Perhaps I said it in a way earlier that wasn't too clear.
If you don't use the LOR software, but use Vixen or LSP or any other SW that puts out DMX, you can use both the Lynx controllers and the LOR controllers with just a single USB-DMX dongle. LOR controllers understand DMX protocol, which is the same protocol that the Lynx stuff uses. However, I believe the pin-outs on the RJ45 cables may be different between the Lynx and LOR controllers.
And, yes, you can use both the LOR dongle and the DMX dongle together, both plugged into a different USB port on your computer. Each dongle appears to your computer as a different COM port. This requires the software that you use to be able to handle multiple outputs and multiple protocols. As far as I know, LOR doesn't do this. Vixen and LSP do. But I've never used the LOR software, so I'm not the expert.
