1. INTRODUCTION

The purpose of this documentation is to describe the function and opera- tion of the Model 6401B Field Test Unit in conjunction with UNIDATA???s Portable Data Logger. This document is aimed at the inexperienced user who is unfamiliar with the Field Test Unit (FTU).

The Portable Data Logger and Field Test Unit act as a team for the collec-

The Portable Data Logger (PDL) is a microprocessor based device designed to have a battery lifetime of over 2 years. This allows the logger to remain in the fields for long periods of time for the recording of data. The data is recorded in CMOS RAM memory which is available in 8K to 64K capacities. The logger provides analogue and digital inputs for data sam- pling, and internal logger programs and crystal clock for the recording of data in the logger???s memory.

1.1.1 Memory structure

The memory of the logger is divided into 256 byte Blocks (e.g. a 24K logger will have 96 blocks, and a 64k logger has 256 blocks). Hence, any particular location in the logger???s memory can be referred to in two ways: either by its absolute location in memory, or by its block and location within that block (e.g. absolute location 0 is also block 0 location 0; absolute location 1023 is block 3 location 255).

Field Test Unit Software

Blocks 4 onwards (location 1024 to the end of memory) are reserved for logger data storage. Bytes are logged sequentially, without gaps, and the number of bytes logged per log interval will depend on the PDL program.

1.2 FIELD TEST UNIT

The Field Test Unit (FTU) is a battery powered, Intel 8085 based microcomputer with resident Microsoft BASIC (20K ROM). Memory capacities of 8K or 16K RAM are available for program and data storage. RAM memory is divided between a text area and a file area. The text area is used for loading and executing BASIC programs. The file area is used to store Program and Data files. Files in the file area are called RAM files.

1.2.1 Why use a FTU?

The Field Test Unit allows the programming and interrogation of the data loggers in the field. The FTU can be used to :

??? Display and alter channels, accumulators, and memory locations in the data logger.

???Unload the logger into a RAM fiIe or onto cassette.

???Load the logger with new programs from a RAM file or from cassette.

???Transfer logger data and programs between the FTU, cassette, and a host computer.

1.2.2Installation

The FTU should come with the following:

???Programming Guide for Beginners

???Reference Card (for X-07)

Field Test Unit Software

???Batteries (AA x 4)

???Model 6602E cable to connect FTU to Data Logger

???Model 6401D Mains Power Pack

???Prom with STARLOG Software (already installed)

???Reference Card for (FTU)

1.2.3Switching on the FTU

Ensure that the batteries have been inserted and that the Lock Switch (slide switch, underneath) is in the ON position, then press the ON/BREAK key. The FTU should power on and the following appear on the screen :

Copyright(c) 1983 by Microsoft & Canon 14940 Bytes free

Note, however, that the number of Bytes free may differ from the above as it depends on the size of the file area that has been set (the size of the file area can be changed)

1.2.4 Running a Program

To run a program, use the BASIC command :

RUN"filnam"

where filnam is the name of the file you wish to run.

1.3 CASSETTE STORAGE

Cassettes may be used for long term storage of Programs and data. It is ad- visable to keep a copy of programs on cassette, as the contents of the file area may sometimes be destroyed.

1.3.1 Attaching the cassette

The cassette cable plugs into the small round DIN-type socket on the right hand side of the FTU. The other end of the cable has three pIugs. These should be plugged into the cassette recorder as follows:

1.3.2 Saving a Program

To save a program on cassette, rewind the cassette to a blank section, then put the cassette recorder into RECORD.

To save a program that is in the file area type :

CSAVE???filnam???

Where filnam is the file name you wish the program to be saved under. It is usually good practice to save the program twice (on the same cassette), as a protection against corruption on the tape.

To save a program that is in the file area, first load it into the text area by using the LOAD command :

LOAD???filnam???

then save it on cassette as above.

1.3.3 Loading a Program

To load a program from cassette, rewind the cassette to the start of the file, then put the cassette recorder into PLAY, then type:

CLOAD???filnam???

Where filnam is the file name of the program you wish to load. If the file name is left out, then the next program on the tape will be loaded.

To save the program in the file area use the command :

SAVE???filnam???

Field Test Unit Software

2. GETTING STARTED

The STARLOG FTU Software Package Model 6302A consists of a cassette tape, a memory chip (6264LP) and this manual.

2.1 PROGRAMS

The Field Test Unit (FTU) (Canon X-07) is usually delivered complete with the ???FTU??? prom loaded and ready to use.

2.1.1 Filename Extensions

Files saved in the FTU RAM directory will have the following file exten- sions:-

2.2 FTU MEMORY GUIDE

The Field Test Unit comes complete with a 16k RAM which is sufficient to operate all UNIDATA supplied software. The FTU RAM may be ex- panded to 24k with an 8k memory card.

Field Test Unit Software

To use the 8k 6264LP RAM supplied to increase the FTU memory to 16k switch the FTU off and remove the cover of the chip socket on the back of the FTU.

Replace the FTU ROM with the RAM chip and change the memory select switch from ROM to RAM. Replace the cover press the reset button on the back of the FTU and switch on.

2.3 FTU INITIALIZATION

If for any reason the FTU programs need to be loaded, the following proce- dure should be used:-

1.Using a pencil, press the RESET button at the rear of the FTU. (This is a Master Reset, so ALL PROGRAMS WILL BE LOST).

2.Connect FTU to Cassette Recorder with Model 6302A

software cassette tape inserted/rewound and ready to use.

3. Press ON/BREAK key on the FTU. The message ???14940 Bytes free??? will appear. (Note: at least 14940 Bytes are re- quired to operate this software, more ???free??? bytes are fme).

4. Type:- FSET 10000 Return (2300 if using PLOT/PLOTX)

5.Type:- CLOAD ???FTUC??? Return (system should respond with ???Found FTUC??? and then continue to read the program FTUC from the cassette tape and store it in the FTU)

6.Type:- SAVE ???FTUC??? Return (to save the program FTUC permanently in the FTU???s RAM file area.) SAVE ???LOAD/UNLOAD???

7.Repeat Steps 5 & 6 above to Load & Save programs ???LOAD??? and ???COPY???. Program ???PLOT??? may also be loaded if there is sufficient RAM in the FTU [in this case, ???PLOT??? should be LOAD(ed) and SAVE(ed) first, then ???FTUC???, ???LOAD??? and ???COPY???).

Field Test Unit Software

8. Type:- NEW then press Return

All FTU programs are now loaded and ready to use.

9.Type:- RUN ???FTUC??? then press Return

(To begin FTUC operating. Press BREAK key then RUN ???LOAD??? or RUN ???COPY??? to begin those programs)

2.4 LOADING ???PLOT??? IN 16K RAM FTU

The Model 6302A Software Support (Version V#5.0 or later) requires a 16k memory FTU (Canon X-07), therefore only the Print/Plot Package can be loaded into the FTU If the FTU has been expanded to 24k, then other FTU utilities may also be loaded and the Print/Plot Package may be saved as a RAM file in the FTU.

To load program ???PLOT??? (the Print/Plot Package):-

1. DELETE all RAM files in the FTU (or perform Step 1. above).

2. Connect cassette player (Step 2. above) and insert tape, side B.

3. Type:- FSET 2300 then press Return

4. Type:- CLOAD ???PLOT??? then press Return

(The system should respond with ???Found:PLOT??? and con- tinue to load the program into the FTU)

Note:- don???t save ???PLOT??? in the RAM file area (in a 16k FTU).

5. Type:- RUN then press Return

(To begin execution of the Print/Plot package).

Field Test Unit Software

3. (UN)LOAD, PLOT & COPY

The Model 6302A Software Support Package (Version V#5.0 or later) (Un)load/Plot/Copy allows information to be unloaded from a Data Logger and printed or plotted on a printer/plotter (Canon X-710) attached to the Field Test Unit (Canon X-07). In print mode, any standard 80 column printer may be used when interfaced to the FTU via the ???Centronics??? printer interface or RS-232 communications interface.

In addition, program and data files may be transferred between cassette, RAM, Data Logger and a host computer in various formats.

3.1 STANDARD FEATURES

a)unload a Data Logger and store the resulting data in a RAM file

(requires 24k) or a cassette file on a datacassette tape.

b)load a logger program from a RAM file or a cassette file into a Data Logger.

c)print the contents of an unloaded Data Logger direct or from a

d)plot the contents of a Data Logger direct or from a RAM file or a cassette file in a four color multi-plot format (up to 8 chan-

nels/fields per plot) onto a Canon X-710 printer/plotter.

e)transfer unloaded information or logger programs between a host computer and the FTU in ASCII format via an RS-232 com-

munication channel.(see Appendix A for message format).

f)transfer unloaded information or logger programs between an IBM-PC type system and the FTU in LOGGER message for- mat. (using the IBM-PC utility program ???PDLIO???). Print or plot logger files direct from an IBM-PC type system (using the PDLIO utility program).

NOTE: The IBM-PC utility program PDLIO is not part of the (Un)load/Plot/Copy Software Package. Program PDLIO is included within the STARLOG Software Support Package for the IBM-PC (and

Field Test Unit Software

compatibles). If you require to use PDLIO you must purchase that package separately.

g)copy data files and command files between cassette, RAM and the

3.2 COMMAND FILES

Once the format of the (un)load or print/plot output has been decided, the operator commands (entered into the keyboard in response to the questions listed below) may be saved in a RAM file or on cassette.

This feature saves the operator entering all the responses every time a plot or unload is performed. Instead, the operator simply enters in the command file name and the (un)load or print/plot proceeds automatically using the pre-saved operator commands from that command file.

3.3 COPY(ING) FILES

The ???COPY??? program allows data files or command files to be transferred to/from RAM/cassette or to/from FTU and a host computer. These files must be standard BASIC files in ASCII format (lines terminated with a car- riage return and less than 255 characters in length).

3.3.1 Running COPY

1. Connect datacassette and/or RS-232 link to FTU

2. Type:- RUN ???COPY??? then press Return

3. Answer the following questions:

Field Test Unit Software

The above two questions are repeated for the OUTPUT file.

Baud Rate?You have selected Xfr mode. Maximum Baud rate is 8000. (use 8000/4800/2400/ 1200/300) Note: if cassette selected Baud Rate is not asked for.

3.3.3 Timing considerations

When copying a file from a host computer (via the RS-232 communications channel) to a RAM file in the FTU, a delay of two (2) seconds must be provided by the host computer after sending each line before the next line of the fiIe is sent to the FTU. This delay must be increased to thirty (30) seconds per line when the FTU is storing the file on a data cassette.

NOTE: The transfer to/from a host computer is terminated by the last line containing the termination word END followed by a carriage return. (i.e.???END??? then press Return)

3.4 (UN)LOADING TO CASSETTE/RAM

Either program ???PLOT??? or program ???LOAD??? may be used to unload data from a Data Logger.

???PLOT??? contains all the features of ???LOAD??? but ???PLOT??? (un)loading is slower and requires a larger amount of RAM (memory).

5. DATA STORAGE FORMAT

Data storage and communications to/from RAM, Cassette tape and RS-232 communication with a host computer conforms to the format detailed below.

5.1 FTU FILE FORMAT

The data file consists of three parts, one HEADER message (Line 1:) one or more DATA messages (Line 2: onwards) and an END message line.

1END message which terminates the file.

5.1.1HEADER Message Format

The HEADER information is used to describe the file and its contents, Fields are separated by commas. (The message is terminated with a C/R L/F sequence.)

HEADER message - Line 1:-

Field Test Unit Software

5.1.2 DATA Message Format

There are one or more DATA messages used to store a data file. The for- mat of the DATA message is designed to be generated by a BASIC ???PRINT??? statement and read by a BASIC ???INPUT??? statement.

DATA messages - Line 2: onwards

data C/R L/F

data = up to 252 characters coded in Hexadecimal (2 characters per data logger byte). The characters are sent high order 4 bits followed by low order 4 bits such that the following BASIC instructions would have VALUE as the first data logger byte in the ASCII DATA message (STRING$)

VALUE = VAL ("&H" + LEFT$(STRING$,2))

5.1.3 END Message Format

A single line is used to terminate the data file.

END message -

END C/R L/F

5.2 HOST COMPUTER PROGRAM TO RECEIVE DATA

The following sample BASIC program will save the information sent by the COPY program via the RS-232 communications link. The sample program is written for an IBM-PC type system, however a similar program will operate on any computer.

6. NFTU COMMANDS

The program NFTU is a simple Field Test Unit program which will com- municate with the Model 6003 Data Logger and display (or alter) the Data Logger memory contents.

This Software Package is unsupported by UNIDATA. This means that the software is supplied ???as is??? and UNIDATA does not intend to correct any errors or make further improvements to the package.

Memory location may be displayed as groups of 4 single bytes or as a 32 bit integer number.

6.1 OPERATION

1. Turn the FTU on using the ???on/break??? key.

2.Plug the FTU 25 pin D type connector into the data logger computer connector.

3. The FTU will display the value of the cycle counter (location 4)

4.Press a key L, B, P, ASDF or a ???space??? and wait for a prompt.

5.When finished, remove the FTU plug and turn the power off using the ???off key.

6.1.1L COMMAND

The L command allows you to enter a number from 0 to 255 and view that byte LOCATION in the current block. The display is reset to ???byte mode???.

6.1.2 B COMMAND

The B command allows you to enter a number from 0 to 255 and shift to that BLOCK of memory for display or alteration. The display is reset to ???byte mode???.

Field Test Unit Software

6.1.3 P COMMAND

The P command allows you to PUT new data to memory. Only one byte location may be altered at a time. The location altered is the first byte dis- played (the one indicated by the status line). The new value must be between 0 and 255. Use the ???S & D??? keys to step backwards and forwards to adjacent locations to be altered.

6.1.4 CURSOR KEY COMMANDS

The Cursor Keypad (at the top right of the FTU keyboard) step the dis- played location backwards (or forwards) one byte using the & - command keys, and backwards (or forwards) four bytes using the ^ & Vcommand keys.

6.1.5 ???space??? COMMAND

The ???space??? bar toggles the display between ???byte mode??? (4 individual byte display) and ???integer mode??? (4 byte, 32 bit single integer).

6.2 INITIALlZATlON

The initialization sequence should be avoided if possible. The FTU will in-

with the power pack inserted so as the memory does not lose power. However if the program contained in the FTU has been lost, perform the following sequence.

(<RET > in the following sequence is the lower right hand key marked ???RETURN??? and $ is the dollar sign appearing above the 4)

Type in the program appearing at the end of the Section Enter ???START$ = ???RUN??? + CHR$(l3)

Enter ???OFF1 <RET > ???\

The field test unit will power down and when next press the on button the FTU should appear as normal.

The following is a table of addresses versus channel viewed on the Field Test unit.

7. FTUC COMMANDS

7.1 DISPLAY FORMAT

The display of the FTU has three formats available. These formats can be selected at the touch of a button. Normally as many bytes as possible are dis- played on the screen at all times. For example - if you were displaying the contents of the logger memory as single bytes then four bytes could be dis- played per screen line, making a total of eight bytes displayed (only the top two lines of the display are used for display purposes).

The three formats available are:

7.2 DISPLAY OF THE LOGGERS CURRENT MEMORY VALUES

In this format the values are not scaled and as displayed as a number from O-255. Eight values are displayed across the screen and they represent the current selected memory address location followed by the successive seven memory locations. The current memory location can be changed using keystrokes outlined later. This display format is the default when the FTU is first powered up and the logger connected.

EXAMPLE: When first powered up and connected the FTU will display the following (or similar):

10300 x 4 4 0 0

Address = 0

The ???10??? is the version of logger connected. (Memory location 0)

The ???3??? is the runtime of the program in the logger. (Memory location 1)

The ???0???s??? are memory locations not used.

The ???X??? represents a value that will change on your screen. This is Memory Location 4 and is where the logger shows the current clock value.

The ???44??? is also a changing value and is related to your loggers clock value (Memory Location 6) [See Hardware Supplement 6200 for further details of the logger???s memory locations].

Field Test Unit Software

7.3 USER DEFINED SCREEN FORMAT

This screen format allows the user to set up and save a custom designed for- mat for a specific application. This routine is initialised by pressing the "E" key. The FTU will then prompt the user to enter in:

Select the appropriate formula for your application from the list below

If formulas RYVS have been selected then the FTU will respond with a prompt for the user to enter the value of the reference resistor used with the transducer.

If the formulas FH have been selected then the FTU will prompt with a line ???Min value????. The minimum desired vaIue for the scaling should then be

Field Test Unit Software

entered. The FTU will then prompt with ???Max Value????. The maximum desired value for the scaling should then be entered. The FTU will now only display values from the minimum to maximum for the selected memory loca- tion/s.

After responding to the above prompts the FTU will prompt

???Using #####???

This is a feature that enables the FTU to custom format the decimal struc- ture and units for the displayed value.

EXAMPLE:

By typing the following to the USING prompt

???##.# Celsius???

The FTU will display the memory value in the format

???34.4 Celsius???

If the screen is cleared beforehand, (SHIFT-HOME), this will be the only information displayed by the FTU.

For further information on ???PRINT USING??? see the Canon X-07 ???Basic Reference Manual??? page 92.

7.4 MEMORY ADDRESSING

There are three ways to address memory within the logger using FTU- PROM:

Block number

Location from start of current Block

Absolute address

7.5 CURSOR KEYPAD

Using the direction keys, the display may be shifted forward and backward by one value, or by a given screen step. The screen step (STEPSIZE) is

The default STEPSIZE can be set by pressing ???S???. The FTU will then respond ???Step size???? . The entered number will be the resultant number of

This step size can be saved in a screen format file.

The SPACEBAR will reset the screen to its initial state.

7.6 SCREEN FORMAT FILES

The FTU-PROM has a feature that allows a custom designed screen format file. After designing a screen format using the ???E??? key the screen can be saved by pressing the ???W??? (write) key. The FTU will then prompt for a file name. After obtaining the file name the FTU will save the screen format and resume working. 350 Bytes of RAM are required for each screen set up. The screen formats and remaining memory can be viewed by pressing ???F???. To load in a new screen format press ???R??? followed by the filename of the desired screen format.

Warning: Use of a filename containing the letters ???FTU??? may cause the FTU to lock up on power on.

7.7 COMMANDS TO MODIFY DATA LOGGER

The FTU-PROM has the ability to display and modify the data loggers memory. The appropriate commands and their functions are:

7.7.1 ???P??? - Put

This command allows the user to change the values of the loggers RAM memory. Up to eight values can be changed at one command by typing con- secutive values separated by comma???s.

EXAMPLE:

7.7.2 ???T??? - TIME

This command enables the user to check and/or reset the logger???s time and date. The Canon X-07???s date and time MUST be set accurately for this pro- cedure. If the Canon???s time/date needs to be changed type ???t??? to reset it, (see below under X-07 Commands).

Press Return or Put

If the date on the logger side is as desired then press RETURN to exit. If not the press Put - ???P??? to set the logger???s date to that of the Canon.

7.7.3 ???d??? - DISPLAY *

This command causes the FTU to display current information from the log- ger on:

???Cycle time of the logger

???Log size (number of bytes used per log)

??? Log interval in minutes and seconds

??? Time of the first log, the number of logs made and the number of full days the logger has been recording

EXAMPLE:

Press shift-D (???d???) FTU display responds: 1 second logger

1 byte log size

1 min 0 second log interval First log at

12:09:00 87/05/29 3 logs 0 days press RETURN

7.7.4 ???r??? - RESET *

This command resets the logger data storage to an original state. All data is lost and the logger starts logging immediately.

By pressing ???a??? the user can interchange the bottom line from an address dis- play to that of the loggers time reading at each specific log. If the screen is cleared and set up prior to entering ???j??? then the FTU will display the logged data in actual units rather than raw bytes.

7.7.6 ???D??? - DATA

This command will cause the FTU to prompt ???Data Buffer (0-7)???. After receiving the desired buffer number the FTU will then display information on that buffer pointer from the logger.

7.7.7 ???J??? - JUMP to ADDRESS

Jump to address pointed to by the start, end or current pointer, (this infor- mation can be displayed by the above command). The user will be required to enter in the desired buffer number (0-7). The user can select the current, end or start buffer by pressing ???S???-start, ???E???-end or ???C???-current.
