G35L GPS Data Logger

1. Introduction The G35L GPS data logger is a high performance GPS recorder and vehicle tracking system for passive tracking applications. The G35L can be used as a passive GPS receiver while it simultaneously logs the position data to its on-board flash memory. The logging interval is user definable either by time from 1 to 65535 seconds or by distance from 1 to 65535 meters.

The G35L supports data download through RS-232, USB, and optional Bluetooth interfaces. When a Bluetooth dongle is used, the G35L supplies DC 4.5V power to the Bluetooth dongle.

The G35L can satisfy a wide variety of applications for vehicle navigation, security tracking, fleet management, map making, or leisure purposes. In automotive applications, the SiRF architecture supports advanced tracking capabilities through fast recovery times combined with reliable operation in “urban” environments and areas of dense foliage. The G35L is ideal for commercial and professional applications such as precision agriculture, geographic information systems (GIS), and mapping.

The G35L allows for a wide range of power supplies such as a vehicle battery or standard USB interface.

2. Software Installation

2.1 Install G35L USB Driver Note: For PC without USB interface, skip USB driver installation. Installation Steps Step 1: Put G35L Driver & Tools CD into the CDROM of your PC. Make sure that G35L is not connected to the PC through USB cable at this moment. Step 2: Under directory /USB Driver, double click “CP210x_VCP_Win2K_XP_S2K3.exe”, and then follow its instructions to finish the pre-installation process.

Step 3: After the pre-installation above finished, connect G35L and PC through G35L USB cable.



After USB cable connected, the “power” LED on G35L front panel should be on; meanwhile on the screen there is message window “Found new hardware” and “Found New hardware Wizard” present.

Tick “yes, this time only”, then click Next. Step4: Tick “Install the software automatically (Recommended)” and click Next.



Step5: Follow the instructions on the screen and leave everything as default, finish the remaining installation.

Finally, a message window will present on the bottom of screen: “Your new hardware is installed and ready to use”. Up to now G35L USB driver is installed successfully.

NOTE: After Step 5 finished, some computers may still indicate “find new hardware” and pop up “Found New hardware Wizard” window again as in Step 3. In this case, please redo Step 3 to Step 5 to finish installation. Step 6: Review COM port number. After G35L USB driver is installed successfully, G35L USB is mapped as a virtual COM port, which can be reviewed at “Control Panel System Hardware Device Manager Ports (COM & LPT)”:



This virtual COM port number is needed when running Data Logger download and configuration utility.

NOTE: 1. The virtual COM port number may be different depending on the configuration of PCs. 2. When G35L USB cable is unplugged, the virtual COM will disappear on the above window. It

presents automatically when G35L is connected to PC through USB cable.

2.2 Copy Data Logger Utility to PC Data Logger Utility (Data Logger Driver&Tools CD: /Data Logger Utility.exe) is used for downloading and configuring Data Logger settings. It doesn’t ask for installation. Just copy it to your PC, anywhere at your convenience, and double click it to run. Please refer to (5.1-5.3) about how to operate the utility.

3. G35L Device Connection

3.1 Power Connection G35L can be powered either by vehicle battery through one power cable, or by standard USB interface of a computer through USB cable. G35L allows being powered form both power cable and USB cable simultaneously. When G35L is powered, the PWR LED on the front panel is ON (red color).

G35L power supply must meet the requirements:

Through power cable interface: DC 7-80V

Through USB cable interface: DC 4.5-5.5V

Caution: Over-voltage power supply may damage the device.

3.2 Antenna Connection G35L is equipped with P2-SMA antenna.

3.3 Communication Connection G35L provides standard USB (Type B) and RS232 (DB9, DTE) interfaces to communicate with host PC or Laptop. It outputs standard NMEA message continuously in real time through RS232 or USB interface. G35L allows configuration, download data or update firmware though RS232 or USB interface.

When both USB and RS232 cable are connected, only RS232 communication is active. In this case, USB is used only for power supply.

G35L also support standard RS-232 Bluetooth dongle (DCE interface), it supplies DC 4.5V power to RS232 Bluetooth dongle through pin 9.



4. GPS Data Logging After G35L is powered through USB cable or its power cable, G35L starts data logging process automatically based on data logging mode settings.

4.1 Data Logging Mode There are five configurable logging modes:

• fix with time interval: G35L logs data with time interval after GPS fixed.

• time interval: G35L logs data with time interval no matter GPS fixed or not.

• fix with distance interval: G35L logs data with distance interval after GPS fixed.

• fix with time or distance interval: When GPS fixed, G35L logs data at every time internal and every distance interval.

• fix with time and distance interval: When GPS fixed, G35L logs data when both time internal and distance interval are reached.

Please refer to (5.3) about how to configure data logging mode.

4.2 Data Logging Indication While G35L logging data, the “LOG” LED on the front panel keeps on flashing. When “LOG” LED be solid ON, that indicate logging memory is full and data logging stopped. If “LOG” LED stays OFF, it indicates that data logging requirements are not satisfied with its specific logging mode.

5. Data Download and Configuration G35L data download and configuration is implemented with Data Logger Utility through USB interface or RS232 interface.

5.1 Running G35L Utility As mentioned at (2.2), copy the file “G35L Utility.exe” from Data Logger Driver&Tools CD to your PC. Suppose you build a directory as C:/G35L and save the utility file under C:/G35L/. Double click “G35L Utility.exe” to start the utility:



Connection Steps

Step1: Select COM port

If G35L is connected to PC through USB interface, then select USB virtual COM port. USB virtual COM port number can be found at “Control Panel System Hardware Device Manager Ports(COM & LPT)”, please refer to (2.1 Step 6) for more details.

If G35L is connected to PC through RS232 interface, then select corresponding RS232 port.

NOTE:

When both USB and RS232 interface are applied, only RS232 COM port should be selected for G35L utility. In this case, G35L can be powered through USB as normal, but can not communicate with PC through USB cable.

Step 2: Select baud rate

Select the baud rate of G35L. G35 is set to 4800 baud rate by default.

NOTES:

1. G35 is set to 4800 baud rate by default.

2. The connection will be failed if G35L baud rate mismatch the selected baud rate. Users must remember what G35L baud rate is after G35L baud rate is re-configured.

Step 3: Input password



Input the 4-digit password you set before.

NOTE:

There is no password for G35L by default, so there is no need to input password if you never set it. Step 4: Click button “Connect”. If COM port number, baud rate and password are correct, there are messages “Logging…”, then “Login Ok”, then “Device connected” on the bottom of the utility window.

NOTES:

In the following are possible failure messages on the bottom of utility window after click “Connect” button:

1. “Open port error”

This message indicates wrong COM port number being selected, or no cable connection. Please check your COM port number at “Control Panel System Hardware Device Manager Ports (COM & LPT)”, and check your cable connection.

2. “Failed to connect the device”, then “Device disconnect”.

It indicates the COM port selection is correct, but bard rate selection is wrong.

3. “login failed, change password and try connection again”

Input wrong password.

5.2 Data Download and Clear

Download Data

Step 1: Input the name and path of the file where the logged data will be saved to.

Caution:

If one existed file is selected, it will be overwritten by new data. It the file does not exist, it will be created automatically.

Step 2: Click button “Download” to start the download. Download data operation does not remove the logged data from G35L.

Clear Data Click button “Clear” to clear the logged data.

NOTES:

1. It is highly recommended to download data with baud rate 115200. Download data at baud rate 4800 is very slowly. Please refer to (5.3) about how to configure baud rate.



2. While G35L utility is running and connected, GPS data logging process is stopped.

5.3 G35L Configuration G35L allows user to configure the following items:

• Serial No. Users can define a serial number for each G35L device.

• Password User can set a 4-digit password to protect GPS data from downloading.

Caution:

If you set password and forget it, you have to provide detailed device information to Laipac for help. No super password exists for the sake of security, and restoring the password involves complicate calculation. So be careful with your password!

• Log Mode User can set the following data logging mode according to specific applications: 0: fix with time interval: G35L logs data with time interval after GPS fixed. 1: time interval: G35L logs data with time interval, no matter GPS fixed or not. 2: fix with distance interval: G35L logs data with distance interval after GPS fixed. 3: fix with time or distance interval: When GPS fixed, G35L logs data at every time internal and every distance interval. 4: fix with time and distance interval: When GPS fixed, G35L logs data when both time internal and distance interval are reached.

• Logged by Time Set logging time interval, from 1 to 65535 seconds.

• Logged by Distance Set logging distance interval, from 1 to 65535 meters.

• NMEA Baud Set G35L communication baud rate, from 4800 bps to 115200bps.

After setup above items, click button “Save setting” to save all settings.

NOTE: When NMEA Baud is changed and saved, it does not take active until you exit or disconnect the utility. Before you exit or disconnect the utility, the actual communication baud rate between G35L and the utility keep unchanged.

For instance, suppose you login the utility with baud rate 4800 , and you want to download data with baud rate 115200, then you need to take the following steps: 1. Select 115200 for “NMEA Baud” item.



2. Click button “Save setting”. 3. Click button “Disconnect” to disconnect G35L. 4. Select baud rate 115200 under “Communication Settings” 5. Click button “Connect” to reconnect G35L.

After the connection succeeds, you can download data with 115200 baud rate.
