3 Chapter. -. Brief Introduction of GPS demo board Product Figure Produce (Top View). Great for GPS based tools or appliance development.. Three useable ports, USB->UART Bridge based on CP0, legacy RS port, and an optional Bluetooth simulated RS port.. Module compatible with Ublx TIM-LC module in pin out.. Module use unav 0 baseband processor, 00 RF frontend, th generation, -dbm sensitivity.. Low power consumption Page

4 . Could locate with the antenna inside the room and meter away from the window (normally when over satellites in view site).. Orion Analyzer software and U-Center software provided, Baud rate, NMEA output package selectable. (GPS module baud rate is constant 00bps.). Pulse per second signal selectable. (Not in the standard Rom, could be flashed into the module, we would not provide any warranty if the module failed in update.). All communication method could work together. All ports could control the module and accept NMEA data. 0. USB port and Bluetooth port can not modify the baud rate, user can only modify NMEA output package through those ports.. Through RS port, all parameters could be modified.. Update may cause module fail permanently, and will cause warranty void. If user wants to do update, user must use a RS port (not USB bridged type) to update firmware. -. Accessories Figure Accessories. One active antenna. One USB Connecting Line Page

5 Chapter. Getting Started +.V Nema Output Busy Updating Firmware Pulse Per Second +.V CMOS LEVEL CMOS LEVEL GPS_Dataout +.V GPS_Dataout GPS_Datain Pulse Per Second Press And Hold During Press For Reset Firmware Upgrade Figure.Connect the SMA connector of the Active antenna to the demo board and tie the screw (Shown in Figure ). Put the antenna to outdoor and keep the top side face the sky. The antenna has integrated magnet, so it can be magnetized on any iron surface such like roof of your car. Try to place it with a large viewable angle of the sky, if covering with any metal material, the signal would be weak. You could only use.v type active antenna with this demo board, V active antenna will not work. Keep the top of the antenna face the sky, or the signal may be too weak. Most active antennas are anti water type, they could work in raining days.. Connect the USB->UART Bridge based on CP0 to your host computer with the USB connector. And tie miniusb to the demo board. Power on your host computer and install the driver. This GPS module is compatible with NMEA. protocol, so it could work with most GPS software which will accept NMEA protocol. For testing use, you could find Orion Analyzer software and u-center evaluation software in the accessory CD. It is only for testing and studying use. We do not provide any support on how to use Orion Analyzer or u-center, please view the user s guide from Orion Analyzer and u-center carefully. And notice don t try update firmware with Orion Analyzer or u-center, it may damage your module. Your demo board should work after those steps, if you have any further questions, please read the schematic and user s guide carefully, and you could also to support@sure-electronics.net, we will try to solve all questions.
