thx, got carried away by my ftdi rs-485 converter's arrival. so far, i can
dim rgb channels but the optima lighting 4 channel dimmer packs are a
different matter.
can't wait to try the dmx laser next

the 170Ω not being there though
you can use a single resistor instead (from 5V TX to 3.3V RX) but it
should be bigger, like 10K if that works, but not less than 1K.
hmm, chip-power-down (CH_PD) wants 10kΩ > vcc...i didn't know that.
if you see other diagrams where CH_PD connects directly to Vcc it is
probably fine.
also 10K is just a random number, anything from 1K to 100K would probably
have the same effect.
