User Manual Bluetooth GPS Receiver BT-308 BT-308 at a glance 1. Introduction The BT-308 is a GPS receiver with Bluetooth interface and built-in active antenna for high sensitivity to tracking signal. Based on the SiRF star e/LP low power chip set and supports all functions(SingleSat updates in reduced visibility, Superior urban canyon performance, FoliageLock for weak signal tracking, etc.). The BT-308 is well suited to system integration and users who use PDA, Smart phone, Tablet PC and Notebook PC with Bluetooth devices. It satisfies a wide variety of applications for car navigation, personal navigation or touring devices, tracking and marine navigation purpose. 1.1 Package Before you start up, make sure that your package includes the following items.

You can either use the included two chargers or an iPAQ-compatible AC adapter. Please note that the adapter rating 5V, 1.2 A, positive pole center. Blinking ---- GPS position is fixed Steady light ---- GPS position not fixed GPS Status LED (Green):
Bluetooth Status LED (Blue):
Blinking (Slowly) ---- Not connected to any Bluetooth devices. Blinking (Quickly) ---- Connected to other Bluetooth device. Battery Status LED (Red/Yellow):
Red ---- Battery power is critically low. Charge immediately. Yellow ---- Battery is charging now. LED off ---- Battery partially full or Battery is fully charged. 1.3 LED Function 1.4 External Antenna Basically, you dont need external antenna to perform GPS positioning with BT-308 since it already build-in active antenna. The only condition that you need external antenna is when BT-308 unit can not see the sky, For instance, when you are in any environments that GPS signal is blocked, the external GPS antenna will help to receive better GPS signal. Plug the external antenna with MMCX connector to the plug on BT-308. Place the magnetic external antenna on the roof of the car or an outdoor open-space, and make sure place it in correct direction. That is, the side with magnetic is the bottom side, and the upper side must face to sky in order to receive better signal. Notice:
Hold the antenna connector while you plug the external antenna into the BT-308 or unplug the external antenna from the BT-308. Do not pull the cable line. 2. Usage 2.1. For PDA which built-in Bluetooth (Example: iPAQ 3870/3970) 1. Switch the BT-308 power on. 2. Please refer to the user manual of PDA to enable the Bluetooth of PDA connecting to the BT-308. Some PDAs may need the Bluetooth passkey, the passkey is 2003. 3. Check the number of COM port used by Bluetooth.(Example the iPAQ 3970 is the output port COM 8). 4. Running the suitable mapping/navigation software and select the correct COM port(iPAQ 3970 is the output port COM 8)& baud rate : 38400 2.2. For PDA with Bluetooth Compact Flash card 1. Switch the BT-308 power on. 2. Please refer to the user manual of Bluetooth Compact Flash card to enable it connecting to the BT-308. Some Bluetooth devices may need the Bluetooth passkey, the passkey is 2003. 3. Check the number of COM port used by Bluetooth.(Example COM 6). 4. Running the suitable mapping/navigation software and select the correct COM port & baud rate : 38400. 2.3. For Notebook with Bluetooth device 1. Switch the BT-308 power on. 2. Please refer to the user manual of Bluetooth device to enable it connecting to the BT-308. Some Bluetooth devices may need the Bluetooth passkey, the passkey is 2003. 3. Check the number of COM port used by Bluetooth.(Example COM 6). 4. Running the suitable mapping/navigation software and select the correct COM port & baud rate : 38400. Note: Most of the applications, the Bluetooth device have an auto-detect feature that you do not need to select Baud Rate. 3. How to test your Bluetooth GPS Receiver ?
The testing program only supports the Microsoft Windows CE & Pocket PC based PDA platform. 1. Run the GPSinfo.exe to execute the installation procedure of testing program (via PC and ActiveSync). 2. Run the GPS Information program from Start Program files of PDA. Here is the description of GPS Information testing program as follows:
User must select COM port , Baud Rate (38400) and click the [Star GPS] button to start receiving GPS data. Note: Most of the applications, the Bluetooth device have an auto-detect feature that you do not need to select Baud Rate. 3.
