GX-50/60/65 setup instructions:
Power the GX-50/60/65 up and turn it on while holding down the leftmost and rightmost “smart keys.”
Rotate the LARGE knob to the Serial Interface Configuration “CH RX TX” page. Press SEL (the selection fields will start
flashing), rotate the LARGE knob to select the port, rotate the SMALL knob to select the desired configurations, then press
ENT when complete.
If the GX unit has no GPSS capability, select “MOVING MAP” For CH 1, Tx column and wire to pin 5 of the GX unit;
if the GX unit does have this feature, select “GPSS” for CH 2, Tx column, and wire to pin 22 instead.
To restore the GX-50/60/65 to normal operation, switch its power off, then back on.
Note that for the GX-50/60/65 units, the autopilot will need to be set for 9600 baud. The autopilot’s ARINC-A and ARINC-B
inputs should be left unconnected, as steering information in the case of UPSAT units is sent over the serial RS232 line along
with the ground track and ground speed information the autopilot needs.
