DMX CONSOLE CONNECTIONS

DMX console signals to the AR-1202 should be

transmitted over a twisted pair, shielded, low

capacitance cable. A DMX console transmits from a

female, 5 Pin XLR Connector.

See the EXTERNAL CONNECTIONS and the

example below for specific connection information.

DMX TERMINATION

A DMX bus should be terminated (only) at the last

receiving device on the chain. This is done by

connecting a 120 ohm, 1/4 watt resistor across the

DMX DATA - and DMX DATA + lines.

A DMX bus should be daisy chained to all its

receiving units. It should NOT be connected in a star

arrangement with multiple "home runs".
