Not exactly...

Here's what I posted:


Update...

I was just told by GRT that the USB ports on the HXr are not programmed to receive the type of signals from the avionics.

They
 are setup for uploading the EFIS software, downloading flight data and 
communicating with either XM weather or ADS-B devices.

The bottom line (at least as far as the reason the thread got started) was that I had about 11 devices that required serial ports. None of these devices were weather or ADS (or radar). Which meant there was no workaround for the requirement of a second EFIS screen to get additional serial ports. 


Respectfully,
Don

Last week, the discussion over what the USB ports ended with a post that Carlos @ GRT said the USB was not available for expansion or anything but software upload and data download.
Carlos is the expert, but I think he was mis-understood.


Here is the USB section of the HXr installation manual:
"USBThe preferred method of data transmission for newer devices is USB. Just like the USB port on your


computer, an EFIS USB port is easy to connect and transmits large amounts of data quickly. USBdevices do not require you to program a baud rate. The HXr has two USB ports that may be used


for two USB devices, or you may attach a USB hub to run up to three devices. Some ADS-B units,such as the Radenna Skyradar, offer USB data transmission. Software updates are also delivered


to the EFIS via USB– simply install the software update files onto a USB thumb drive from the GRTwebsite, then install the thumb drive to the EFIS USB port. The EFIS will upload the files when you


follow the Update instructions in the system Setup Guide. Most people choose to leave a USBextension cable plugged into the USB port for easy software updating. Flight and engine data maybe recorded to a USB thumb drive as a “demo file” for later examination– a useful feature for


collecting flight test data."
