DMX Standard Wall Switch Controller User Guide
DSC5
1-4 Gang Options
DSC5 OVERVIEW
The DSC5V DMX controller uses a standard wall switch available with 1 - 4 switch(es) to
control a standard DMX lighting systems. Store up to 4 static scenes and then recall just by turning
on the respective switch. Easily turn on DMX controlled lights without having to turn on or use a
DMX lighting board or controller. For example switch 1 could be "Band Practice", switch 2 "Stage
Lights", switch 3 "Audience Lights", switch 4 "Balcony". Simply turn on any of the switches and the
pre recorded scene will turn on the DMX lights, with an optional 5 second fade. If the "Merge"
function is turned off then any DMX input will override the switches and take control allowing a
DMX controller to control the lights. Turn off the DMX controller and the switches again are
operable. The switch/scenes are HTP (highest takes precedence) merged with each other allowing
any or all switches to turn on it's respective scene. DMX scenes are easily recorded to any of the
switches from the front of the unit.
Record up to 4 DMX scenes
Optional 5 second fade up/down

CONNECTION
There are several ways the unit can be installed. Example 1 shows the unit installed as the final device before
the data is sent to the DMX dimmers and fixtures. In this configuration the final DMX signal that feeds the dimmers
and/or lights, loops through the DSC5 wall switch unit, allowing the switches to control the dimmers and/or lights.
Example 2 (see EXAMPLE 2 below) shows the unit installed as part of the DMX source by merging the DSC5 units’
DMX with any other DMX generating device(s). In this configuration the DSC5 generates a DMX signal and then is
merged with several merge options using our DMG Merger products.
In either configuration, once the DSC5 wall switch unit has the scenes recorded, the DMX input could be
removed and the unit simply generates a DMX signal to control the dimmers and/or lights in a standalone DMX
controller.

Install the appropriate DMX and power wires. Insure the path is safe and away from the public and not prone to
damage as these wires carry the DMX signals and power to/from the unit for the lighting system. It is recommended to
install inside a conduit. Connect the DMX generating device, power supply, and DMX output wires source to the
installed wires, check for accuracy, check the polarity of the power supply on both ends before applying power. Turn
the unit on and check for that the power LED is illuminated. Send DMX data, the data LED should be illuminated.
Record scenes as needed and check for proper operation.
DO NOT CONNECT 120VAC TO ANY OF THE CONNECTIONS OF THIS UNIT.
Connect DMX source wires (lighting board or similar) into the input screw terminals labeled: -2 and +3 (XLR
connector pins 2 and 3 respectively) See PCB Wiring Diagram, and WIRE Example. The input is terminated locally so
loop thru is not recommended. Connect the DMX output destination wires to the screw terminals labeled: Gnd, -2, and
+3. Connect the power supply to positive and ground wires to the PWR in terminals - CHECK POLARITY BEFORE
CONNECTING, REVERSE OR OVER VOLTAGE MAY DAMAGE THE UNIT. Once connected the power LED will
illuminate indicating power is present. Under normal operating conditions and all DMX input and outputs connected,
check the voltage at the PCB and insure that it’s in the range of 8VDC to 12VDC. This is important to insure proper
operation.

D.S. 1: - TRANSITION / FADE RATE - Sets the transition rate for switch/scene setting changes. If a respective scene/switch
is turned on or off the scene recall will either be immediate or have a 5 second transition rate.
1
Dip Switch 1 OFF - Transition/fade rate = IMMEDIATE
Dip Switch 1 ON - Transition/fade rate = 5 SECONDS
D.S. 2 - DMX LOSS DIRECTIVE - If DMX is lost or no DMX is present on the input this setting determines the state of the
DMX output of the DSC5 wall unit. NOTE: If ON then the switch outputs will not be sent unless there is DMX present on the
2
input and the unit is in the MERGE mode. Otherwise once the DMX input signal is lost the output will turn off.
Dip Switch 2 OFF - The DMX output is always on/active
D.S. 3: - OVERRIDE SCENE(s) or MERGE/COMBINE w ith DMX INPUT - IF DIP SWITCH 3 IS OFF = [OVERRIDE] setting,
all enabled scene(s) will only be active IF there is not a DMX input signal present, (either turning off the DMX lighting board or
3
disconnecting or unplugging the DMX input). IF DIP SWITCH 3 IS ON = [MERGE] - The DSC5 wall unit will merge/combine all
enabled scene(s) with incoming DMX. NOTE Dip Switch 2 must be OFF for this setting to be active.
D.S. 4: - Aux (Future Use)

Plan all DMX changes carefully, understand how each mode will react, and thoroughly test each device after any configuration cha nges.
To abort any settings while in the programming mode, toggle the power to reset the unit, and reenter if desired.

1.
Insure a valid DMX signal is present indicated by the DMX input LED on.
2.
Preset a desired scene from the DMX lighting board or DMX generating device.
3.
Enter the PGM Scene Record Mode by press and holding the Record button for 3 seconds, the data LED will blink
at the 1x rate. Turn on only 1 switch that the scene is to be recorded to, the data LED will blink at the 2x rate. Press and
hold the record button for 3 seconds, the data LED will flash 2 times indicating the scene has been recorded. To abort
recording, wait 20-30 seconds to allow the unit to time out.
Repeat steps to record each scene.
While in the scene record mode inactivity for 30 seconds will automatically cancel and exit.
