PWREP DIN P3 RDMHUB
DMX/RDM Merger
Manual
OVERVIEW
The PWREP DIN P3 RDMHUB DMX/RDM Merger allows merging and switching between
two DMX sources in a one-universe system.
Through the use of automatic DMX512 sensing, across four operating modes, any
port may detect a roving DMX512 source and act as an input while the other two
Port output
the single; or two inputs may be merged together; or the user may select
between inputs, or a priority scheme may be invoked. The module is RDM
discoverable and configurable, as well as daisy-chainable.
CONNECTIONS
The PWREP DIN P3 RDMHUB DMX/RDM Merger features terminal strips that can be
removed from the card to facilitate easy wiring installation or replacement.
Make the following connections, WITH
THE POWER TURNED OFF.
POWER
The PWREP DIN P3 RDMHUB will operate on a range of voltages from 24-48 volts
DC, with a maximum power consumption of 5 Watts. Observe the correct polarity
when connecting V+ and V-. The earth ground terminal must be connected to the
enclosure’s chassis or electrical ground terminal to improve EMC compliance.
DMX512
DMX512 connections consist of a shield and data pair. Connect DATA+ and DATA-
to D1+ and D1-. Observe the same polarity convention throughout the system.
Connect the cable shield or common wire to the SHLD COM terminal.
DMX TERMINATE
Each port on the PWREP DIN P3 RDMHUB is auto-terminated as required by its
operation.
STATUS INDICATORS
POWER| Red. A steady glow indicates each port’s isolated power supply is OK;
off indicates no power. If all LEDs are off, check that the module is
receiving power.
---|---
INPUT| Amber. Steady glow indicates port latched to active DMX source. Input
and Output off on all ports indicate no DMX source.
OUTPUT| Green. A steady glow indicates the port is transmitting DMX. Input and
Output off on all ports indicate no
DMX source.
FUNCTION| Red. A steady glow indicates the current operating mode. Flashing
indicates the module is in edit mode.
CONFIGURATION
To configure, press and hold the function button until the current function LED begins to flash. Momentarily release and then press the button again to cycle through the operating modes. Once the desired mode is selected, release the button. After three seconds, the LED will change to a steady glow and the new mode will take effect.
OPERATING MODE: RDM HUB
Detects and latches to a DMX input applied to any port. Ideal when a single
console or controller is moved between multiple locations in a venue. All DMX
lines are wired back to the PWREP DIN P3 RDMHUB DMX/ RDM Merger card. When no
DMX is present, the Merger will scan all ports looking for an input signal.
Once a DMX input is detected, that port becomes the input and the other two
ports become DMX outputs. If a second DMX source is applied to another port,
that source will be ignored until the initial source is disconnected. While in
RDM Hub mode, the Merger card acts as an RDMresponder and splitter. Any
connected downstream RDM devices may be discovered and configured using an
RDM-enabled console or other RDM controller.
OPERATING MODE: RDM A/B
Allows the user to select input on Port B over Port A, using a maintained dry
contact closure between COM (pin 3) and A/B (pin 1) of the three-position
contact closure terminal block. Ideal for selecting a backup console over the
primary console or source, on the fly. Ports A and B are wired to DMX sources
while Port C goes to the lighting system. With no connection between COM and
A/B, the input signal on Port A will be output, and any input on Port B will
be ignored. When a dry contact is closed and maintained between COM and A/B,
the input signal on Port B will be output, and any input on Port A will be
ignored. The switch between sources is immediate.
NOTE: If there is no DMX signal on the selected input port, no DMX will
be output by the card. While in RDM A/B mode, the PWREP DIN P3 RDMHUB acts as
an RDM responder and splitter. Any connected downstream RDM devices may be
discovered and configured using an RDM-enabled console or other RDM
controller.
OPERATING MODE: PRIORITY
Provides predictable signal priority arrangements of DMX sources. Ensures a
primary console will take over completely from stage management panels,
architectural controllers, and other data sources. Wire the theatrical console
to Port A and the architectural controller to Port B. When the signal ceases
on Port A, after a one-second delay, the card will switch to Port B. Should
the signal return to Port A, the card will immediately output that signal.
NOTE: The DMX source must cease entirely for priority to take effect.
Bringing all DMX levels to zero is not the same as the signal stopping or
disconnecting. NOTE: Do not install any DMX receiving devices between the
DMX source and the PWREP DIN P3 RDMHUB card when in Priority mode.
Intermediate devices will not function correctly should a different DMX source
have priority. While in Priority mode, the PWREP DIN P3 RDMHUB acts as an RDM
responder. However, all RDM communication with downstream devices is disabled.
Any connected downstream RDM devices will not be discovered and cannot be
configured.
OPERATING MODE: MERGE
Allows slot-by-slot, HTP (highest-takes-precedence) merging of two DMX
sources. For example, allows the use of a remote controller while the main
console is also active. Hook one source to Port A and one to Port B and the
lighting system is wired to Port C. While in Merge mode, the PWREP DIN P3
RDMHUB acts as an RDM responder. However, all RDM communication with
downstream devices is disabled. Any connected downstream RDM devices will not
be discovered and cannot be configured.
RDM PROPERTIES
The PWREP DIN P3 RDMHUB DMX/RDM Merger is fully compliant with the E1.20 Remote Device Management standard. Operating modes may also be set remotely using an RDM-enabled console or other RDM controller. The PWREP DIN P3 RDMHUB has two custom properties, which may only be set using an RDM-enabled console or other RDM controller. Hold Last Look: On loss of all DMX inputs, the output may be held for zero seconds, thirty seconds, 1 minute, 5 minutes, or forever. The default is zero seconds. DMX512 Output Speed: The DMX output frame rate may be set to Slow, Medium, or Fast. The default is Fast.
