3 Terminate Wiring 21

DMX Termination

DMX requires 120 termination at the last DMX device in the control run. Since an ERn

enclosure with a Paradigm Architectural Control Processor installed can utilize up to two

DMX inputs (2 DMX runs) the right I/O board provides termination switches.

Connect ERn Left I/O Data Terminations

The left IO board supports the Paradigm Architectural Control Processor data terminations

including:

• RS-232 on a male 9 pin (D style) connector

• Ethernet on a RJ45 female connector

• Contact closure input terminations on a 8 pin pluggable connector.

• Terminations available for 4 inputs and 4 common wires.

• Contact closure output terminations on a 8 pin pluggable connector.

• Terminations available for 4 normally open outputs and 4 common wires.

Connect to Serial RS-232

Integrators and users of advanced systems can interface with the Unison system through

the RS-232 connection on the left I/O board. This connection provides an interface with

external devices capable of sending or receiving RS-232. This connection can also receive

serial commands from a transmitter and provide rack and system status when queried.

Note:

The RS-232 cable (not supplied) should follow common RS-232 pinout for a DB-

9 receptacle (pin 2 is RS-232 Rx, pin 3 is RS-232 Tx, and pin 5 is ground).

Notice the two termination switches labeled DMXA and DMXB.

Each switch has three termination positions:

• Source - reserved for RDM termination (future development).

• Off - no termination, DMX will pass through this device on to the

next DMX device in the data run.

• End - termination is on. Used if the ERn is the last DMX device

that is physically connected in the daisy chained DMX data run.

When used as a DMX output port, the termination switch should be

set to “OFF”.
