UPDATE: Zaon XRX, GRT, G-496 Info - see new post
I just purchased a Zaon XRX at the new, (much) lower price. One of the features is the ability to send TIS style data to other devices including the Garmin '496 and the GRT Horizon. The precision of the azimuth information is twice as good when displayed on one of those devices as compared to natively on the XRX screen (which is blanked when sending data to external devices).
The devil's in the details.
You configure the XRX to send data by selecting a profile. For now, the GRT can only accept "profile 2" at 57600 Baud. The Garmin's input format is proprietary so it needs the "Garmin" profile. You can only use one profile at a time. If you use the Garmin profile then you can't, for now, send GPS data to the GRT with it. That may improve in the future. The related problem for now is that the only COM configuration on the '496 that receives TIS and sends NMEA GPS also sends VHF and the GRT can't handle that for now either.
Since I use the '496 to send GPS data to the GRT and/or to the autopilot, I had to configure the XRX to send data to the secondary (right side) screen of the GRT. I had hoped to send the same signal to GRT and Garmin, but for now, it's not to be.
The XRX manual is silent on this so I'll tell you what I had to find out with a phone call: The 9-pin connector sends data from pin 2 and pin 5 is the ground. No change is needed in the switches from factory default. You can build your own connector; no need to buy their$.
The GRT can accept the serial data on any port, but serial 6 in is pin A-24 and that's what I used. GRT configures a given port to only one Baud rate which applies to both input and output so you have to choose one where the 57600 rate won't interfere with whatever is on the output side, if anything.
I've updated the pictures of my panel on my website, but I haven't flown with this yet, so perhaps there's more to come.
