Title: Garrecht VT-2000 Transponder
Post by: davep on June 10, 2016, 01:16:24 pm

I have just installed a VT-2000 transponder and would like to use PilotAware to feed GPS to it. The transponder installation manual says that it requires date at RS232 levels (no TTL level). I am assuming that PilotAware operates on TTL levels, in which case is there a simple and more importantly, cheap way of connecting the two?

The USB to serial dongles on sale can be bought with either TTL or RS232 levels. When you buy one (PL2303, or, I think FTDI), make sure it has RS232 specified and not TTL.

Dave,
Do you know what NMEA messages it is expecting ?
Also you need to know the BAUD rate

Thx

To quote from the installation manual:

The GPS position source needs to send GPS data via RS232 in the NMEA-0183 format at a datarate of 4800bD. The required NMEA datasets are GPRMC and GPGGA. GPGSA is an option.

So just selecting Funke will give you this data output

Thanks for your help.
Looking forward to extending the functionality of an already useful PilotAware.
