Disabled (Normal Operation)

Enabled

When enabled allows analog dimmer outputs to be brought to full one at

a time as selected by the rotary address switches.

DMX Line Terminated ON

This switch connects a 100-ohm resistor across the DMX data pair. The

unit should be terminated if it is the last receiving device on the DMX

line, otherwise leave this switch OFF.

ADDRESS SELECTION

Three rotary switches select the offset start address for the unit in most

configurations. In test mode, the switches set dimmers to full one at a

time. The switches are set as (S4) hundreds, (S3) tens and (S2) ones.

OUTPUT CONFIGURATION

Place the unit in test mode (S1-2 on) and set the address switches to

000 or 001. Ensure that the decoder is connected to dimmer no. 1 and

JP1 & JP2 are in the correct positions. Connect a DC voltmeter between

COM and output terminal no. 1 on the circuit board. Adjust P1 to achieve

the desired full on control voltage.

CAUTION:

Disconnect power from the unit before making any

changes.

Before powering up, check to make sure all jumpers are in-

stalled correctly. Damage will result if the unit is powered

up with any of the jumpers in the wrong position.

For 4-12V output, install JP1 and JP2.

For 12-15V output, remove JP1 and JP2.

For positive outputs (factory default), jumper pins 2 and 3 of JP4, 5 and 6 and

install diode packs DP1-6 with the notch facing down (left).

For negative outputs, jumper pins 1 and 2 of JP4, 5 and 6, and install the diode

packs with the notch facing up (right as referenced by the above diagram) if you

have MAD1108s or down (left) if you have diodes in carriers.

If J2/J3 are used with DB25 output connectors, install JP3 to reassign the analog

output signals as shown in the Connector Legend Chart, otherwise DO NOT install

JP3.

RUN

Glowing steadily indicates power supply and processor

OK; off indicates no power, and flashing indicates de-

fective processor hardware.

RxD

Glowing steadily indicates data signal received; off in-

dicates no signal present. Note that an address selec-

tion out of the range of the data signal will extinguish

the LED.

Two LEDs are used to indicate power supply and processor run

status and data receive detection.
