Installation
Connections
Figure 2 shows the
connections on the LDMX-
PWM-3. For standard
operation, simply connect
24V to the power connector,
the led fittings to the PWM
outputs and either the Colour
Theme Controller or a DMX
source to control the light
levels.
Operation
The LDMX-PWM-3 has a single 24VDC power supply. Once it is connected, the red
power LED shown in Figure 2 will come on. If the unit is receiving good
communications, the green DMX activity LED will also be on.
Setting Address
The DMX address is set using the first 9 switches of the DMX address switch. The
address is set as a binary number (with switch 1 the LSB, Appendix A lists addresses
and their corresponding switch settings). As the unit is a 3 channel receiver, it will
respond to data in the set address, and the following 2 addresses in the DMX data
stream. Therefore, the address should not be set to over 510.
Note:
that to use a
Colour Theme Controller, the address must be set to 1.
