Using With Colour Theme Input
In order to connect a Colour Theme Controller the DMX address should be set to 1
and the Input Select Switch (switch 10 of the DMX address switch, as shown in
Figure 1) should be in the up position. When data is being correctly received, the
green LED should be on. It is possible to connect further DMX receivers to this unit.
They should be configured to operate with a standard DMX input (not a Colour
Theme Input) with the DMX address set to 1.
Using With DMX Input
In order to use the LDMX-PWM-3 with a DMX feed simply set the desired address
and connect the DMX feed to the DMX input. Remember to terminate the DMX feed
at the end of the chain with a 120Ω resistor between the DMX + & - lines. When data
is being correctly received, the green LED should be on.
Test Mode
The LDMX-PWM-3 has test mode which ramps each individual output up to full
brightness then back off in sequence. This test mode is entered by setting the DMX
address to 0 (all switches down). While in this mode, any incoming DMX data is
ignored. Once the address is changed from 0, the unit will complete the current cycle
of the test, then return to normal operation.
Fallback Output
By default, the LDMX-PWM-3 outputs will be set at 50% for all channels at start-up
and loss of DMX signal.
