Heading data options for RDP139/VX2

Hi

Sorry if my questions are somewhat confusing. Aardvark have set the device to convert HDM nmea data into AD10 format, so my question is whether the Arpa board requires Magnetic or True heading data in AD10 format, if that helps at all.

Have included wiring schematic from Aardvark
 
The right way would be to have "TRUE" AD10 come in and then setup the bearing under radar setup as TRUE (in the installation setup). If you want Magnetic, you then setup your display heading type to magnetic under your display settings and the unit will calculate magnetic using the magnetic variation. If you try to use magnetic AD10 it can be a problem for the Vx2.
 
Hi

An update for your records to confirm that the Aardvark 3 with an HDG (not HDM) processor does successfully convert NMEA0183 heading data to AD10 form, so I have ARPA in full

Aardvark were very helpful.

best regards
