Installing a Trig TY91 COM Radio

There are two options for connecting FlightView with the TY91. If you purchased and installed the Trig control head, you will need to use option 1 (FlightLink RS-232 to the TC90 Control Head). If you did not purchase the control head you will need option 2 (FlightLink RS-485 Direct To The TY91).

Connecting A Trig TT2x Transponder With FlightView

Pre-Made Harness

The TT2x transponder connects to FlightView using a FlightLink USB-to-RS485 adapter. That adapter connects the two TMAP lines (A & B) to the TMAP inputs on the Trig harness via the DB-9 connector that would ordinarily be used for the control head.

If you purchased the pre-made TT2x harness, it comes with the FlightView TT22 cable which is terminated in a DB-9. Simply plug that DB9 into the controller connector on the harness and connect the USB port to your FlightView system’s USB hub.

DIY Harness

If you opt to build your own harness rather than using the pre-built Trig harness, you will need to order a bare-wire FlightView TT22 connector. Connect the TMAP A […]
