This manual describes the function and configuration options for
Pathway DMX Repeater Pro (formerly Pathway RDM Repeater)
with firmware versions of 1.3.5 or higher.
The DMX512 entertainment lighting control protocol has become
accepted throughout the world as the standard for interoperability
between equipment supplied by most manufacturers. RDM or
Remote Device Management is a recent enhancement to the
DMX protocol that provides two-way communication between
controllers (such as consoles) and devices (such as scrollers and
moving lights).
We designed the DMX Repeater Pro to permit the connection of
both conventional DMX devices and RDM-enabled products.
With 8 outputs, the DMX Repeater Pro offers a number of
features, many of which are new to opto-splitters:
•
RDM Repeater: One incoming DMX data stream can be
repeated by up to eight output ports, allowing a “star” topology to
be created. Bi-directional RDM communication is supported on all
ports and is customizable on a port-by-port basis.
• DMX Repeater/Merger: Two streams of DMX can be
merged on a highest-takes-precedence (HTP) basis, and
repeated by the remaining output ports. RDM can be enabled on
a port-by-port basis.
• Hub Mode: Often console inputs are daisy-chained
together, creating an illegal DMX configuration, and the potential
for DMX signal errors. In hub mode, the DMX Repeater Pro can
direct up to 8 console inputs to up to 8 outputs without breaking
any rules and while maintaining DMX signal integrity.
• DMX Monitor and Console: A bar graph and numeric
display give you a quick indication of in-coming DMX levels. DMX
output can be generated directly from the front panel without the
need for a separate device. Both features are indispensable tools
for troubleshooting.

DMX512 – Probably the most widely used protocol for controlling
lighting and effects equipment, DMX512 was the first industry
standard digital multiplex protocol. The DMX signal consists of
512 8-bit control packets sent asynchronously over a two-pair
shielded cable at 250K Baud. DMX signal is simplex, or
