Difference between GMA 245 and 345?

[supik]

Steve,

Is it all valid for the gma 345 as well? I'll need the marker beacons here in Europe..-unfortunately

Thanks a lot!

I guess the COM FREQ SWAP is not available with the gea24 & gma345 combo as the gma345 does not talk to the g3x system.. -is my assumption correct?

Thanks,

Hello Igor,

That is correct. Presently the GMA 345 installation with a G3X Touch system supports COM SWAP (native to audio panel), but does not support the nice COM FREQ SWAP function described above because the G3X Touch system does not communicate with the GMA 345 and doesn't know which COM radio is selected on the audio panel.

We are adding RS-232 communication with the GMA 345 in an upcoming G3X Touch release, so help is on the way!

Thanks,
Steve

Hello Igor,

You are very welcome and thank you for the kind words.

The new G3X Touch interface to the GMA 345 audio panel will provide two new features:

1. Marker beacon annunciations on the PFD (O/M/I).

2. Knowledge of which COM radio mic channel is selected on the GMA 345 which allows users to take advantage of the COM FREQ SWAP discrete to swap the active and standby frequencies on the selected COM radio for the radios that are currently remotely controlled including GTN 635/650/750, GNC 255, GTR 225, GTR 20, GTR 200, and GTR 200B. This is in addition to the touch screen controlled frequency swap already supported. We understand there may also be 3rd party radios that follow the published protocols for these radios, but we haven't tested any of these units.

Thanks,
Steve

The G3X Touch V7.00 software that provides this added support for GMA 345 audio panels has now been released.
