== Technical Requirements ==
Any GPS receiver meeting the following requirements:
* Female, 9-pin serial connector
* NMEA-0183 ver.3.01 compliant, including GGA and RMC sentences.


===General Information===
Some installations may require a gender changer to mate DB-9 connections. In the case of either portable scanner, if you use the cable that came with the scanner a null modem/gender changer is a requirement.  A null modem adapter is not required if you purchase the optional GPS adapter cable designed for use with the HP-1 and other DMA scanners.   


===Wiring Schemes===
* The wiring here is shown for the BCT15X and presumably the BCT15. The BCD996T and 996XT should be identical (verification wanted)

 DB9 Serial end #5-----------------Shield------------------------------GPS  ground

 DB9 Serial end #2-----------------Tip--------------------------------GPS receive data

GPS unit should have separate power supply. Beware most GPS units do not use the same voltage as the BCT15X. You can use the GPS on its battery or supply a fused power lead at the proper voltage for the GPS. The DB9 connector on the radio does not supply power to run the GPS

==GPS Internal Power Feed Modification==
The BCT15X and other scanners with rear mounted DB-9 serial connections can be modified to supply power to the [http://www.byonics.com/tinytrak/gps.php Byonics puck style GPS reciever]. You will need to disassemble the scanner and find the 5 or 6 volt regulator. Solder a wire from the output of the regulator to pin 4 of the DB-9 connector. Reassemble your scanner and plug in the Byonics GPS reciever. The LED on the receiver should start flashing, and the GPS icon on your scanner should start flashing. Both lights will glow steady once the receiver acquired a position fix.
