Product Description
Doug Fleenor Design 221E-TB DMX Combine Unit - 2-Inputs - 1-Output - Terminal Blocks
The DMX512 Combine unit solves the problem of combining multiple DMX input signals into a single DMX output signal. The most common configuration of the unit allows two consoles to control a single set of dimmers in a highest takes precedence or pile on mode. Examples of where this might be necessary include booth console/stage manager's console, primary console/backup console, and where one console controls intensity of a moving light fixture while a second console is used for color and/or position. Units with up to six inputs are available. More than six inputs can be accommodated using a Master/Slave arrangement.
Units that patch and/or route the DMX dimmer channels are available for applications where two consoles control a single dimmer rack with loads in separate rooms. Such units prevent the operator in room "A" from bringing up the lights in room "B".
The DMX512 Combine Unit is based on a 20 MHz high performance microcontroller. The program is written in assembly language for maximum speed. The unit accepts any DMX signal: DMX512, DMX512/1990, 4 or 8 uS mark-after-break. The unit may be ordered to accept Colortran Multiplex on one or both inputs allowing the Unit to serve as a CMX to DMX combiner/converter. The unit may be ordered to output Colortran Multiplex allowing the Unit to serve as a DMX to CMX combiner/converter.
