For starters, I am not familiar with the DMX protocol.  I am, however, in
theprocess of coding for a PC design in wich I used a Maxim MAX3100 to create a
2nd RS232 port. The 3100 is NOT an easy chip to use - if I had it to do over
again, I wouldn't.

Since you indicate that you are TRANSMITTING only, the 3100 would probably work
for you without too much trouble, but if you ever want to RECEIVE it is a pain.

Just my experience with the chip speaking - your mileage may vary.
