DMX Merger PCB  is a 2 in 1 out DMX 512 merger PCB with versatile uses. Merge or combine two DMX 512 signals or universes into one universe, by a selected mode type: HTP (Highest Takes Priority), Append, or Backup. Features LED indicators for power and the two inputs. Multiple merger PCB’s can be combined to merge more than two universes or provide multiple functions by configuring several PCB's in different mode types, each can perform a specific of task. For example, one could be configured to merge two or more universes into one universe, the combined output could be appended to another universe, and then the final output could operate in parallel with a backup DMX 512 source with auto switch over.

Dimensions: 1.3" Length x 3.4" Width x 1" Height (including standoffs)

DMG Selectable Modes:

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 DMX512  packet and the B input is the 2nd part of the transmitted output. In this mode two lighting boards (or any two DMX512 generating devices) can be combined, each controlling different equipment but on one cable (or universe). This mode is useful for controlling different DMX512 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 DMX512 signal. If input A’s signal fails input B will be switched to automatically and transmitted.
