Is anybody on this forum running a combination of the GRT Sport EFIS, the VPX Sport electrical buss and the NavWorx ADS600-B box? I haven't purchased the NavWorx box yet but would like to add later. I plan to install a GRT SX100 for the passenger side as well as a two axis autopilot after I am out of phase 1 when money becomes available and then get the ADS-B box. I have already prewired for the other EFIS and autopilot. The VPX Sport is tying up the 4th serial input and output line so I am trying to figure out how to interface the serial input and output requirements for the NavWorx. My GRT Sport has the internal GPS. According to the wiring diagram I am out of connections on the GRT Sport. Were you able to get around this? I am feeding a GTX327 with the encoder output from the EFIS. One set of wires is the inter connection for the pilot and passenger EFIS and a GPS signal is running to my ACK E04 ELT.
I was thinking of using the autopilot servo wire that Stein sells to run from the NavWorx box. That would give me two 20ga and five 22ga wires for the ADS-B installation. The wiring diagram calls for shielded for some of the connections so the servo wire might be a no-no. If I have to go with shielded thats no big deal. Wire is cheap in the grand scheme of things.
I want to try to prewire for the NavWorx box while I have access in the tailcone. I have the G3 Ignition system and VPX box installed under the forward top skin so I don't have room for the NavWorx box behind the panel.
Upgrading to the Horizon EFIS which has more ports is out of the question.
