DIN rail DMX merger


The DmxMerger is DMX-512 merger in a DIN rail form factor. The device features six optically isolated DMX inputs and one optically isolated DMX output.

Merging strategies

The DmxMerger offers three different merging strategies.

The Latest Takes Precedence strategy selects one of the LTP inputs based on which port had the most recent change. This can be a change in channel levels or a DMX signal becoming active.

The Highest Takes Precedence strategy is used for combining the HTP inputs and the result of the LTP merging. In this strategy each DMX channel is compared across the inputs and the highest value is forwarded to the output.

If a DMX signal is present on the Priority input then this input is forwarded directly to the output. In this case all other inputs are ignored.

Data path

The Priority, HTP and LTP ports are all merged together.

Combine multiple controllers

When your DMX installation is best served with more than one controller, the DmxMerger can combine the outputs from multiple controllers into one single DMX network.

Create redundancy

Use the Priority input to connect your main DMX controller. Should it fail, the DmxMerger will instantly switch to a secondary DMX controller connector to one of the other input ports.

Combine with other products from the family

The DmxMerger can easily be combined with the CueCore2 and QuadCore lighting engines. Or the IoCore2, a GPI, GPO & RS-232 interface module. And the B-Station and Kiosc.
