DMX-6PM Controller Board
The DMX-6PM controller board is the central electronic control system (aka brain) for all
DMX 6-PORT MERGER models.
+12VDC Power Supply Output for Models: DMX-6PIM, DMX-6PIM-FM
The AC-DC power supply located at the top of the enclosure is capable sourcing up to a total of
30 Watts (2.4 Amps) of power at 12VDC. Up to 24 Watts (2 Amps) may be used to power external
devices via the provided 6-pin breakaway type connector. Two (2) 1.109" knockouts (suitable for
0.75" conduit) are located on the bottom of the enclosure, and are the recommended locations
for the DC wire (conduit) entry. Unplug the breakaway connector to terminate the wires. Use a
1/8" flathead screwdriver to torque the connector terminals to the specification provided below.
Once the wire termination is complete, plug the breakaway connector back in and ensure it is fully
seated. Verify all wiring terminations and secure the lid before powering up.
Breakaway Type Connector Wire Termination
• Terminate to +12VDC and COMMON on the J9 connector.
• Use wire size #28 to #12 AWG copper wire only, rated for 167°F (75°C) minimum.
• Strip insulation length to 0.3" (7.5mm).
• Torque connector terminals to 3.6 IN-LBS (0.4 NM).
NOTE: Ensure external devices do not exceed the maximum combined current draw of 2 Amps.
