Hi,
I have connected a GP330B GPS receiver to data 1 of an RDP-149, and GPS position, date and time are displayed correctly but cannot get GPS Fix position data and shows no satellite status. I checked on port monitor and GGA sentence data is present, together with GLL, RMC, ZDA, VTG and DTM.
I did a little googling, I read somewhere that for a GP330B receiver, GSA and GSV sentences are necessary for satellite status. However, the RDP-149 does not have a GSA and GSV sentence option - could this be the reason that the satellites aren't shown? And what could be the reason for "No GPS Fix"?
On Nav setup: Position source is set to "ALL"
Output format: NMEA0183 Ver 2.0
WAAS Setup: Mode - ON, Search - Auto, Corrections data set - 02 (outside North America)
Your help would be greatly appreciated, thanks
