DMX Interface - PWINF DIN PWM4A / PWM6A
6-Channel PWM DC Dimmer
Manual
08/31/21
The Pathway eDIN LED Dimmer/DC Driver provides DMX512
control over LEDs and other DC devices. Each module
provides 6 channels of control. When controlling LEDs, the
module acts as a dimming interface only. The LED fixture
will require a separate regulated DC power supply, as
recommended by its manufacturer.
These instructions apply to REV 2 hardware running
firmware 1.6.2 or higher.
The PWINF DIN PWM 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
, and
observe ESD precautions by ensuring the installer is properly grounded
before handling the device.
POWER
The DMX/RDM Splitter is designed to run on a range of voltages from
9-30 volts DC. Each PWM DC Dimmer requires 5 watts. Observe the
correct polarity when connecting to V+ and V-.
A second set of terminals are provided as a DC power-through
connection to other DIN devices. The EARTH GND terminal may be
connected to the enclosure’s chassis or electrical ground terminal to
improve EMC compliance.
DMX512
DMX connections consist of a shield wire and one or two data pairs.
DMX IN is wired from the control console, or other source. DMX THRU
may be daisy-chained to the DMX IN of other eDIN cards, or to other
DMX equipment.
Connect DATA+ and DATA– wires to D1+ and D1- respectively. The
optional data pair may be connected to D2+ and D2-. Observe the same
polarity convention throughout the system. Connect the shield wire to
the SHLD/COM terminal.
DC/PWM OUTPUTS
The LED Dimmer/DC Driver interface provides six (6) outputs that will
each handle up to 4 amps at voltages up to 30VDC. The outputs are
of the current-sinking type. A separate DC power supply is required,

STATUS INDICATORS
appropriately sized for the connected load, as recommended by the
connected equipment’s manufacturer.
Each output is fully opto-isolated from the other outputs, from the
DMX signal and from the eDIN board power supply. Multiple pins
are provided to allow for load spreading. Outputs are connected
as follows:
LOAD-
(Terminals 1 & 2): Connects to the negative terminal of
the load, or the LED Cathode.
V-
(Terminals 3 & 4): Connects to
the negative or common terminal
of the load power supply.
V+
(Terminals 5 & 6): Connects
to the positive terminal of the load
power supply and to the positive
terminal of the load, or the LED
Anode.
