AMX

1. aka AMX192-1986, AMX stands for Analog Multi-Plex, officially USITT standard: AMX192 Analog Multiplex Data Transmission Standard for Dimmers and Controllers, 1986, revised in 1987. Essentially, it is one of the predecessors to DMX (digital multiplex). AMX is a control protocol for some older lighting systems, including the popular Strand Century CD80 dimmer, dating back to 1979. Up to 192 dimmers are controlled via one cable of two twisted-pairs. The standard allows the original Switchcraft TA4 connector, as well as 4-pin XLR. For wiring conventions (pin-outs) and more information, see http://www.pathwayconnect.com/content/view/12/26/ .
