BK Serial lead connections
FYI, having spent 11 months trying to get the AV8OR hooked up to a Trutrak autopilot, this is what I found:
The AV8OR had no NMEA output (even with the later software); this took 10.5 months to find out, whereupon the agent swapped the unit for one that did have NMEA output.
The BK serial lead has to be used (although it is possible to rig something else if you know how the output pins are configured).
The "mini USB" connector on the AV8OR has 10 pins. The top five of these pins will engage with a normal mini USB connection for connecting to computers etc. using a standard 5-pin mini USB plug. However, none of those 5 pins are connected on the BK serial lead.
Two of the other five pins on the AV9OR mini USB have RS232 input/output; these two pins is what the BK serial lead connect to (plus the ground connection).
The BK serial lead has a 10-pin mini USB plug on one end.The standard five USB pins aren't connected (in fact they have been cropped off, so it is very difficult to get other connections on to it (eg a +5v power supply). There is no 'conversion' in the serial lead; it is wired straight through.
If anyone knows where to get 10-pin mini USB plugs, please let me know (other than a minimum order quantity of 10,000 from China).
With this knowledge, Section 5 of the BK AV8OR manual starts to make sense, but the manual was written by someone who probably knew this already!

Hi Pete,
Works great with my AP. I have heard the AV8OR has been tested and works with Tru-Trak, Trio and Dynon APs. I used the USB to serial adapter available from Bendix King. You really only need 2 wires from the USB port, data out and ground (They are pins 2 and 5 on the db-9 serial connector, dont know what they are on the usb port) Make sure you dont run ships power to the USB port because it uses 5 volts.
In the NMEA setup, I left everything at the default values, except I had to enable the GPBOD sentence.
