, check that the operating voltage listed on the equipment nameplate agrees with the available line voltage.

Any interruption of the grounding conductor inside or outside the equip- ment or loose connection of the grounding conductor can result in a dan- gerous unit. Intentional interruption of the grounding conductor is not permitted.

If it is determined that the equipment cannot be operated safely, it should be taken out of operation and secured against unintentional usage.

To avoid fire hazard, use only a fuse of the correct type, voltage rating and current rating as specified in the parts list for your product. Use of repaired fuses or short-circuiting of the fuse switch is not permitted.

DO NOT open the equipment to perform any adjustments, measure- ments, maintenance, parts replacement or repairs until all power sup- plies have been disconnected.

Only a properly trained technician should work on any equipment with power still applied.

When opening covers or removing parts, exercise extreme care since "live parts or connections can be exposed".

Capacitors in the equipment can retain their charge even after the unit has been disconnected from all power supplies.

Dual Hub Modules

The dual hub modules (designated DataNET ???A??? Hub or DataNET ???B??? Hub) are connected via a serial cross-link cable The wiring of the serial crosslink cable determines which is the ???A??? Hub.

???Wall Mount Unit (Figure 1-6)

???Zone 1 Wall Mount Unit (Figure 1-7)

Advance Communi- cations System

Figure 1-1. Advance Communication System (ACS)

The Advance Communication System (ACS) is a high-speed communi- cations system that uses TCP/IP protocols and addressing to intercon- nect chromatographs and other process analyzers in a common network. Figure 1-1 shows the DNH, Advance Network Access Unit (NAU) and Advance Network Gateway (ANG) connected to the ACS. The NAU con- nects to the ACS and provides a method to access information coming from Advance process analyzers including Advance Maxum and Advance Optichrom GC???s. The ANG is used to connect Siemens Applied Automation???s equipment residing on an Advance Data Hiway to the ACS.

DataNET Hub

Hierarchy

Figure 1-2. DataNET Hub

Hierarchy

A network of DataNET hubs forms a tree-like hierarchy. A DNH may connect to as many as eight ???down-stream??? devices (Maxum Analyzers or Advance Hub Uplink port). Each down-stream DNH, in turn, connects to another eight, and so on. No architectural limit is placed on the depth of the DataNET hub hierarchy. In practice, propagation time considera- tions and hub loading should allow hierarchies at least six or seven lay- ers deep without incurring excessive timing delays.

Ethernet Bridging

Figure 1-3 illustrates two separate trees of DataNET hubs that share an Ethernet segment.

A hub can also connect to-and-from an Ethernet device or an Ethernet compatible Advance Network Gateway (ANG) unit or to and from a non- redundant Ethernet connection. A tree of DataNET hubs can function as an Ethernet bridge, transparently connecting all the Ethernet segments that are attached at any point on the hierarchy. The DataNET hub soft- ware does not implement any software protocols (e.g. IEEE 802.1 span- ning tree) to prevent routing loops. Thus, each tree of DataNET hubs may connect to any Ethernet segment at exactly one point. Multiple Da- taNET trees may share Ethernet links.

DNH Links

Figure 1-4. DNH Links

Figure 1-4 shows the individual links that connect three DataNET hubs and several end devices.

The inter-hub links travel across twisted-pair copper or fiber-optic cables. The link data rate is 2.048Mbps for both cables. The DataNET hub soft- ware auto-detects the type of medium used on each DataNET port, and configures the hub accordingly.

Each connection between a DataNET Hub (DNH) and another device consists of two links. One link connects to the DNH ???A??? Hub, and one link connects to DNH ???B??? Hub. Both links can carry network traffic in normal operation. In the event that one link becomes unusable for any reason, the DNH will transparently and automatically re-route traffic on the re- maining redundant link.

DNH and Maxum Com

Boards

An Advance Network Gateway or Maxum Analyzer that has an Advance Network Communication Board/DataNET (ANCB/DN) can connect to a DataNET hub via any of the eight down-stream ports. The ANCB/DN within these devices functions identically to a DNH.

All wiring shall conform to the National Electrical Code (NEC) and/or other national or local code requirements.

Types of Connections

DNH Power Supply

Each of the DNH electronic modules has a Power Supply Assembly lo- cated below the DataNET Hub board. Each power supply can accept inputs from 85-264 VAC, 47-63 Hz without the need for setting switches or jumpers.

AC INPUT CONNECTOR

Installation Note

Before You Begin

Depending upon the user configuration the power supplies can be con- nected in parallel and powered from a single power source or each sup- ply can be powered from two independent power sources. In either case disconnects must be provided for each input power source.

The DNH should be installed in a rack or wall mount; see Wall or Rack Mounting Installation; page 17. How you route the cable and wire to the DNH is dependent upon the site requirements. See Site Wiring Require- ments (page 19) to determine the requirements for your site.

All wiring shall conform to the National Electrical Code (NEC) and/or other national or local code requirements.

Instructions

1.Shut off the primary AC Power Supply lines to this location.

2.Open the door of the DNH by loosening the four captive screws located on each corner; use a 4mm Allen wrench.

Description

A & B Hubs

The DNH consist of two identical hubs in one enclosure. The left side is usually the DataNET ???A??? Hub and the right side is the DataNET ???B??? Hub. Each hub contains two DataNET Hub boards and power supplies. Figure 2-1 shows the layout of the DataNET Hub board. All port connections are made to the port connectors located on each communication board.

The DataNET ports can accept copper and/or fiber optic cables. In Data Hiway installations the DNH can use the existing Data Hiway cables.

Only the Ethernet port on the ???A??? Hub is active. The cable connection be- tween the two halves determines which is the ???A??? or ???B??? Hub half. See illustration below. A jumper wire visible across pin 1 and pin 2 on the ca- ble connector (J14) indicates that this side is the ???A??? Hub half.

Before You Begin

1.The wiring method (conduit or cable glands) and cable type you use for the installation is dependent upon the site requirements. Review the Site Wiring Requirements. Table 2-1 (page 19) to determine the requirements for your site.

2.Make a block diagram of your existing or proposed network. The block diagram should show all devices and the placement of the DNH. If copper cable is being used, the diagram should show the es- timated cable lengths for each run. This information will be neces- sary in determining if any DataNET Hub Signal Equalizer Boards are required (see page 34).

3.Read through this section to familiarize yourself with port locations, terminal and jumper assignments, and wiring procedures. Refer to Figure 2-1 DNH Communication Board Layout.

DataNET Ports

See Figure 2-1. Each DataNET Hub board has nine DataNET ports. One of the DataNET ports is dedicated to ???uplink??? connections, which will al- ways be to another DNH. The uplink port (Port 9) is an uplink port while the other ports (Port 1 through 8) are downlink ports.

Note that each of the four Downlink Port connectors contains wiring con- nections for two DataNET port channels. The connector row (above the downlink port connectors) marked Port 9 and Port 1 through Port 8 pro- vides single port connector wiring for each of the eight channels. These ports are used for making Fiber Optic connections and/or when using a DataNET Hub Signal Equalizer Board.

Port Connections

To make wiring easier, all board-mounted connectors are equipped with a removable plug wiring connector. Simply loosen the plug???s two top re- cessed captive screws, grasp the connector and pull it straight out from its mating connector.

Loosen the top wire retaining screws on the removed connector. Strip the insulation ?? -inch back from each of the input leads. Insert each lead into the correct terminal. Tighten down each wire retaining screw. Plug the connector back into the board connector and tighten down the two recessed captive screws

Cable Impedance

Settings

Behind each single port connector is an associated jumper pin block, see Figure 2-1. Each block is used to select the termination impedance of its associated port to match the cable???s own impedance characteristics. The three selections for each port are 100-ohm, 120-ohm and 150-ohm. Use the 150-ohm setting for the recommended cable. If the specific cable impedance is not known use the 100 ohm setting. Select the impedance setting that matches the cable impedance by placing the shorting jumper across the selected pins.

+ Important

The Hub Signal Equalizer board balances the attenuation of signals when varying lengths of copper cable connect multiple downlinks from a HUB. The board plugs into a port connector and is wired to its associated downlink port. See DataNET Hub Signal Equalizer Board, page 34 for determining the attenuator board settings.

If you are using a cable other then the recommended cable types, the cable signals for each channel must be measured at the DNH port con- nection. These signal measurements are used to determine the attenu- ator settings for a DataNET Hub Signal Equalizer Board; see page 34.

Refer to Site Wiring Requirements. Table 2-1 (page 19) to determine the requirements for your site.

All downlink connections are made to any of the eight-downlink ports. When a Signal Equalizer board is used the network wiring must connect to TB1 on the signal equalizer board.

Always ensure that the same port number is used for redundant channel connections i.e. Channel A to Port 1 on ???A??? Hub and Channel B to Port 1 on ???B??? hub.

Down Link Wiring with DataNET Hub Signal Equalizer Board

1.Plug the DataNET Hub Signal Equalizer Board into the se- lected Port interface connector.

2.Connect the board???s pig tail leads to the corresponding hub downlink port channel; red lead to (+) terminal, black lead to (-) terminal and white lead to Gnd terminal. See Figure 2-1.

4.If conduit is used the cable shield is only terminated at one end of the cable. If shield is terminated at this end connect it to terminal 3 (GND) on board. If using cable gland connec- tors, cable gland will always connect the shield to the chas- sis.

5.Set the switches on the board to the correct settings; see DataNET Hub Signal Equalizer Board Settings page 34.

Description

Instructions

This section sets the switches on the DataNET Hub Signal Equalizer board. This board is used to equalize the signal amplitude when varying lengths of copper cable are connected to multiple downlink ports on the DNH.

Typically the smallest signal on any DNH port is found on the port with the longest copper cable. Since, Signal Equalizer boards are placed on ports with signal levels greater than 3 dB the port with the longest cable does not require a Signal Equalizer board.

This procedure determines the attenuator switch settings. When cable lengths are unknown, or the cable is other than the recommended cable (Table 2-1), signals must be compared at the Hub to identify which Equalizer board settings are needed. See page 37.

Switch Setting for Unknown Cable Lengths

Switch Settings for Known Cable Lengths

When cable lengths are unknown, or the cable is other than the recom- mended cable (Table 2-1.), signals must be compared at the Hub to identify which Equalizer board settings are needed. See page 37.

If the lengths of copper cable exceed those shown in Table 2-2, follow this procedure. See sample calculations page 36. This procedure will set switches SW1, SW2 and SW3 on the Signal Equalizer Board.

1.Measure and record the longest cable run (in Feet) con- nected from a device to any HUB port. The longest cable run does not require a Hub Signal Equalizer board.

2.Calculate the difference between the longest cable length and the length of cable connected to the port you wish to equalize.

3.Locate the difference in feet in the first column (Feet of Ca- ble) of Table 2-2.

4.Identify the correct Selection range in column two of Table 2-4 and set switches SW3, SW2 and SW1.

Repeat the procedure for each connected port on the Hub 5. except the longest length that does not have an equalizer

board.

Sample Calculations

Calculation One:

Assume connections to Port 1 and Port 2 only.

Port 1 cable = 1000 ft. in length

Port 2 cable = 4000 ft. in length (3000 ft. difference)

Result:

Based on Table 2-2 data,

Port 1 requires compensation for 3000 ft. Selection 4 (2500-3500 feet) Port 2 requires no compensation. Selection 1 (0 dB loss)

Calculation Two:

Assume connections to Port 1, Port 2, and Port 6 Port 6 cable = 5000 feet

Port 1 cable = 1000 ft. (5000 ft. - 1000 ft. = 4000 ft. difference) Port 2 cable = 4000 ft. (5000 ft. - 4000 ft. = 1000 ft. difference)

Result:

Based on Table 2-2 data,

Port 6 requires no compensation. Selection 1 (0 dB loss)

Port 1 requires compensation for 4000 ft. Selection 6 (3500 - 4500) Port 2 requires compensation for 1000 ft. Selection 2 (500 - 1500 ft.)

Note that the lengths of Port 1 and Port 2 cable are the same as in Cal- culation One, however, with the addition of a longer length for Port 6, new settings are required for Port 1 and Port 2.

Before You Begin

Cable Requirements

Signal Measurements

This section is used to set the switches on the DataNET Signal Equalizer Board. If:

???the type copper cable used for port connections is other than the recommended cable

???the length of the cable runs are not known.

Read the section on the DataNET Hub Signal Equalizer Board (page 34) as a prerequisite to this section.

When cable lengths are unknown, or the cable is other than the recom- mended cable (Table 2-1), signal levels must be measured and com- pared to determine the Signal Equalizer board settings.

Signals are compared by measuring the levels at each of the copper ports and then adjusting the Equalizer board settings to within 3 dB of the weakest signal.

If cable lengths are significantly different or if signals differ by greater than ~4 dB, you may have to disconnect the cables on the short lengths to activate the longer cables in order to make a measurement.

View Measurements

Signals are viewed with an oscilloscope.

Scope characteristics: 10 MHz bandwidth capable of measurement sen- sitivity of 0.2 v/div to 1.0 V/div. A typical two-channel scope can be em- ployed using the channel 1 - channel 2 capability. Use X10 probes to reduce the loading of signals.

Option 1.

Connection Point

Option 2. Connection

Point

Connect the two scope probes to the positive and negative terminals of the HUB Communications board, not the Equalizer board, of the channel to be measured. Alternatively, a connection can be made to the leads of the fuses for the selected channel.

???Set time base to ~1 or 2 millisecond per division.

???Observe two sequential signal envelopes of 3-4 millisecond length.

The first signal envelope is the poll from the HUB to the slave device, and the second is the response back from the slave device. The reading from the poll should be ~5 volts p-p. The response may be from ~5 volts p-p (for a short cable with 150 ohm setting) to ~0.75 or 0.8 volts p-p (for a maximum cable length). Responses from a short cable with 100 ohm impedance settings are ~4 volts p-p.

If a large amount of common mode line frequency interference is present the above choice may be unsuitable. In this case, Option 2. is recom- mended.

This option observes the signal across the termination resistor for the selected port.

Using this option, connect the two scope probes across an unused im- pedance jumper location. For instance, if the jumper is in the 120-ohm location, connect the probes on the two pins for the 100-ohm jumper po- sition. A short adapter cable with a two-positioned socket on one end simplifies this connection.

Both channels should be ac-coupled to avoid interference from the 2.5 Volts dc common mode level.

Using this method there is only one reading, the response message, which is seen. Responses may be from ~5 volts p-p (for a short cable with 150 ohm setting) to ~0.75 or 0.8 volts p-p (for maximum cable length). Responses from a short cable with 100 ohm impedance settings are ~4 volts p-p.

Instructions &

Examples

This procedure is for determining the DataNET Signal Equalizer Board settings for other than the recommended cable or if the cable run lengths are unknown.

DataNET Fiber Optic

Coupler

The Fiber Optic Coupler converts between electical signals and optical signals. The conversion is transparent to the network. Fiber Optic signals are impervious to distubances caused by electrical interference from nearby equipment, ground loops, power surges, or a nearby lightning strikes.

A DataNET Fiber Optics Coupler can drive up to 5000 feet of fiber optic cable.

Before You Begin

1.The wiring method (conduit or cable glands) and cable type you use for the installation is dependent upon the site requirements. Review the Site Wiring Requirements (page 19) to determine the require- ments for your site.

2.Refer to Figure 2-1, Communication Board Layout and Figure 2-3. Wiring Diagram and familiarize yourself with the port locations.

The DNH consists of two identical hub modules in one enclosure. The left side is usually the DataNET ???A??? Hub and the right side the DataNET ???B??? Hub. Each hub contains a DataNET Hub board and power supply.

The DNH connects to the Ethernet local area network via the RJ-45 STP connector located on DataNET Hub board. Each of the boards has an Ethernet connection. However, the DNH only the ???A??? hub Ethernet port is active.

HUB ???A???

HUB ???B??????

Active Ethernet Port

Only one Ethernet port is active in the DNH. The wiring connection be- tween the two halves determines which half has the active Ethernet port. A jumper wire visible across pin 1 and pin 2 on the cable connector indi- cates that the side to which it is connected is the active port, which we designate the ???A??? Hub. The hub that has the inactive Ethernet connection is the ???B??? hub.

Remember, only one Ethernet port can be active.

10BASE-T Cable Requirements

1.The 10BASET data cable requires a minimum of two twisted pairs (transmit pair and a receive pair). The type wire used should conform to the AT&T D-inside wire (DWI & PDS), or IBM Type 3, or Category 3 or 5 data grade or equivalent specifications.

2.The maximum length of a 10BASET data cable can not exceed 328 feet (100 meters). Typically to increase the distance each DNH will connect to a hub or other type of repeater/medium converter.

3.The cable should be terminated at both ends with RJ-45 STP male connectors. The table below shows the RJ-45 wiring connections for the DNH end of the cable.

IP Address

How to Assign an IP Address

Table 3-1. Available IP

Addresses

The IP Address consists of a 32-bit number divided into four 8-bit fields. Each field is expressed as a decimal number from 1 to 255 with each field separated by periods. This is referred to as ???dotted decimal??? nota- tion. For example, 192.16.9.52 is an IP address.

Ask your network administrator to assign you an IP Address, or if the DNH will be in a closed plant area and not connected to the Internet you can select an address from Table 3-1.

192.165.0.11

192.165.0.12

192.165.0.13

192.165.0.14

2. Press ??? Enter to complete your entry.

Board Status LEDs

Startup LED Status

During the power-on self-test, all the LEDs will light briefly to indicate that all LEDs and their driving electronics are functioning.

After a normal power-up and a successful self-test, the green (NORMAL) system status LED will light. In the event of a self-test failure, the red (FAULT) system status LED will light, and the yellow (WARN) system status LED will flash an error code. The same indication (red LED on; yellow LED blinking) is used to indicate duplicate IP addresses.

System Status LEDs,

Yellow (WARN) LED

Blink Codes

Continued

The yellow (WARN) blink codes are shown below. The yellow (WARN) status LED will light any time a link error is present. That is, any time at least one red (FAULT) link LED is lit, the yellow status LED will also be lit (green and red LEDs will be off).

Ethernet Port LEDs

Cross Link Status

LED

There are four Ethernet Link Status LEDs.

The cross link status LED is red when no link is established between the two DataNET Hub halves, and is green when a connection is detected. Usually a red indication is caused by the absence of the cross link cable or a faulty connection.

Configuration

Conflicts

Cabling errors:

Example

NOTE

The DNH port green LED is off, or intermittently flashes between green and red. This can indicate a configuration conflict caused by a faulty ca- ble or a wrong connection or improper configuration parameters.

1.Inspect all cable and connectors for damage.

2.Verify that the cable is connected to the correct Hub half and correct Port.

3.Verify that the Channel ???A??? link is connected to the ???A??? Hub half and that the Channel ???B??? link is connected to the ???B??? Hub half.

4.Verify that both Channels A & B use the same port number on their respective Hub half.

5.Display the Port Status screen by connecting a PC to the Configura- tion Port, logging in, and then typing display links. Verify that all Ports are connected as expected; see example below.

The following example shows that Port 1 on the B Hub is incorrectly con- nected to Port 1 Channel A, on device 172.16.99.7.

Signal Quality

Problems

Instructions

If a DNH port green LED is off, or intermittently flashes between green and red the signal levels for that port are either too high or low relative to the other Hub ports.

If a port link fails to connect at all, the port can be set to a test mode The test mode will cause port activity to occur approximately every 50 milli- seconds instead of approximately every 7 seconds as it would for an un- connected link. While in the test mode the signal for that port can be measured.

1.Connect a standard 9-pin COM cable from the designated PC COM port (see page 49, step 7.) to the Configuration Port on the hub half containing the port in question.

2.Open HyperTerminal program on your PC; reference Configuring Your PC, page 49.

3.Connect and Log on to the DNH.

Description

Unique Commands

This chapter is intended for maintenance personnel.

This chapter provides definitions for all of the commands you will be us- ing for setup purposes or for performing test diagnostics.

These are the commands that are unique to the Advance DataNET Hub.

???config address ip??? command

???config device id??? Command

This command configures the hub-half IP address. Each individual hub board (???hub-half???) in the system must have a unique IP address. Your network administrator can help you choose appropriate addresses for your DataNET hubs. IP addresses are entered in ???dotted-decimal??? nota- tion. For example:

config address ip 192.10.6.123

The IP address is automatically stored in the hub-half???s non-volatile memory when you enter this command. You can display the current IP address with the config display command.

Each pair of hub boards shares a common ???device ID.??? This ID must be configured into each board???s non-volatile memory at installation time with the config device id command. Device Ids have the same form as IP addresses (i.e., four dotted-decimal components, in the range 0 through 255). Any value may be chosen for device IDs. The only requirements are that each pair of hub boards that make up a complete hub, share the same device ID and that device IDs are not duplicated between any hubs in a single DataNET.

One convenient convention for assigning device IDs is to use the IP ad- dress of the ???A??? half of each pair as the device ID.

???config display??? Command

???config netmask??? Command

This command displays the settings for the hub???s non-volatile configura- tion parameters.

This command sets the IP subnet mask for a hub-half. Your network ad- ministrator can help you choose an appropriate subnet mask for your DataNET hubs (subnet masks are not always required). Subnet masks are entered in ???dotted-decimal??? notation. For example:

config netmask 255.255.192.0

The subnet mask is automatically stored in the hub-half???s non-volatile memory when you enter this command. You can display the current sub- net mask with the config display command.

???config iproute??? Command

???config timeserver??? Command

???date??? Command

This command sets the address of the IP router to which the hub-half should send IP messages whose destinations do not reside on the hub???s own network. Your network administrator can help you choose appropri- ate router addresses for your DataNET hubs (a router address is not al- ways required). Addresses are entered in ???dotted-decimal??? notation. For example:

config iproute 192.10.6.1

The router address is automatically stored in the hub-half???s non-volatile memory when you enter this command. You can display the current router address with the config display command.

DataNET hubs may be configured to request time and date information from a DataNET time server. To do this, enter the non-zero IP address of the time server with this command. When so configured, each time the hub powers up or resets, and every 24 hours thereafter, it will request the current local time and data from the designated time server. The command has the following form:

config timeserver 192.10.6.2

When a hub receives a reply to a time server request, it will update its local clock with the received time. Note that hub boards include their own non-volatile clock. Thus, if a hub board loses contact with the time server, it will maintain its own time and date, even across resets of power cycles.

A hub???s time and date may also be manually configured (see date com- mand below).

Without an input argument, date displays the current date and time, as known by the hub-half. Otherwise, date sets the hub-half???s current date and time according to the input argument. The date command has the following form:

date yyyymmddhhmm

The argument part yyyy is the four digits of the year; the first mm is the month number; dd is the day number in the month; hh is the hour num- ber (24 hour system); the second mm is the minute number; and .ss (op- tional) specifies seconds.

For example, to set the date to Oct 8, 12:45 AM, type

date 199810080045

???del??? Command

???display??? Command

This command deletes selected items from the hub???s Source Address Table (SAT). The command offers options to delete all entries or se- lected entries by IP address or by MAC address. The command syntax is as follows:

del xx:xx:xx:xx:xx:xx or del xxx.xxx.xxx.xxx

where xx:xx:xx:xx:xx:xx is a MAC address in colon-separated hexadeci- mal format, and xxx.xxx.xxx.xxx is a dotted-decimal IP address. Note that in both cases, leading zeros must be included in the addresses. That is, if the IP address of an entry is ???192.1.2.3,??? the address must be en- tered as ???192.001.002.003.??? If the designated address is not found in the SAT, the hub-half displays an error message:

Address xx:xx:xx:xx:xx:xx not found or Address xxx.xxx.xxx.xxx not found

If the deletion is successful, the hub-half confirms it with a message:

Address xx:xx:xx:xx:xx:xx deleted or Address xxx.xxx.xxx.xxx deleted

The entire SAT may be cleared with the command:

del all

Note that the SAT always contains one entry that may not be deleted, for the hub-half itself.

Display the Source Address Table (SAT). This displays the MAC ad- dresses of all stations known to the hub-half. IP addresses are also shown for all stations whose IP addresses the hub-half has learned. The list is sorted by IP address; entries that do not include an IP address are listed following those that do. The port through which the station is reached is displayed in the right-hand column. This generates a display similar to the following:

???display links??? Command

This command displays the hub-half???s link state table. The link state table indicates, for each link, whether or not the link is currently ???connected,??? ???unconnected,??? or undergoing link validation (???validation???). For DataNET links (including the cross-link), the table also gives the device to which the link connects. DataNET devices are identified by their device IDs.

Example: local> display links 3

???download??? Command

If a hub port is connected to an Advance Network Gateway with Data- NET the display link command will also provide enhanced configuration information when the link number is specified

Use this command to load new firmware into the hub-half via the RS-232 Configuration port. The procedure for firmware download is:

1.Make sure you have a ???hub_rom.mot??? file available for download.

2.Log into the target Hub through the Configuration port, using Hyper- Term.

3.Type ???download??? at the hub???s prompt (???>???). The hub will then prompt to begin transmitting the download file.

4.Transmit the download file. Use the HyperTerm ???Transfer --> Send Text File?????? command. Find the ???hub_rom.hex??? file using the browser window. You may have to select ???Show all files??? in the ???Files of type??? window to see the ???hub_rom.mot??? file.

???events??? Command

???dn??? Command

5.After you have selected the ???hub_rom.mot??? file and click on ???OK,??? HyperTerm will begin transmitting records to the Hub. The Hub will respond by periodically displaying addresses as the file downloads.

6.After approximately 5 minutes, the download will be complete. The hub will display messages indicating that the download has com- pleted, and it is erasing and programming the FLASH memory.

7.Finally, the Hub will reset, and display a new login prompt.

This command controls logging of hub software events. Software events mark the progress of the Hub software in some detail so board problems may be more easily analyzed. The events off command will stop the logging of event messages. The list command, as described above, is used to view the software events in the event buffer.

This command may be used to override default values for several pa- rameters related to the HDLC protocol used by DataNET. Specific forms of the command are:

dn window

dn window num

dn polldelay

dn polldelay time

dn portdelay

Displays the transmit ???window??? for the HDLC protocol used by DataNET. This is the number of I-frames that a station may send before it must receive an acknowl- edgment from the receiving station.

Sets the transmit window used by all ports on the hub. The parameter ???num??? must be a number 1 through 7. The de- fault window size is 7. The hub does not store the window size parameter in non- volatile memory, so non-default values will be lost after a reset.

The ???poll delay??? parameter applies only to ports 1-8 on a hub. It controls the time a hub will wait between polls of any port. As soon as a hub finishes an exchange of messages on one port, it will normally advance immediately to the next ???con- nected??? port and begin the next ex- change of messages. If ???poll delay??? is set to a non-zero value, the hub will enforce a delay before each new exchange be- gins. The ???poll delay??? is given in millisec- onds and defaults to zero (no delay).

Sets the poll delay to the value given, in milliseconds. Actual times are rounded down to the nearest ten milliseconds.

This parameter gives the delay, in milli- seconds, that a hub will enforce between message exchanges with a particular slave device. That is, before initiating a poll to a slave device, the hub will make sure that at least this much time has elapsed since the last poll to the same device. This keeps a hub from consum- ing all of the slave device???s processing time by continuously polling it at short intervals. This parameter defaults to 50 milliseconds.

???help??? Command

???list??? Command

This command generates a simple list of available commands.

Enter the list command at any time from the Configuration Management interface to see event buffer messages. The list command has an inter- nal current sequence number that is set to 1 each time a Configuration Management login occurs. The list command will show 21 messages each time it is entered, beginning with the current sequence number. The current sequence number is updated each time list is used. A new cur- rent sequence number can be entered with the list command:

???login??? Command

The event display gives a time-stamp, and an event description. All events other than frame-capture events are always shown as single lines. Captured frames may be summarized as single lines, or expanded into a multi-line display (see ???validation timeout??? command).

The user can view more than 21 messages by supplying a sequence number and list length:

The list length may appear by itself:

list ,32

This command lists the next 32 trace buffer entries, and increments the current message number by 32.

All the messages in the internal trace buffer can be viewed by listing se- quence number one then entering the list command until the last mes- sage is displayed. When the current message number is incremented to the last message in the internal buffer, it is automatically set to 1. You can list all the messages in the buffer without pausing between mes- sages with list 1,300.

There is a continuous listing mode for monitoring all the messages in the internal trace buffer. Start continuous list mode by entering list on. All the messages in the internal buffer will be displayed and any new mes- sages will be listed as soon as they are collected into the buffer. Termi- nate the continuous listing mode by entering a Control-C key combina- tion.

To clear all events from the event buffer, use

list clear

This command logs the user onto the hub-half and gives the user per- mission to access, display, and configure the hub-half. The format for the login is a minimum 5-character/maximum 20-character alphanumeric password. The user can login to a remote device by typing the IP ad- dress of the remote device after the login and password parameter. Ex- ample: login password 172.16.9.12

???logout??? Command

???netstat??? Command

This command logs the user out of a session. The user must be logged out of the local device to login to a remote device.

This command may be used to display statistics for the DataNET sec- tion. If a link number is given, statistics are displayed for just that link. If no link number is given, summary statistics for all DataNET links are given. If the keyword ???clear??? is given, the statistics counters are reset to zero:

netstat dn [link] [clear]

???port??? Command

This command will enable or disable normal DataNET communication on individual ports. Before placing a port into ???test??? mode (see test com- mand below), the port must first be taken offline with:

port stop num

where num is a port number, 1 through 9.

This command may also be used to reset a port that has been automati- cally taken out of service by the hub after detection of a DataNET topol- ogy loop:

port start num

This will re-start normal DataNET communications on a port.

???test??? Command

???timeout??? Command

This command places a selected port into a hardware diagnostic mode. The command

test 4

places port 4 into test mode. The hub will generate poll messages on port 4. All other ports continue to operate normally. The command

test off

turns off test mode. Only one port at a time may be in test mode.

This command may be used to disable the user login timeout. Normally, if a user has not issued a CLI command for five minutes, the hub-half will automatically shut down the user???s login session. This command may be used to defeat (and re-enable) this timeout:

???trace??? Command

The trace command controls the hub???s frame tracing function. This fea- ture captures network messages sent and received by the hub-half in that hub-half???s event buffer. The trace command controls which mes- sages are captured in the event buffer.

Trace messages may be collected for the Ethernet port, the cross-link port, any of the 8 downstream ports or the single upstream port. Trace data may be filtered to collect only input frames, output frames, or data frames (excluding protocol-only frames such as poll/acknowledge). The hub will not capture any frames until the ???trace on??? command is given.

Before issuing ???trace on,??? the user can set up trace filtering as described below. By default, tracing is set up for all frames on the Ethernet port.

To set up tracing, the trace command is followed by a list of ports and a filter mode. The port list is a comma-separated list, which may include any of:

The port and filter options may be commanded separately or combined into a single command:

trace ethernet all

sets up tracing for all frames on the Ethernet link.

???validation timeout??? Command

sets up tracing on downstream port 2, for input data only.

trace crosslink output

sets up tracing of frames sent on the cross-link.

The filter may also specify frames for a specific station by declaring an IP address. The station filter cannot be combined with the port specifica- tion in a single command. To collect data from or to a station the com- mands would look like:

trace 9

trace 172.16.9.201

trace on

The first command specifies the upstream port for trace data. The sec- ond command filters the trace data to a single station???s frames, and the third command enables tracing.

Finally, the trace parameters may be reset to their default values (tracing all frames on the Ethernet port, without any address filtering) with:

trace reset

This command sets the time, in seconds, that the hub-half will wait for the ???link validation??? diagnostics to complete.
