DMX Cat5 Preparation and Termination
This instruction assumes use of Cat5 (or equivalent) cable for termination to the three-position
Cat5 insulation displacement connector (IDC) provided in the termination kit.
1. Follow normal Cat5 wire installation procedures to remove 5 cm (2 in) from
the end of the cable jacket.
2. Separate the White/Brown, Orange, and White/Orange conductors from the
cable. These conductors are required for DMX out.
3. Cut the remaining unused conductors from the cable flush to the cable jacket.
4. Label the cable with the data type and run designation (for example D1 for
DMX run 1).
5. Untwist 25 mm (1 in) of the White/Orange and Orange conductors, and then
insert the conductors through the labeled terminals as follows:
Common (White/Brown) to terminal 1
•
Data - (Orange) to terminal 2
•
Data + (White/Orange) to terminal 3
•
6. Fully depress each terminal, closing it onto the wire.
7. Use side-cutters to trim the excess wire from the connector.
