UMX – 24 DMX/LMX to ANALOG TRANSLATOR
Revision 0.3 OWNERS MANUAL 07/27/2005
DESCRIPTION
The UMX-24 is a very compact lighting protocol translator which receives a USITT DMX-512 signal or a LMX-128
multiplex signal from a lighting console. The unit converts the incoming signal, and transmits it as 24 channels of
0–10 volt analog signals. A “passthrough” DMX and LMX connector are provided. The unit is powered by an
external 13VAC power supply which is provided.

FACTORY CONFIGURATION OPTIONS
The unit can optionally be supplied to output 0 to +15 VDC analog or 0 to +20 VDC analog.
CONNECTIONS
DMX INPUT CONNECTIONS
Connect the output of the console to the 5 pin male XLR connector on the rear of the UMX-24. The female 5 pin
XLR connector on the rear of the unit is a “passthrough” connector to connect the DMX signal to other equipment.
DMX TERMINATION
The left most DIP switch on the front of the unit applies a DMX termination when in the down position. A DMX line
should be terminated at the last DMX device (and ONLY the last DMX device) on the chain.
LMX INPUT CONNECTIONS
Connect the output of the console to the 3 pin male XLR connector on the rear of the UMX-24. The female 3 pin
XLR connector on the rear of the unit is a “passthrough” connector to connect the LMX signal to other equipment.

UMX – 24 DMX/LMX to ANALOG TRANSLATOR
Revision 0.3 OWNERS MANUAL 07/27/2005
ANALOG OUTPUT CONNECTIONS
The 25 pin (DB-25) D connector on the front of the unit is for the analog output signals which are to be connected
to the analog dimmers or other analog compatible lighting devices. Pin 1 of the DB-25 connector is the channel 1
output signal. Channels 2 through 24 follow in sequence (pin# = channel#). Pin 25 is the common or signal
ground.
OPERATION
The red LED indicator on the front panel lights when power is applied to the unit. The green LED on the rear of
the unit is lighted when a valid input signal is present.
The unit may be set to operate any range of 24 channels up to 512 by setting DIP switches on the front of the
unit. A table at the back of this manual shows DIP switch address settings.
The 2nd from the left DIP switch operates a hold function. If this switch is set to UP and the incoming signal is
removed – the unit will continue to send the last valid channel information to the dimmers.
If both DMX and LMX input signals are present, the DMX signal will be used and the LMX signal will be ignored.
The UMX-24 will not convert DMX to LMX or convert LMX to DMX.
TRIM ADJUSTMENT
A output level trim adjustment is accessible via a hole in the front panel. If you connect a dc voltmeter to any of
the analog outputs - you can then adjust the output level. The adjustment is applied to all channel outputs.
EXTERNAL POWER SUPPLY INFORMATION
Input Voltage: 120VAC
Output Voltage: 13.5 VAC
Output Current: 800 Milliamps
Connector: 2.1mm female connector
The UMX-24 will operate using an alternative external power supply which can provide anywhere from 13 to 24
Volts AC or DC. The supply must be rated at 600 ma. If a DC supply is used, the center pin of the connector
MUST BE THE NEGATIVE output terminal of the supply.
MAINTENANCE
TROUBLESHOOTING
9 Check the connections and integrity of the associated cables (a very common source of problems).
9 Ensure that the dimmers are on and operating. Verify that the dimmers addressing is correctly set.
9 Check the address settings on the UMX-24.
REPAIR
There are no user serviceable parts in the unit. Service by other than Lightronics authorized agents will void the
warranty. If service is required, contact the dealer from whom you purchased the unit or contact Lightronics.

ADDRESS SETTINGS TABLE
The DIP Switch Setting column shows the positions of the DIP switches on the UMX-24. The Start Channel
column shows the resulting DMX/LMX channel assignment for the first analog output channel (channel 1). The
left end two DIP switches are not included in the table since they do not affect the address settings.
NOTE: Some control consoles and dimmers can be programmed or "patched" to alter their channel order. You
may get unexpected results if you are not aware of the patch condition when you set the address switches.
EXAMPLE: If the UMX-24 DIP switches are set to ШШГШГШГГ : the first channel of the dimmer will respond
to console channel 87. The remaining dimmer channels will respond to console channels 88, 89, 90, …etc.
