Usage Notice

Please read before you start to use the GPS receiver:

??GPS(Global Position System) is found and operated by US Department of defense. The Organization is responsible for accuracy and maintenance of the system with full authority. Any change that is made by the organization will affect accuracy and function of GPS.

??For your driving security, we strongly suggest that you do not operate the device during driving.

??When satellite is navigating, if you are inside a building, tunnel or near huge blocks, it will affect GPS satellite signal receiving. At this time, this device probably dose not have positioning capability.

??If you have a speed alarm in your car, the signal receiving of this device will be interfered. If this situation happens, please stop using your speed alarm.

??The receiver operating temperature is located between -10???~70???.For safety and lifetime of Li- ion battery usage, do not place this device over two hours with overheated environment.

1.Introduction

1.1 Introduction

G-Mouse MR is a total solution GPS receiver (G-MR instead below), designed based on most high sensitivity MediaTek kernel architecture. This positioning application meets strict needs such as car navigation, mapping, surveying, security, agriculture and so on. Only clear view of sky and certain power supply are necessary to the unit. It communicates with other electronic utilities via compatible dual-channel through RS-232 or TTL and saves critical satellite data by built???in backup memory. With low power consumption, the G-Mouse tracks up to 32 satellites at a time, re-acquires satellite signals in 1 sec and updates position data every second. 4 power-saving mode allows the unit operates with ultra low power request.

1.2 Features

G-MR provides a host of features that make it easy for integration and use.

1.Use the most advantage GPS module (MediaTek), the module got high performance CPU inside(ARM CPU), allow users to design different applications, store in the module, to provide the

most economic solution for anybody.

2.High performance receiver tracks up to 32 satellites while providing first fast fix and low power consumption.

3.Compact design ideal for applications with minimal space.

4.A rechargeable battery sustains internal clock and memory. The battery is recharged during normal operation.

5.Auto switch-able power saving mode 1~4, reduce your power exhaust.

6.User initialization is not required.

7.Dual communication channels and user selectable baud rates allow maximum interface capability

and flexibility.

8.Optional communication levels, RS-232 and TTL meet ordinary application and new fashions of connecting PDA with TTL or RS -232 output.

9.FLASH based program memory: New software revisions upgradeable through serial interface.

10.LED display status: The LED provides users visible positioning status. LED "Blinking" when

power connected and "On" when G-Mouse got positioned. 11. Industry level water proof design for all weather.

2.Operational Characteristics

2.1 Initialization Setup

After the initial self-test is complete, the G-MR will begin the process of satellite acquisition and tracking. The acquisition process is fully automatic and, under normal circumstances, will take approximately 37 seconds to achieve a position fix (36 seconds if ephemeris data is know). After a position fix has been calculated, valid po sition and time information will be transmitted over the output channel(s).

The G-MR utilizes initial data such as last stored position, data and time as well as satellite orbital data to achieve maximum acquisition performance. If significant inaccuracy exists in the initial data, or if the orbital data is obsolete, it may take a long time to achieve a navigation solution. The G-MR Auto- locate feature is capable of automatically determining a navigation solution without intervention from the host system. However, acquisition performance can be improved if the host system initialized the G- mouse following the occurrence of one or more of the following events:

G-Mouse GPS Receiver User Manual

1)The GPS receiver is not in use for more than 3 months or transportation over distances further than 500 kilometers.

2)Power off the PDA main power without system standby power.

2.2 Navigation

After the acquisition process is complete, the G-MR will begin sending valid navigation information over its output channels. These data include:

1)Latitude/longitude/altitude

2)Velocity

3)Date/time

4)Error estimates

5)Satellite and receiver status

4.2Install USB Driver

1)Insert the CD-ROM: [GPS Driver&Manual] into the CD drive. Please make sure that the

auto-play function is enabled!

2)Please follow the screen guide and click [Install/Remove G-Mouse Device Driver]

3)Please follow the screen to install the USB driver. Maybe it is necessary to reboot PC, please reboot as it says.

4)Insert the G-MR USB connector into any empty USB slot, now your PC will

recognize the USB device automatically. You may use the G-MR freely now.

4.3 Verify the Driver Installation

Please identify the COM port ID after you install the G-MR USB driver:

1) Click [Start], [Setup], and click the [Control Panel].

Page 7

G-Mouse GPS Receiver User Manual

2) While the windows of [Control Panel] shows up, double click the [System], [Hardware] and click the button [Device Manager]. Expend the tree node [Ports(COM&LPT)], you should see the item [Prolific USB-to Serial Comm Port (COM#) ]. If so, it means you can use G-MR correctly now.

3)The ???#??? mark means the COM port ID simulated by the USB adapter. Most of the GPS navigate software use COM1 as default settings. You should change it to the corresponding port ID mapped by the USB adapter, and G-Mouse can report GPS message correctly.

5.Warranty

The G-MR is warranted to be free from defect in materials and functions for one year from the date of purchase. Any failure of this product within the period under normal conditions will be replaced at no charge to the customers.

This warranty does not cover failures due to abuse, misuse, accident, or unauthorized alteration or repairs, inappropriate disassemble.

6. Trouble Shooting Guide

6.1 Satellite Signal Problem

It is normal if you found that the GPS satellite signal very low or absolute missing:

??While you are in a tunnel, GPS signal isolated.

??There is something cover above, GPS signal isolated.

Page 8

G-Mouse GPS Receiver User Manual

??Inside of the building, GPS signal isolated.

??Buildings near by, GPS signal interfered.

??Inside the forest, lots of covers above, GPS signal level down.

nIf you use G-MR inside the car, some sun-control film will makes the GPS signal low or lost.

nGPS satellite is owned by America army, sometimes they will tune -down the accuracy by some reason. In such cases, the GPS position may not fixed exactly.

6.2Position Fixing Problem

The position fix problem below does not mean the G-MR GPS receiver ???s malfunction:

??You are driving on the freeway, but the GPS navigation software shows you are on the road beside. Or the opposite situation.

??You are driving on a grid like lane, it is possible to show your car on an incorrect lane, if these 2 lane very near.

??If you translate the GPS receiver inside somewhere with no satellite signal, the GPS position may stay at the position before.

6.3 GPS Not Fix Problems

If you see [GPS not Fix] message on the screen after you enable the G-MR GPS receiver, please consider the possibility below:

nPlease wait few minutes more. GPS position fix may cost several minutes.

nPlease make sure that you put the G-MR GPS receiver at a proper place. Some sun-control

film for car may cutoff the satellite signal. You may replace it and try again.

Please make sure that you are not inside of somewhere the GPS signal shaded. Please reference the chapter [Satellite Signal Problem] about this.

6.4 G-Mouse Driver Confliction Problem

If you notice that the PC???s mouse cursor is in panic, or you just can???t find GPS device in your GPS navigation software, please follow the steps below to check:

1)Please disconnect the G-MR and the adapter in your package, but leave the adapter connected to your USB slot.

2)Click [Start], [Setup], and click the [Control Panel].

3)After the window of [Control Panel] shows up, double click [System], [Hardware], and click [Device Manager]. Expand the tree node [Ports (COM & LPT)], see if something like [Microsoft Serial BallPoint] or [Microsoft Serial Mouse] there.

4)Right click on it and select [Disable].

5)Re-connect the G-MR and your accessory, the G-MR will back to work normally now.
