DMX CONNECTIONS
The FXLD548C4O has permanent DMX in and DMX
out cables. Two DMX adapter cables are also supplied
to enable the use of 3 pin XLR connections.
A system using DMX control should be connected as a
chain of devices. In other words the control signal
cable should proceed from the controller to the first
receiving device and then to others in a continuous
"daisy chain" fashion. The control cable should NOT
be split into a multiple run star arrangement with a
cable running from the controller directly to each
receiving device.
DMX CONNECTOR PIN ASSIGNMENTS
There are normally two different connectors used for
DMX control. They are both XLR type connectors.
Some units use 3 pin connectors. Others use 5 pin
connectors. The FXLD548C4O
receives a DMX signal
on the 3 pin MALE connector on one side of the unit.
The 3 pin FEMALE connector is used to connect the
next DMX device on the control chain. If your console
uses a 5 pin connector you can make up an adapter
cable to convert. The table below shows the pin
assignments for BOTH the 3 pin and 5 pin connectors.
The permantly attached DMX in and DMX out cables
are not XLR connectors but follow the same pin
assignments as 3 pin XLRs.
DMX TERMINATION
A DMX chain should be terminated at the last
receiving device on the chain. This is done by
installing a commonly available 1/4 Watt, 120 Ohm
resistor across the DATA - and DATA + wires at the
last device. If you have only a few fixtures very close
together and a very short run to the controller then you
may be able to operate without the terminator.
OPERATION
A control panel on one side of the unit is used to set the
operating options. It consists of an LED display and
four buttons
(MENU, UP, DOWN, and ENTER)
Push
MENU
to access the operating options. Then use
UP
and
DOWN
to scroll through the available choices.
When you reach the option you want to set or change -

.
Now you can view the current setting
for the option and/or change it. Push
ENTER

diagram for additional details.
There are 12 operating options: DMX address, White
Level, Blue Level, Green Level, Red Level, Flash
Sequence, Fade Sequence, Auto Sequence, Run
Program, Program Speed, DMX Mode, and Slave
Mode.
When the unit is powered on it begins operation in the
state it was in when the power was last turned off.
