DMX Cable Preparation and Termination
This instruction assumes preparation of Belden 9729 (or equivalent) cable for termination to the
three-position screw terminal connector provided.
Note:
Not for use with Cat5, Cat5e, or Cat6 cable. When running DMX with these
cable types, use the 3-position IDC connector.

1. Leave approximately 20 cm (8 in) of wiring to allow slack
for future service needs.
2. Strip 18 cm (7 in) off the outer jacket.
3. Label the cable with the data type and run designation.
(DMX1, DMX2, etc.)
4. Strip the foil shielding from each wire set to within 6 mm
(1/4 in) of the outer jacket.
5. Untwist the shield wire from each pair and apply a piece
of 1.6 mm (1/16 in) clear heat shrink to each shield wire.
6. Twist each shield wire back onto its data pair, and then
apply a 4 cm (1.5 in) piece of 0.5 cm (3/16 in) heat shrink
all the way down each 3-wire set. Make sure to capture
the foil shielding at the base.
7. Apply the 5 cm (2 in) piece of the 1 cm (3/8 in) heat
shrink, centered on the end of the cable jacket and the
bases of all the wires in the cable.
8. Cap the ends of the unused pair of wires with a 2.5 cm
(1 in) piece of 0.5 cm (3/16 in) heat shrink centered over
the end of the wires.
9. Strip 6 mm (1/4 in) of insulation from all of the wires to be
used.
10. Maintain the wire pair twist as close to the screw terminal
connector as possible and terminate the wires.
•
Insert the data - wire (typically black) into the terminal
labeled “DMX -” and secure.
•
Insert the data + wire (typically red or white) into the
terminal labeled “DMX +” and secure.
•
Insert the common (shield) wire into the terminal labeled
“DMX " and secure.
11. Bend back the unused set of wires and secure them to the cable with a wire tie.
12. Secure the terminated wire sets together with a wire tie 5 cm (2 in) from the connector.
Terminate DMX In and DMX Thru
1. Run your DMX lines through the other previously installed screw-clamp conduit connector
and terminate the RJ45 connectors to the DMX In and DMX Thru terminals accordingly.
2. Terminate DMX/RDM data signal for the last DMX/RDM device in the data run by sliding the "DMX_TERM"
switch to the "ON" position (in the direction of the arrow in the illustration at
DMX Terminal Blocks on the previous page
). All other devices in the data run maintain the
factory default termination switch setting (not terminated).
3. Reinstall the driver cover using the two previously removed screws.
