Relaying DMX control data to other PSUs
Exterior 50 & 100 PSUs can be interconnected using DMX cable in a
chain to continue the DMX data link.
To extend the DMX data link from one Exterior 50 & 100 PSU to another:
1. Obtain a suitable length of DMX cable to use for data throughput.
2. See Figure 11. Prepare the DMX data throughput cable for connection
to the first PSU by stripping the last 60 mm (2.4 ins.) of the outer cable
jacket. Strip the last 10 mm (0.4 ins.) of the data ground/common, the
data +ve (hot) and data -ve (cold) wires. The use of ferrules (I-type
end caps) is recommended.
3. Install the DMX data throughput cable in the first PSU using
”Connecting a PSU to DMX control data” starting on page 34 as a
guide. Use the cable gland marked
DMX Line 2
for data throughput
cable exit from the PSU.
4. Run the data throughput cable to the next PSU and install it as if it was
a DMX data input cable using ”Connecting a PSU to DMX control
data” starting on page 34 as a guide. Use the cable gland marked
DMX Line 1
for data throughput cable entry into the PSU.
5. If you need to continue interconnecting other PSUs in a daisy-chained
DMX link, use the instructions above as a guide.
