LCDD32 DEVICE DRIVER Configuration

LCDD32 Power: With power off, connect your control
power supply to the CC and CP terminals on J1. Observe
the correct polarity if DC power is used.
Device Power: With power off, connect your device
power supply negative to one of the OC terminals on J1.
Making sure that the correct polarity is observed.
Input: DMX input lines are connected to SH, D– and D+
on J1 (corresponding to XLR pins 1,2, & 3 respectively).
Output: Both momentary and maintained operation is
supported. For maintained operation, connect the
positive inputs on your DC devices to the positive output
on your device power supply. Connect the negative inputs
on your DC devices to the corresponding outputs on J3-
J6.
For momentary pulse latching relays, two signals are
required, ON and OFF. Up to 16 relays of this type can be
connected, using odd numbered outputs for the ON signal
and even numbered outputs for the OFF signal. See the
application notes for wiring diagrams.
Daisy Chain: If there are several DMX devices being
used, the DMX line can be daisy chained off of J1.
Termination: If this LCDD32 is the last DMX device on
the line, JP2 and JP3 should be installed.

The Programmable Device Driver can drive each output
with up to 500mA at 5-40VDC. If you exceed this limit, a
self-resetting fuse on each output will open.

OUTPUT DRIVER CAPACITY

MASTER SWITCH INPUTS

Master switch inputs function in a "highest level takes
precedence" (HTP) mode of operation with the DMX
signal. If the DMX level for a given device is above the set
threshold, the master switch will not turn that device off.
Similarly, lowering the DMX signal for a device will not
turn that device off if a master switch has previously
turned it on. This function allows the user to pre-set
devices to the ON state prior to lowering or shutting off
the DMX signal. In the absence of a DMX signal, the A
and B master switches will operate in a "last action takes
precedence" (LTP) mode, that is, either one will turn on or
off a device assigned to both switches.

The LCDD32 supports two different types of outputs: 16
momentary pulsed pairs or 32 maintained single outputs.
Many devices require a continuously maintained signal or
supply. Others require only a momentary or pulsed ON/
OFF signal. You can choose the desired output type by
setting the Options DIP switch. Setting switch 1 OFF
results in all devices responding with a maintained action
when addressed. Setting switch 1 ON results in all
outputs responding with a momentary action . The
duration of the momentary pulse is 100 msec. In
momentary mode, the LCDD32 operates as a 16 channel
device driver. Odd numbered outputs turn on as the DMX
level increases, and even numbers turn off as the DMX
level decreases.
