Don,
I GOT IT TO WORK WITH DMX. Yeah!!
The solution was so simple. The hardest part is converting all the sequences to DMX via channel configuration which I knew I did correctly. After that:
1) Update LOR Network Preferences - LOR tab - none on regular network; DMX tab - this should find the RS485 dongle, select it and RAW DMX.
This actually does not affect the XL execution of sequences but it is an easy way to test in LOR SE to see if your DMX set is working. I ran a sample sequence in LOR and the lights worked fine so I knew I had the DMX setup correctly.
2) XLights - Setup tab - this is key, I changed the LOR network type to OPENDMX with my com3 port. That was it.
3) Convert your LOR sequences in DMX config back into xseq, combine your RGB models and run.
I was trying to use the DMX network type with my RS485, but it needs to be OPENDMX. That was the difference. By default, it uses baud rate of 250000.
Just passing this along in case it helps you and anyone else.
Thanks for helping me earlier this week. I do appreciate it.
