Pathway 1008 User Manual

Model 1008 LED Dimmer

OVERVIEW

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 modules.

CONNECTIONS

eDIN LED Dimmer/DC Driver modules feature terminal
strips that can be removed from the module to facilitate
wiring and replacement. Make the following connections

WITH THE POWER TURNED OFF:

POWER

The module is designed to run on a range of voltages
from 9 to 30 VDC, at 500mA per card connected.
Observe the correct polarity when connecting to V+
and V-. A second set of terminals is provided on the
same connector to daisy-chain power to other eDIN mod­ules. Earth Ground must be connected to the enclosure’s
chassis or ground terminal to ensure 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 D1­respectively. 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, appropriately sized
for the connected load, as recommended by the con­nected equipment’s manufacturer.

REV 2

Manual

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.

‘DMX PRESENT’ RELAY CLOSURE

Wire RCOM to RNC or RNO for a normally closed or
normally open DMX indicator, as desired.
When DMX is present, the closure will be held in a
state opposite to its ‘normal’ position.

CONTACT CLOSURE ‘PANIC’ INPUT

When CCL is shorted to IN-GND, for example by clos­ing an e-stop switch, all outputs are forced to the MAX
output level, regardless of DMX level or signal presence.

ANALOG INPUT

Applying a 0-10VDC input between any AIN(x)
and the IN-GND pin will drive that particular output. Out­put level is an HTP-merge between the DC voltage level
and the incoming DMX signal for that channel.
Do not exceed 10VDC maximum input voltage.

LED Dimmer/DC Driver Configuration

CONFIGURATION

The eDIN user interface has 2 operating modes: Function
and Edit. Press the ▲ or ▼ buttons to select a function,
as indicated by the LEDs next to ADDRESS, MODE,
UTIL, and TEST. Once selected, press and hold the
ENTER button until a dot appears in the lower right-hand
corner of the display. The card is now in EDIT mode.
Use the ▲ or ▼ buttons to change, then press ENTER to
accept the new value.

SET DMX ADDRESS

Once in ADDRESS edit mode, press ▲ or ▼ to change
the start address to the desired value between 1 and 512.
Press ENTER to save the new start address.

SET OPERATING MODE

Mode 1: Default LED Control Mode
(6 channels)

The incoming DMX channel level is interpolated to pro­duce a 16-bit value. A weighted fade curve is also applied
to compensate for LED response, producing an appar­ently linear fade to the human eye.

Mode 2: DMX Double Precision Mode with Curve
(12 channels)

Two DMX control channels are used to produce a 16-bit
value for each output. A weighted curve is also applied .

Mode 3: DMX Double Precision Mode without Curve
(12 channels)

Two DMX control channels are used to produce a 16-bit
value for each output with no compensating curve. Output
follows the DMX values linearly.

Mode 4: Non-Dim Mode

When the DMX channel is below 50%, the corresponding
output will be off. When the channel level is above 50%,
the corresponding output will be on (full). Use for non­dimming loads such as solid state relays or solenoid coils.
Mode 5: Single channel control
One DMX channel, the start address, controls all six out­puts from the module.

Mode 6: 3 Channel Mirror Mode with Curve
(3 channels)

Outputs are paired (1/4, 2/5, 3/6). Paired outputs are
driven by the same DMX channel, with the weighted
curve applied to the output.

Mode 7: 3 Channel Mirror Mode without Curve
(3 channels)

Outputs are paired (1/4, 2/5, 3/6). Paired outputs are
driven by the same DMX channel, with no compensating
curve. Output follows the DMX values linearly..

UTIL MODE

There are four UTIL modes.
A: Adjusts the smoothing algorithm between 1 (very

smooth) to 100 (no smoothing). Factory default is 64.

B: Adjusts a Grand Master maximum output level be-

tween 0 (off) and 256 (default).

C: Sets a MIN output level between 0 and 255, that the

card will always output even in the absence of DMX.

D: Sets DMX signal loss behavior. Options are “0” - zero

seconds, “0.5” - thirty seconds, “1” - one minute, “5” ­five minutes and “--” forever (default).

TEST MODE

Use ▲ or ▼ to cycle the display from 1 through 6. The
corresponding output will be at full. Normal DMX input
will be ignored. Press ENTER to exit test mode.

STATUS INDICATORS

POWER IN Blue. Steady glow indicates power

supply OK; off indicates no power.

PROCESSOR Green. Steady glow indicates processor

is OK; off when POWER IN is lit indi­cates processor failure.

DMX TERMINATE

DMX rules require the final device in-line have a termi­nating resistor. If there are other devices connected to
the DMX THRU terminals, the DMX TERMINATE switch
should be OFF. Otherwise the terminator should be ON.

RDM RESPONDER FEATURES

The eDIN 1008 LED Dimmer module is fully compliant
with ANSI E1.20 Remote Device Management as a re­sponder device. An RDM controller can discover and
retrieve the card’s DMX start address, firmware version
and operating mode (personality). DMX start address
and operating mode are remotely configurable by the con­troller. Starting with firmware 1.5.5, an RDM utility can
upgrade the firmware in the field.

COMMENTARY ON DIMMING LEDS

The #1008 eDIN LED Dimmer does not regulate the
current supplied to the LED. Always use a current­regulated power supply, approved by the LED manufac­turer, to supply the LED fixture.
