They don't usually need the battery, after reading their website I'm guessing its outputting TSIP binary protocol...
- The Lassen LP GPS receiver has a single I/O port. The device is delivered from the factory with the TSIP protocol configured on this single I/O port. -
It needs changing to NMEA.
Edit - which you did ask!
