DMX/RDM Hub
User Manual
OVERVIEW
The Pathway DIN 8-port RDM Hub (PWREP DIN P8 RDMHUB) brings flexibility to
single universe DMX512 distribution systems.
Through the use of automatic DMX512 sensing across four operating modes, any
port may detect a roving DMX512 source and act as an input; two inputs may be
merged
together; 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 P8 RDMHUB DMX/RDM Hub 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 P8 RDMHUB will operate on a range of voltages from 24-48 volts
DC, with a maximum power consumption of 7 Watts. Observe the correct polarity
when wiring the power IN terminal plug. The earth ground terminal must be
connected to the enclosure’s chassis or electrical ground terminal to improve
EMC compliance.
DMX512
DMX512 (DMX) 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 P8 RDMHUB is auto-terminated as required by its operation.
STATUS INDICATORS
PORT LEDs| Amber. 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 indicates no DMX source.
OUTPUT| Green. Steady glow indicates port is transmitting DMX. Input and
Output off on all ports indicates no DMX source.
FUNCTION| Amber. Steady glow indicates the current operating mode. Flashing
indicates the module is in edit mode.
CONFIGURATION
To configure, press and hold the Mode selection button until the current Function LED begins to flash. Momentarily release and then press the button again to cycle through the operating mode options. 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 P8 RDMHUB DMX/ RDM Hub. When no
DMX is present, the Hub will scan all ports looking for an input signal. Once
a DMX input is detected, that port becomes the input and the other 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 PWREP DIN P8 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: RDM A/B
Allows the user to select input on Port B over Port A, using amaintained dry
contact closure between COM (pin 3) and A/B (pin 1) of the three-position
contact closure terminal block. Ideal forselecting a backup console over the
primary console or source, on the fly.
Ports A and B are wired to DMX sources. All other ports are outputs.With no
connection between COM and A/B, input signal on Port Awill be output, and any
input on Port B will be ignored. When a dry contact is closed and maintained
between COM and A/B, input signalon 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 DMXwill be
output by the card. While in RDM A/B mode, the PWREP DIN P8 RDMHUB acts asan
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.
Ports are wired to DMX sources as desired, with Port A having highest priority
and Port H lowest. When signal ceases on Port A (or whichever port is
currently the active input), after a one second delay, the card will latch to
the next lower active source and distribute this source to all other ports.
Should signal return on Port A , or any other port higher than the current
input, the card will immediately latch to that source and distribute the
signal to all other ports.
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 P8 RDMHUB when in Priority mode. Intermediate devices will not
function correctly should a different DMX source have priority.
While in Priority mode, the PWREP DIN P8 RDMHUB acts as an RDM responder.
However, all RDM communication with downstream devices are 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, it allows use of a remote controller while the main
console is also active.
All DMX lines are wired back to the RDM Hub. With one DMX input active, the
RDM Hub will scan the remaining ports looking for an additional input signal.
When found, the Hub will latch to the second signal and begin merging the two
sources. When the secondary source ceases, merging will stop and the card will
begin scanning again.
NOTE: Should more than two DMX inputs be active, the sources actually
merged will be determined using the Priority Mode orderof-precedence. While in
Merge mode, the PWREP DIN P8 RDMHUB acts as an RDM responder. However, all RDM
communication with downstream devices are disabled. Any connected downstream
RDM devices will not be discovered and cannot be configured.
RDM PROPERTIES
The PWREP DIN P8 RDMHUB DMX/RDM Hub 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 P8 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, output may be held for zero
seconds, thirty seconds, 1 minute, 5 minutes or forever. Default is zero
seconds.
DMX512 Output Speed: The DMX output frame rate may be set to: Slow,
Medium or Fast. Default is Fast.
