4. Installation
Step I：Check your GM-2 package
The standard package of GM-2 contains:
GM-2 Receiver
CD ROM
Please contact local distributor immediately if any item is missing or damaged.
Step II：Connect GM-2 to PC/Lap top or handheld device
For PS2 type: No USB Driver Installation is needed.
For USB type: please follow the instruction as below. Before the USB
connector plugs into your PC/Lap top, please have your USB Driver Installed.

Once connect your GM-2 to PC/Lap top or handheld device, Orange LED will
start flashing once power is applied.
5. How to configure your GM-2?
The GpsView program only supports the Microsoft Windows XP, Vista and Win 7 OS.
5.1. Driver Installation
Connect GM-2 to PC and then click “CP210xVCPInstaller.exe” to start the installation process. The device manager
will assign a COM port for GM-2 after USB driver has been successfully installed.

5.2. GpsView software
Open GpsView software and select correct COM port and Baud Rate and then click “On” button to establish the
communication between GM-2 and PC. If the connection is successful, the NMEA stream will keep showing.
Default baud rate of GM-2 receiver is 9600bps, if you bought GM-2 logger, please choose 115200bps

5.3. Configuration
In Setup Page, Output frequency of each NMEA can be changed from 1second to 5 seconds and Fix update–Rate can be
changed from 1 time to 5 times per second. DGPS like WASS, EGNOS, MSAS can be enable or disable. Here also
allow users to update the AGPS and record the NMEA sentence.

GGA(1), GSA(1), GSV(1), RMC(1) +
1. GGA(1) means GGA sentence output every 1 second, GGA(2) output every 2 seconds.
Note:
2. GGA(1/2) means GGA sentence output 2 times per second, (1/5) output 5 times per second.

GGA(1/5), GSA(1/5), GSV(1/5), RMC(1/5)
5.4. Update AGPS
Step1. Make sure you have network available for accessing the internet.
Step2. Connect GM-2 to PC and then open GpsView to establish the communication.
Step3. Go to “Setup” page
Step4. Click “Update” button under AGPS to update the AGPS data. The program will connect to the AGPS server and
download the data automatically. You can also check the valid time of AGPS by clicking Query. Clear AGPS data by
clicking Reset.

6. Interface
6.1. USB interface
The pin assignment for USB interface is shown in Fig-1.
6.2. PS2 interface
There are two possible interface signal level with PS2
connector, RS-232 or TTL.
The pin assignment for RS-232 and TTL are shown
respectively in Fig-1.
6.3. LED
There are two LED’s with GM-2.
Orange LED will stays on when searching GPS signal. It
will start flashing once GPS has position fix.
Optional yellow LED will start blinking once GM-2 start
logging position.

8. Troubleshooting
When your GM-2 could not operate, please follow below instructions for
troubleshooting.
1. No LED light after plugged in
It means no power is applied to GM-2. Please check if the connector plugs
in properly.
2. GM-2’s LED is flashing, but the connection between GM-2 and the E-map can
not be established. Please make sure the settings of COM Port Number and Baud
rate are correct.
Most of E-map provides scan function to search COM Port. Please scan
it for the correct COM Port number that GM-2 is utilizing.
The default Baud rate is 9600 (Receiver type only). Logger type is set
at 115200bps. For COM port, please go to the MS Windows’ device manager
to check the correct COM port first.
If a USB cable is used to connect to PC/Lap top, please make sure the
UBS driver is installed successfully.
