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. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
