My 4402X receives signal on TP1 (1430L) but does not map a channel 900, so I never get the ZK Authorized light. I've unplugged the unit to force a new download of the VCT table and still nodda. None of the 900's map. It did show a VCT 215 as well at some point in my testing.
FINALLY found what I was looking for. They changed the virtual channel numbers around as well as the transponder (which I knew the TP changed based on information provided here). The DMX channels are in the 200 range in the virtual channel maps for VCT214.
Thanks to everyone involved in helping get this figured out!
