Strand Lighting CD80 - Connect Control Signal

5.3 Connect Control Signal
COBO Dimmer Racks accept control signals conforming to the USITT AMX192
Dimmer Signal Specification.
Short extensions of the multiplex signal, where
TA4{fY4 connectors are used,
are made with Belden cable #8723 (2 pairs of shielded 24 gauge wire). All other
runs (in or out of conduit) are made with Belden #9156 (2 pairs of unshielded
18
gauge wire). Maximum allowable distance from control console to last dimmer
cabinet is 1000 feet.
The three types of connections provided in Strand Lighting equipment for the
AMX192 signal are the XLR style connector, the TA4{fY4 Series Mini-SwitchCraft
connector, and terminal blocks. COBO 1.2Kw Packs use XLR connectors for
control signal connection. Pin assignments are shown below.
