Safety Notes
Install in a dry sheltered position
Ensure adequate ventilation
Installation should only be performed by a qualified professional
Install in accordance with all appropriate wiring standards
Never connect a LED fitting to a driver that is powered. Doing so may result in damage to the
LED.
Always make sure the output voltage range and output current of the LED driver match the
requirements of the LED fitting. Failure to do so may result in damage both the driver and
fitting.
Introduction
The LDMX-PWM-4 (Figure 1) is a
DMX receiver with three channels
of PWM
driven outputs for controlling 4
channel LED fittings, such as
Digilin’s PaletteFlex RGBW LED
Strip. The PWM outputs make
use of Digilin’s special smoothed
PWM transitions software making
variations in light output almost
imperceptible even at low levels.
In addition to DMX input, the LDMX-
PWM-4 also has a connector for direct interfacing to Digilin’s Colour Theme Controller, making a
complete system simple to install and control.

Installation
Connections
Figure 2 shows the connections on
the LDMX-PWM-4. 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-4 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.

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-4 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-4 has a 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-4 outputs will be set at 50% for all channels at start-up and loss of DMX
signal.
