The only requirement to program the SSR4 is channel one and or channel two have a number value that you want to set the device to on the dmx data string
So if your start address is 255 or less then Channel One needs to be that number and the rest of channels are at zero
If over 255 then Channel one has to be 255 and Channel Two is the remaining
example: Start Address 340, Channel one = 255 and Channel two = 85 (hoping my math is correct)
Hope that is clearer than mud

Of course I have no clue what LOR software/hardware is sending to the dmx string.
