Instruction Manual

LCRC48GEP DMX RELAYCONTROLLER Configuration
INSTALLATION INSTRUCTIONS
1 -
Ensure that relay panel power is off (no indicator LEDs
glowing on the system motherboard). Remove the metal
cardframe cover.
2 -
Connect the DMX data line at the panel motherboard, with D-
to the black terminal and D+ to the red terminal. Attach the
shield drain wire to the SHIELD terminal.
3 -
If the DMX line is to be passed through to another panel,
attach the outgoing wires to the second set of data terminals.
4 -
If the relay panel is the last panel on the DMX wire run, it is
recommended that a 100 or 120 ohm 1/4W termination
resistor be installed between one pair of black and red data
line terminals.
5 -
Connect switch wiring to the A/B master switch input terminals
as required. The white terminal is switch common, the red is
switch "on", and black is switch "off". Connect the pilot lamp to
the yellow terminal adjacent to the first of the assigned relays.
6 -
Plug the controller card and one to four LCRD-12 driver cards
firmly into the cardframe.
7 -
Configure the controller card according to the following DIP
switch settings. Restore power.
8 -
Check that the power LED (between the DIP switch and the
three rotary switches) is glowing steadily. This indicates +5
volts present and correct microprocessor operation. A flashing
LED indicates a defective controller card.
9 -
Follow the program mode instructions to program the card for
optional DMX patch assignment and panel master switch
inputs.
10-
Apply the DMX control signal and observe that the receive
data LED (at left) is glowing. The LED will not glow if the
address set on the rotary switches exceeds either 512 or the
number of dimmer signals present on the data line, if the data
format does not conform to USITT-DMX512, or if the data
wires are reversed at the mother board.
11-
Verify relay operation with the DMX control system or the
card's test function, then use the checklist to ensure that
everything is set correctly before re-installing the cardframe
cover.
