You might want to get a copy of the actual DMX specification.

There is no ignore or carry on or anything, if you use the standard
start code ALL slots are valid.

The specification says you can send less than 512 slots, but there's a
lot of gear that freaks out if it doesn't get all 512.

Some gear freaks out if you send DMX at max speed.

Some gear works funny if it's Tuesday.

Be sure to get the termination right.

Grounded transmitter, isolated receivers.

Only one transmitter unless you're running RDM.
