Eric- To answer your questions, the original set up only had the Aera660 which provided GPS data to the engine monitor/elt and to MiniGAs, using one port for the monitor/elt and the other port for th ...

Problem solved. There was a short in the wire to the elt. I found that by checking the output side wiring to ground instead of end to end. I separated the spliced output wires and found the short w ...

I hadn't checked the grounds for the engine monitor and elt. I had also considered disconnecting the connectors for the monitor and elt in turn to see if one could be a bad actor. Unfortunately sepa ...

I swapped the pins on the output side of the d-sub. Pins 6 and 7 set to MapMx work properly. Pin 9 set to NMEA does not (the same as when it was on pin 7). The wire continuity for the output side f ...

Dan-

Agree with 1 and 2 as the possible causes, which is what prompted my initial question. I would be very surprised if it was 3 since the only change was switching the mode for pins 8 and 9 from ...

Thanks. To clarify, I would only connect pin 7 but not pin 1 to the converter.

The 232 outputs are different. In the present configuration all pins are connected to the Aera but pin 6 is not conne ...

Dan- A couple of questions on how to use the breakout converter. 1. Would I connect pin 7 (RS232) to the RS232 TX terminal and pin 1 (gnd) to the RS232 GND terminal? 2. Would a USB port on the panel ...

I'm not sure how those connectors would work. In my case the bare wire cable from the Aera goes to a 9 pin d-sub, pinned as follows:

1-Black (gnd)
2-Red (power)
3-Green (audio common)
4-White ...

Is there a way to test if one of the Aera660 RS232 output lines is producing an output? For example, using a multimeter on the output pin in the connector? I'm trying to send NEMA data to an engine ...

Just for grins I decided to test my two stereo headsets. Both of them did not test on the right (ring portion of jack) speaker. I borrowed another stereo headset and eureka, both speakers worked, an ...

Further troubleshooting is leading me to believe in a coincidental failure of the radio. I disconnected the Aera from the radio harness and still no joy on the right side speaker for both pilot and c ...

I recently switched the shielded 3 wires from a mini music jack to an Aera 660 to provide audio alerts through a GTR200. The three wires connect to pins 18 (music R), 19 (music L), and 37 (music Lo) ...

Thank you. I guess my confusion comes from the terminology used on the pin-out diagram and description table where the pin is labeled "in".

An additional confusion point is the GTX 327 ...

I'm in the process of making the wiring harness for a GPS 175 installation and would like to have the automatic power on feature. I am confused by the information in the installation manual though an ...

Does anyone know of a source for "clamp-on" coax (or other wiring for that matter) clamps? These clamp to the fuselage bulkheads rather than mounting with screw holes. The two "wings&q ...

Here is the original wiring diagram from the Alon maintenance manual (if I successfully added the attachment). The wiring has changed with the addition of an alternator in place of a battery. The ci ...

Reviving an old thread, when the original generator was swapped out for an alternator they utilized only one pole of the two pole switch to connect the batter to the bus, leaving the other side unused ...

How about D-Sub pins and sockets? If LEDs, then they are unlikely to need
disconnecting. Don't use connectors. If not installed, they can't fail.

I had thought about those per previous researc ...

I have searched unsuccessfully on how to connect post lamps or LEDs that have pig tail wires attached and that mount from the front of a panel through a 1/4" mounting hole. If it is ever necessa ...
