The PWREP DIN P4 RDM is internally terminated and does not require
any further termination at the device.
However, the last DMX device on each output leg must still be properly
terminated in accordance with the E1.11 DMX512-A standard, to ensure
correct device operation.
The DMX THRU connector is an active pass-through and fully supports
RDM. In eect, it is a fth output port. If power is lost to the device, the
DMX THRU connector will no longer function.
Due to timing restrictions in the RDM standard, no more than seven
(7) PWREP DIN P4 RDM devices may be daisy-chained together in
one run.
ANSI E1.20 Remote Device Management (RDM) is an open standard
data protocol that provides DMX512-A networks with the option of bi-
directional communication (aka “talkback”). By using half-duplex data
communications, RDM operates over the same wire pair (pines 2 and
3) as DMX, ensuring backward compatibility with all DMX installations.
System layout is critical for successful use of the RDM standard.
Wire type and installation methodology must be correct as the timing
restrictions required by RDM are much more strict than for DMX.
RDM devices are classied as “controllers”, “responders”, or “in-line”
devices. Only one controller may be active on a given network. When the
controller issues a command, it listens for a response within a prescribed
time. During this period, “in-line” devices like the PWREP DIN P4 RDM
prepare to pass data back to the controller.
Due to timing constraints imposed to ensure integrity of the DMX signal,
a maximum of seven in-line devices are allowed between the controller
and an output with a responder attached.
The PWREP DIN P4 RDM is considered an “in-line” device. The signal
path may never include more than seven DIN splitters. Anything greater
will prevent devices further downstream from being able to respond.
WARNING: DO NOT install other RDM responders
between the controller and the PWREP DIN P4
RDM, or between the THRU connector on one DIN
device and the DMX IN on the next.
