DMSC OVERVIEW
The DMSC is a DMX multi switch (station or panel) controller that stores DMX scenes and allows them to be
recalled with mechanical switches of any type: 2 way, way, 4 way, or toggle switches. The DMSC has 1 DMX input
and 1 DMX output, 4 switch inputs. Each switch represents a pre stored static scene and will turn on or off the output
levels of the respective scene. The DMSC scenes can easily be recorded from the front accessible PGM button(s).
Parameter settings and options are setup by PCB dip switches, see the [PCB Dip Switch Settings] page. A DMX status
LED is used to indicate valid DMX (full on), DMX error (1x blink continues until reset), RDM or non zero start code (2x
blink/flash). Note: The D SC indicates RD data but does not pass or receive RD data.
See the LED Blink Rate Chart for
blink definitions.
 Store up to 4 static scenes and recall with the flip of a switch from anywhere and multiple locations
 Recall scenes by any style switch such as: 2 way, way, 4 way, or toggle
 OVERRIDE or MERGE the input DMX with the switches (If DMX is present on the input the switches/scenes are
optionally overridden and ignored)
 Pre stored scenes merge/combine via HTP (Highest Takes Precedence)
 Optional 5 second transition (fade) times
 Optional DMX Loss Directive, either transition to the switch/scene(s) or shut off
 Optional - Input Switch 4 as a DMX Input disable switch
 Easy set up with internal dip switches
Each preset scene can be HTP (Highest Takes Precedence) merged with other scenes and optionally merged with
the incoming DMX input (if applicable). With custom designs each DMSC DMX output can be merged with other DMSC
units or other DMX Merger units to offer custom and flexible output options.
CONNECTION
Optionally connect a DMX source into the input connector (5 or pin). If there is a DMX loop thru connector insure
that it is properly terminated locally or at the end of the daisy chain. (If there is not a loop thru connector the unit is
internally terminated). The DMX output connector will source up to 2 DMX devices (depending on the devices and
configuration). Connect the switch wiring as indicated by the legend on the back of the unit and the configuration
examples. For the switch selection any type 12VDC or higher rated switch may be used. DO NOT CONNECT 120VAC
TO THE INPUT OF THIS UNIT. The 12VDC source is provided on pin 5. Solder/connect the switch return wire(s) 1 to
pin 1, switch 2 to pin 2, switch to pin and switch 4 to pin 4 as applicable for your unit and installation. If you have an
8 input or higher unit also connect the switch return wire(s) 5 ~ 8 also etc. Check for shorts and wiring errors before
powering the unit. Mate the DB9 connector(s) and test operation. For more connection information of the DMSC, see
the DMSC Conne tion Examples.

PCB DIP SWITCH SETTINGS
Set the dip switches for the desired operation and RESET POWER to activate the new settings.
To access the dip switches, remove the front cover if applicable (silver box - remove the 5 outer screws, DIN box -
remove the 4 silver outer screws, 2 RU module - remove the respective module by removing the 4 black outer screws,
1 RU enclosure - remove the enclosure from the rack and on the rear remove the two plastic retaining clips and slide
off the top cover).
Dip Swit h 10 is not used
D.S. 9: - SWITCH 4 - DMX INPUT DISABLE - Changes the operation of SWITCH 4 to a D X input disable switch.
If DIP SWITCH 9 is OFF: Input Switch 4 is a standard scen e recall switch.
If DIP SWITCH 9 is ON: Input Switch 4 acts as a DMX input disable switch. If Input Switch 4 is off Input Switches 1- operate
normally. If Input Switch 4 is on any DMX input is ignored allowing Input Switches 1- to operate r egardless if DMX is present.
e.g. If activated/desired, input Switch 4 could be located near the lighting control area to contro l wall switch activation.
Dip Switch 9 OFF - Input Switch 4 is a standard scene switch (DMX will operate as normal)
Dip Switch 9 ON - Input Switch 4 re-purposed for DMX Input Disable
Input Switch 4 OFF: with valid DMX Input Switches 1- respond in normal operation
Input Switch 4 ON: DMX Input is disabled/ignored, Input Switches 1- operate regardless if DMX is p resent.

D.S. 8: - SLIDER/POT (POTENTIOMETER) AUTO STABILIZE - This setting is for pot/slider units and does not apply for ‘Switch’
equipped units. This setting will activate the auto stabilize routine preventing small variations in the DMX levels typical with analog
potentiometers. DMX level changes of +/- 2 are ignored. Useful if small changes aren’t desired.
Dip Switch 8 OFF - AUTO STABILIZE is OFF
Dip Switch 8 ON - AUTO STABILIZE is ON

D.S. 7: - OVERRIDE SCENE(s) or MERGE/COMBINE with DMX INPUT - IF DIP SWITCH 7 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
disconnecting or unplugging the DMX input. IF DIP SWITCH 7 IS ON = [MERGE] - The merge/com bine setting will
merge/combine all enabled scene(s) with incoming DMX. NOTE Dip Switch 6 must be OFF for this setting to be active.
Dip Switch 7 OFF - DMX Input will OVERRIDE all switches
Dip Switch 7 ON - DMX will MERGE with enabled switches

D.S. 6: - DMX LOSS DIRECTIVE - If DMX is lost or no DMX is present on the input this setting determines the output of the DMX
output of the DMSC unit. NOTE If ON then Dip Switch 7 must be ON or the switches and scenes are disabled.
Dip Switch 6 OFF - Transition/fade to switch/scene(s)
Dip Switch 6 ON - DMX output is turned off

D.S. 5: - 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.
Dip Switch 5 OFF - Transition/fade rate = 5 SECONDS
Dip Switch 5 ON - Transition/fade rate = IMMEDIATE

D.S. 1 ~ 4: SWITCH / SCENE DISABLE - Disable or enable respective switch/scenes and up.
Dip Switch 1 ON - Disable Switch/Scenes 1, 2, , and 4 (ignore dip switches 2, and 4)
Dip Switch 2 ON - Disable Switch/Scenes 2, , and 4 (ignore dip switches and 4)
Dip Switch ON - Disable Switch/Scenes and 4 (ignore dip switch 4)
Dip Switch 4 ON - Disable Switch/Scene 4

Plan all D X changes carefully, understand how each mode will respond, and thoroughly test each device after any configuration c hanges.
To abort any settings while in the programming mode, toggle the power to reset the unit, or wait 30 seconds for auto abort.

SCENE RECORDING
NOTE: If Dip Switch 7 ( erge) is on, upon entering the PG Scene Recording mode, all switch settings will be turned
off while programming and will resume upon exiting. To prevent a blackout, preset a D X scene before entering the
PG Scene Record mode.
1. Insure a valid DMX signal is present indicated by the DMX input LED on.
2. Preset a desired look from the DMX lighting board or DMX generating device.
3. Enter the PGM Scene Record Mode: Press and hold the PGM button for seconds, the 1st scene will be selected
and will blink at a 1x rate. (NOTE: If Dip Switch 7 [D X/Switch erge] is ON - Switches will be temporarily disabled and
turned off while in the PG Scene Record ode.)
4. Select the desired scene to record by tapping the PGM button until the desired scene LED is blinking, (to exit the
record scene mode tap 4 times).
5. Press and hold the PGM button seconds to confirm selection, the scene LED will blink at the 2x rate. (To exit the
scene record mode tap the PGM button.)
6. Insure the scene (seen in real time) is the desired ‘look’ to be recorded, make any changes from the DMX lighting
board or DMX generating device.
7. Press and hold the PGM button for seconds to record the scene. Two flashes on the respective LED will indicate
confirmation of the record. To abort storing, tap the button for 1 second and release.
Repeat steps to record each scene.
While in the scene record mode inactivity for 30 seconds will automatically cancel and exit.
