Hi Duane,

We're engineers, so we are better at answering questions about how things work and interface, but we know that dealers are accepting orders and should be receiving stock soon.

Thanks for your interest,
Steve

Good thread! Good questions and excellent answers.

Question to Steve:

The GTX 345 Installation Manual states that a fan is not included or needed. The mechanical drawings Figure B-2 shows a VENT opening in the unit and the rack.

Question; is this vent opening only used if a fan is used on the back of the chassis, or do I need to mirror the vent opening in my radio stack side plates?

Hello Noel,

Good question.

The side vent was added to the design just in case a fan was needed, but a fan is not needed and neither is the side vent.

You may install the GTX 335/345 in a radio stack and not worry about blocking this side vent in the rack.

The installation manual is not yet production released, and we are adding this guidance before doing so.

Thanks,
Steve

Garmin GTX 345
 
Has there been any news when this unit will be released?

Question to the experts:

It looks like I will be replacing my America-King blind encoder (outputs Gray code). The GTX 345 can be optioned with a pressure sensor module (011-03080-00) and it attaches to the Static system in place of the blind encoder.

So, the Txponder gets the needed altitude info. Does the GTX 345 also output this info in a RS-232 interface or ARINC interface available to other devices?

Thanks.

Hello Noel,

Good question.

Yes, one of the 4 GTX 345 RS-232 ports may be configured for "ALT FMT 1" format which transmits the pressure altitude data from the built-in pressure sensor module.

It is a fairly standard serial encoder format that is probably usable by a wide variety of devices. The ASCII character format of this transmission is documented in Appendix A of the installation manual.

Thanks,
Steve
