Autopilots
The GX50/60/65 may use the avionics outputs and serial interface to connect to an autopilot.
GPSS information for roll steering is provided to the appropriate autopilot. See Table 5, or
contact Customer Service.
CDI
The GX50/60/65 may use the avionics outputs to connect to a CDI. A CDI tested with
GX50/60/65 is:
• Mid-Continent Model MD200-306
Switching Relays
Typical installations require an 8-pole relay for navigation source selection without the
glideslope connections, or 12-pole with glideslope connections. Several relays suitable for
navigation source selection include:
• RS08 relay (8-pole) from Northern Airborne Technology (NAT)
• RS12 relay (12-pole) from Northern Airborne Technology (NAT)
• AIS 80-1 CDI switch unit (8 pole) from Avionics International Supply
• AIS-12020 remote switch unit (12 pole) from Avionics International Supply
Several switches that can be used to control the relay and for annunciation include:
• PB08 switch/annunciator from Northern Airborne Technology (NAT)
• Series 582 switch/annunciator from Eaton
Altitude Encoders & Converters
The GX50/60/65 can use altitude data from encoder or converter units that output information
on an RS-232 serial interface. Check the altitude input requirements on page 36. The serial
interface specifications required from the encoder or converter units are included in
Appendix E.
Several altitude encoders compatible with the GX50/60/65 include:
• Model AK-350 altitude reporter (encoder) and AK232C serializer from Ameri-King
Corporation
• Model AK-350-RS232 altitude reporter (encoder with serial data output) from Ameri-
King Corporation
• Part #8800M altitude encoder from Shadin
• Model SSD120-RS232C-1 altitude encoder from Trans-Cal
Several altitude gray code converters compatible with the GX50/60/65 include:
• Part #9000 gray code converter from Shadin
• Model IA-RS232C-1 interface adapter from Trans-Cal
• Model 3000U altitude serializer from Icarus
Fuel / Air Data Sensor
The GX50/60/65 includes an interface to a fuel / air data computer that provides fuel flow and
airdata information for the GX50/60/65 navigation displays, and also altitude input.
For fuel/air data computers compatible with the GX50/60/65 see Table 5, or contact Customer
Service.
