Hello,

My avionics shop recently installed a L3 lynx ngt-9000 and connected it to my existing IFD540 running 10.2.   The connection was made using the RS232 as described in the 10.2 documentation .   The traffic and weather info being passed onto the IFD is great.   However, I have noticed some issues and wanted to find out if this is a known issue or maybe something with my installation.

The biggest issue is that some data such as CONUS nexrad often does not completely populate on the IFD.   I typically see large sections of  US with hashed out areas as if data was not received for certain blocks.  Those hashed out areas may sometimes be across the middle of areas of significant precipitation.   At the same time on the NGT-9000 display it shows nexrad for the full US without any apparent gaps as well as complete regional nexrad data when I zoom in on the NGT-9000.  This issue of missing blocks also happens on the regional nexrad although to a lesser degree.

Also, there often seems to be a delay of several minutes between when the NGT-9000 displays weather updates and when data shows up on the IFD.   

I'm not sure if this is possibly a bug, a serial port baud rate too slow to handle the amount of data being sent, or some issue with the installation.   If anyone else has this integration running I'd be interested to hear if you have similar issues.

Regards
Karl

I don't believe the 9000 and the 540 are an approved connection yet.  Yes, It has been shown to hook up and work kinda so far but I don't think the bugs are worked out.  But sounds like minimal trouble considering a number of issues when connecting two different units.
