DMX-512 multiple control wiring
DMX-512 is the preferred type of control wiring because of the high
update rate and the resistance to interference. It is highly recommended
in locations subject to electrical noise. DMX-512 only requires 3 wires
transmit lighting levels to as many as 512 dimmer channels. DMX-512
should not be used simultaneously with Microplex. Most of the Leviton
lighting control consoles can use this interface.
Connect the three DMX-512 control wires to the appropriate terminals
provided on the power supply card. Duplicate terminals are provided
to carry the control connections to more dimmer packs if necessary. Be
sure to set the Channel Address on the dipswitches of the dimmer firing
cards as required. If a+ 15 VDC power source is required for the control
console, connect an additional wire to the + 15 VDC terminal on the
power supply board. This wire and the common wire must be at least
18 gauge. This power supply can deliver 750 MA maximum and can be
connected in parallel to other 2408 CD/CR packs.
If a +15 VDC power source is required for the control console, connect
an additional wire to the + 15 VDC terminal on the power supply board.
This wire and the common wire must be at least 18 gauge. This power
supply can deliver 750 MA maximum and can be connected in parallel to
other 2408 CD/CR packs.
Microplex multiplex control wiring
Microplex is the control protocol used on all Leviton lighting console. This
system uses a shielded wire to transmit up to 128 channels of dimmer
control. Microplex should not be used simultaneously with DMX-512. For
short distances (50 feet) a standard microphone cable is used to carry
both the control signal and the DC power source for Leviton control
consoles. Longer distances may be accommodated with 18 gauge or
better cable to reduce voltage losses of the power supply.
Connect the Microplex control wires to the appropriate terminals on
the power supply card. If an XLR type connector is used to connect the
control console, connect pin 1 to common, pin 2 to + 15 VDC, and pin
3 to MICROPLEX. A duplicate set of connections is provided to carry the
control signal to more dimmer packs. Be sure to set the Channel Address
dip switch as required.
SWITCH SETTINGS
When using any of the multiplex control systems the dip switches on
the 2408 CD/CR must be set to assign the desired dimmer channels.
The switches control the dimmer channels in groups of four. The dip
switch on the left dimmer firing card controls circuit channels 1-4
while the dip switch on the right card controls circuit channels 5-8 of
the pack. Both switches may be set to the same settings if only four
control channels are desired. See the following chart for settings.
