I'm trying to get Model 20 to communicate with SN-10B.
We know we have connection cable right.
Logger is on- 2 different 20's tried.
We get "No GPS input" and "No message received from GPS" messages.
NMEA input is selected.
Any help appreciated.
Thanks

Double-check GPS setting and baud rate on SN10:
IIRC Should say "NMEA 4800" for CAI 20.
Only 2 wires needed:
- gnd at serial connectors
- CAI TX to SN10 RX

Hope that helps,
See ya, Dave
