DMX 512 Merger - Merge 2 or 3 DMX universes into one universe with this multifunction merger unit. This easy to use merger has versatile functions, and several mode types to choose from: HTP (Highest Takes Priority), Append, and Backup.

NEW - The DMX Merger now has an internal power supply, an optional 3rd input, and Neutrik XLR Connectors. As an option a 3rd input can be pre installed or it can be added later. By adding a 3rd input you can increase the merging sources and adds an additional function. For example merge two inputs w/ HTP and then append or backup w/ a 3rd DMX source.

The 3rd input kit includes a Merger PCB, one Neutrik 3 or 5 pin connector, and mounting PCB hardware.

DMX Merger Examples: Merge a DMX console with a computer DMX controller, append two DMX consoles' outputs, or backup your show with two DMX generating sources with auto switchover function, as several possibilites. Multiple merger / combiners can be used to merge more than two universes or provide multiple functions.

Available as a PCB, 1RU rack mount, or 2RU modules, with 2x1, 3x1, 4x1, and 5x1 options
 
Dimensions: 3.7" x 6.7" x 2.1"

DMX MERGER SELECTABLE MODE TYPES:

3rd INPUT OPTION If the 3rd or “C” input is installed, the merged output of A and B inputs are connected to the ‘A’ input of a 2nd merger DMG-PCB (Printed Circuit Board). The 2nd merger PCB can have a different mode type (listed below) than the 1st merger PCB. All of the A and B rules listed below for each mode type apply accordingly.

MERGE HTP MODE The HTP mode will merge two universes into one universe using HTP (Highest Takes Priority) processing of the level of each channel. In this mode two lighting boards (or any two DMX 512 generating devices) can control the same devices. This mode is useful for controlling the same DMX 512 equipment and devices with two DMX 512 generating devices in one universe.

APPEND MODE The Append mode will append input B after input A, input A is the 1st part of the DMX 512 packet and the B input is the 2nd part of the transmitted output. In this mode two lighting boards (or any two DMX 512 generating devices) can be combined, each controlling different equipment but on one cable (or universe). This mode is useful for controlling different DMX 512 equipment or devices with two DMX 512 generating devices in one universe.

BACKUP MODE The Backup mode will transmit input A continuously, ignoring input B as long as input A is a valid DMX 512 signal. If input A’s signal fails input B will be switched to automatically and transmitted.
