On this side, I'll put down some information on how to connect the Conrad-Electronics "GPS-Mouse" GX107 to a PC.
The mouse has a small PCB connector and is designed to work together with a GSM module to remote control whatever system you want via SMS messages.
After some measurements, I figured out how to connect it to a PC.
|Wire WHITE||GPS RX||connect to +5V via 10k|
|Wire GREEN||GPS TX||GPS NMEA Strings as inverted TTL Signal|
|Wire BLUE||"enable"||connect to +5V|
|Wire BLACK||POWER||connect to +5V|
To power the GPS-Mouse, I used a TRACOpower TEL 2-1211 DC/DC converter. The inverted TTL signal from the GREEN Wire has to pass an MAX232 to reach the COM-Port.
