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 was on the elt side. Also, the LED tester
for the elt works to check the RS-232 output from the Aera, flashing at
each data transmission (either fast or slow).

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 the Minis. After I installed the GPS175
I used the port from the Aera that provided GPS data to the Minis and connected
it to the GPS175 and changed that port's format to Garmin's MapMX from NMEA9600.
That allows the Aera map to display a detailed route depiction on a
larger screen than the GPS175. The Aera does not provide any GPS data to the
GPS175 but still has its own GPS receiver. It passes that data out the port set
to NMEA9600 and goes to the monitor (and formerly the elt). The GPS175 is
providing navigational data to the MiniGAs now instead of the Aera. I'm currently
using two of the three GPS175 ports and both Aera ports. The Aera is basically
a larger map display for the GPS175 that also shows ADSB traffic via a
GDL50 Bluetooth connection. The Aera can be used as backup flight instrument
in case of electrical failure since it a the GDL50 have internal batteries and
the Aera has its own GPS receiver and has the active route in its memory. It
just can't be used to shoot an actual approach. I also have a handheld radio
for communication in case of electrical failure.
