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.
Depending upon other equipment to be driven by the GX unit, either channel 1 or channel 2 may be chosen. If another piece of
equipment is to be driven by the GX unit, and that equipment uses the MOVING MAP format, then the DigiTrak can be driven
from the same pin as the other external equipment. (The GX unit will not allow for both of its output channels to be set to the
same output format). If there is no other equipment other than the DigiTrak to be driven by the GX unit, simply use channel 1
(pin 5) on the GX unit.
Select “MOVING MAP” For CH 1, Tx column and wire pin 3 on the DigiFlight to pin 5 of the GX unit,
OR
Select “MOVING MAP” For CH 2, Tx column and wire pin 3 on the DigiFlight to pin 22 of the GX unit.
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.
