GRT Avionics

Where can I find the HX SOFTWARE set-Up configuration Manual? The HXR software page appears to be different.
I've set an input port to TT22 and there is NO TT22 highlighted at the top to address the AC parameters......

Install is using the Trig remote head..

Look under "equipment supplements", for the Trig TT22 supplement.
BUT, that is designed for Not using the Trig remote control head, but rather the remote main box (may be just terminology here).
You do need a special adaptor on the trig connector.

BTW, you must have the latest software in the Hx. I do not have a Trig installed, but if I set a serial port to TT22 I do see all the parameters on the set up page, just like the manual says. So try again.
