Hi,
I was able to sort this out.
NC expects all the ports to be occupied as per the set up defined. So in my case I had to connect LOR, X Dongle for dumb RGB and Cat 5 for e 632 all together.
Moreover the COM port in which I was attaching the X Dongle was actually COM4. I was assuming this was COM2.
Took a long time to trouble shoot but over it now.
Now I am trying to attach an audio file for the xseq sequence.
Regards.
