Does anyone know the dimmer phasing on a portable Colortran 192 pack?

As long as we're on this subject, to set starting dimmer to address #1, set thumbwheel to zero. For 13, set to 1; for 25, set to 2, and so on.

Another oddity: the Control Module could drive up to 24 dimmers. Every other pack could be "dumb," containing an expansion module connected to the main with a DB-25 cable.


Relive your parachute pants and Member's Only jacket days with those 1985 dimmers.

Roommate got a curious stare yesterday when he said to a twenty-something co-worker "It's not like when you could pull the TV's tubes and take them to the grocery store's tester to see which ones needed replacing."

Also while we're at it, a standard D192 pack may not accept DMX512, just Colortran CMX. DMX512 required the crystal to be changed to 4 MHz, and one resistor to be changed to another value. However, don't ask me which resistor or what value. I invented the mod, but it's been 24 years, and those brain cells ( and the schematic) are long gone!

For anyone that needs to know details of the mod, Steve Short at Lite-Trol can probably help.
