To congure, rst press the ▲ or ▼ buttons to select the
desired function, indicated by the LED next to ADDRESS,
MODE, MIN, MAX, or 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.
When done editing a parameter, press ENTER. The dot will
disappear, the new value will be saved and the unit will be ready
for operation.
Once in MODE edit, choose from the following:
• MODE 1: 0-10VDC Output (MAX will read 158)
• MODE 2: 0-5VDC Output (MAX will read 79)
• MODE 3: 0-15VDC Output (MAX will read 237)
• MODE 4: 0-2.5VDC Output (MAX will read 40)
• MODE 5: Custom D-to-A (set your own voltage)
• MODE 6: EFBC/LED Control - 10% threshold
• MODE 7: Non-Dim (see below)
• MODE 8: EFBC/LED Control - 1% threshold
To set a custom output voltage, conrm the DMX start address is set
to 1. Connect a voltmeter between output 1 and COM on the card.
Connect a DMX source to DMX IN. Using your source, vary the DMX
level on channel 1 and conrm that the voltage output is changing.
Set the DMX level to full.
Use the ▲ or ▼ buttons and ENTER to select MAX for editing.
Use ▲ or ▼ while observing the output on the voltmeter. Once the
voltage is at the level you desire, press ENTER to save. Repeat this
process to set a MIN level. Valid MIN levels are between 0 and 254.
Valid MAX levels are between 1 and 255. 255 roughly corresponds
to an output of 16VDC. Customizing these values will place the card
in Mode 5. MIN and MAX should be checked in Modes 6, 7 and 8,
with MAX set as a value of 158 to ensure proper operation of
the solid state relays.
Mode 7 provides non-dim control of solid state relays or LEDs. At a
DMX level of 0%, each channel outputs +10VDC. The output voltage
drops to zero when DMX passes 50%. All blocking diodes must be
shunted (bypassed) in this mode.
One in ADDRESS edit mode, press ▲ or ▼ to change the start
address to the desired value. Press ENTER to save the address.
Valid addresses range from 1 to 512.
Once in TEST mode, using the ▲ or ▼ buttons will toggle each
output on and o. The output number is shown on the right hand
display. DMX input is ignored while in TEST mode.
Shorting the CCL pin to COM will drive all outputs to full.
The CCL input overrides the DMX input level.
Press the ▲ button while turning power on to enter self-test mode.
All LEDs will ash sequentially. The display will cycle 0 through 9,
then show the serial number and rmware version. Cycle power to
end self-test.
The behavior of the diode shunts is dependent on the module’s
revision level .The revision number is shown on the product label,
next to the part number.
The diodes prevent the control signal from back-feeding into the
output and damaging the module. The diodes must removed from
the circuit to allow sinking control. The 16 DIP switches are wired
as shunts, allowing the diodes to be engaged or disengaged output-
by-output.
REV 4 and below: The blocking diodes are engaged by default. With
the shunt switches in the “o” position, the diodes will prevent current
backow. This is the correct arrangement for driving analog dimmers.
With the shunts in the “on” position, the diodes are bypassed. This
is the correct arrangement for sinking control of EFBCs and LED
dimmers.
REV 5 and above: The blocking diodes are bypassed by default.
With the DIP switches in the “o” position, current will backow
through the card. This is the correct arrangement to allow sinking
control of EFBCs and LED dimmers. With the DIP switches in the
“on” position, the diodes will block backow current. This is the
correct arrangement for driving analog dimmers.

Mode 6 and 8 allow unied control of up to eight circuits of LED
xtures or Mark 7-type electronic uorescent ballasts, with a
maximum of 20 xtures/ballasts on each circuit. Two channels are
used for each circuit. Channels are paired: 1 with 9, 2 with 10, and
so on.
The lower channel provides 0-10VDC dimming control, while the
higher acts as a non-dim, when connected to a solid state relay
controlling the circuit’s AC supply. In mode 6, the non-dim triggers
when DMX passes through 10%. In mode 8, the non-dim threshold
is 1%. All blocking diodes must be shunted (bypassed) in this mode.
