Often an installation requires an architectural controller and a lighting
console to be active on the same DMX universe or even to
simultaneously access different dimmers within the same rack.
Although resolvable with a merger card, the situation can become
hopelessly complicated if the secondary source must move between
numerous locations. The DMX Repeater Pro provides an elegant,
hot-patchable solution, eliminating the need for a manual DMX patch
bay.
With the architectural or non-mobile controller plugged into the main
“DMX IN” port, signal will be transmitted out the other eight ports,
which can be hard-wired to various locations around the site.
As soon as the secondary controller is plugged into one of those
locations, the DMX Repeater Pro will sense the new source, turn
that port around and begin to transmit through the other seven ports
a DMX stream that is a highest-takes-precedence merge of the two
sources. The remote receptacles can wired for in/out usage, or
simply wired as female outputs and a turnaround cable used
between the receptacle and the controller.
The ideal application for the DMX Repeater Pro’s ‘Merger Mode’ is in
installations where an architectural controller and a lighting console
must speak to the same dimmers, or where a Remote Focus Unit
must operate at the same time as the main lighting console.
