Well, this is Trimble Lassen ACE-III board. I have some of them. You could 
connect them to your system via 8-pin connector. There are two serial 
channels (one is for TSIP protocol, another is for NMEA), voltage levels 
are CMOS and you should power the board with 5 volts. You can take the 
pinout from Lassen LP board.
