The DM-2512R DMX Merger from Elation Professional as the name implies, merges two DMX signal inputs, to one output. Three operation modes can be selected by using the 2 DIP switch setting.
The three operation modes include HTP (Highest Takes Priority) mode, Backup mode and Merge mode. When set to HTP mode, the controller with the highest channel output setting will take priority on output. HTP is most commonly used with controller dimmer channels. When set to Backup, a controller that is connected to the B input is on standby and will only take precedence if the controller connected to the A input fails. When set to Merge mode, controller signals coming into input A and B will merge to one output.
Ten-position DIP switches are available so the starting DMX address channel can be set for the controller that is connected to input B. For example, with a Stage Desk 16 that is connected to input A, we would patch the controller that is connected to input B at channel 17 and also set the binary address on the DM-2512R to 17.
