DMX Merger: A one-in/eight-out or two-in/seven out
merger/opto-splitter with RDM disabled on all ports. Some older
equipment may not check the start code of a DMX packet, and
misinterpret RDM requests as level changes, leading to erratic
behavior. RDM can be re-enabled on a port-by-port basis.
While in this mode, the Repeater scans ports A through H for
active DMX. If found, the second DMX source will be merged with
the primary “DMX IN” signal on a highest-takes-precedence
basis. RDM will not work on ports that are merging DMX due to
timing constraints in the RDM protocol.
DMX Hub: An eight-in/eight-out switcher. In this mode, the DMX
Repeater Pro scans each port in turn (including the primary input
port “DMX IN”) until a DMX source is found. It then reconfigures
all other ports (except the primary input port) as outputs and
routes the DMX signal to them. If DMX signal is lost, the
Repeater will begin the scanning process all over again. This
mode allows one console to be easily moved between multiple
locations or to allow a back-up to rapidly take over from a failing
primary console.
In DMX Hub mode, active signal appearing at the “DMX IN” port
will take immediate priority over any other active signal.

Other Settings
Other global parameters available from the “Repeater
Configuration” screen (again using the up\down arrows to cycle
through the options and the check-mark to accept) are DMX
speed, hold time and the backlight brightness. These settings
apply to all ports.
DMX Speed: The speed option specifies the refresh rate or how
often the ‘dimmer’ levels are updated. The maximum DMX
refresh rate is about 44 Hertz (Hz), but some equipment behaves
erratically at that rate. The DMX Repeater Pro can operate at
three different refresh rates: slow (34 Hz), medium (39Hz), fast
(44 Hz). The factory setting is fast.
DMX Hold Time: This option determines how long the DMX
Repeater Pro will hold its ‘last look’ in the event of loss of DMX
signal. The choices are 0 seconds, 30 seconds, 1 minute, 5
minutes and Forever. The factory setting is 0 seconds.
