I can only assume this is to display traffic on the Enigma's moving map. If so, then I imagine it would be done in the same way PAW can be connected and configured on the more modern kit (RS232). I was going to input PAW to my Explorer via the Extender module (which is connected via RS232) but, in the end, decided against it. My reasons were that I use the moving map very little, preferring to use SkyDemon on an iPad Mini and that the targets are
tiny on the MGL screen. I think trying to see them would be akin to an eyesight test on every flight.
There was a write-up on this forum about connecting to an MGL EFIS but I can't find it at the moment. Likewise there was one on the MGL Forum but this was lost when they migrated to a new Internet platform and didn't import the old posts. A lot of good info lost when they did that
Another edit to add a diagram of how mine was going to be set up through the Extender. It's as simple as one wire
