GRT Avionics

On page 34 of the EIS manual, it states that to update software via the EFIS, a serial output from the EFIS to the EIS must be hooked up. I have used Serial port 4 on the EFIS for serial in and serial out to the EIS, hooked to the appropriate pins 10 and 11 on the EIS.

In the software config on the HX, I have Serial port 4 set to 9600 baud, and Serial Port 4 input defined as "EIS/Engine Monitor". This works fine to allow the EIS information to be displayed on the HX.

However, I cannot find any appropriate setting for Serial Port 4 output to talk to the EIS. Scrolling through all of the options does not reveal anything that is related to the EIS. What should this be set to?

I am using the latest HX software "5d + bluetooth" released in May of 2013.

I believe this is a future option, not yet incorporated. So don't worry about it.

The EIS software update function hasn't been implemented in the EFIS yet. For now, set the output to Off.

Okay, thanks!
