I put a JPI EDM-930 into my plane at my last annual and have been unable to get it to talk to my GPS 175. I'm at a loss as to what to try next and would appreciate any suggestions. Here's what I've done so far -
Pin 8 on the GPS 175 is connected to GPS In on the EDM
Pin 30 is connected to GPS out on the EDM
I would expect these to put the EDM 930 on RS 232 #2
On the EDM, baud rate is set to 9600 and I've tried the all of the Output fomats, including #6 GNS 430/530-WP and #7 GNS 430/530-DST with no success. On the input side, I've tried all the setting, including #3 AVIATION/BENDIX with the Output from the GPS 175 set to Aviation 1, Aviation 2 and Shadin, again with no success.
I don't see a way to set the RS 232 Input format on the GPS 175, only the Output format.
I've got 2 other devices connected to the other RS 232 ports, a G5 on #1 and my Transponder on #3, both of which work fine. Prior to the installation of the EDM, the G5 was on #1 and the Transponder was on #2, I had the entire harness redone and that's how the Transponder got moved.
I'm stuck at this point and don't know what else to try. I've contacted JPI and Garmin, JPI gave me some settings to try that didn't work so I sent them another email asking for next steps. I haven't heard anything from Garmin yet but, given that the GPS works with the other devices and #2 was previously connected to the Transponder without issue, I don't really think the problem is on the GPS side.
If anyone has any ideas, I'd love to hear them. Thanks!
