Installation\Setup
Power
Supply
The MC 6300 requires 12-15VDC to operate. This voltage can be either supplied by the
dimmer packs when using NSI dimmers through the Micro-Plex cable or by using an external
power supply connected to the power input jack when using non-NSI dimmers or the DMX
512 interface (power supply is provided with the DMX 512 option).
Micro-Plex runs of over 100 ft may require the use of the power supply. Micro-Plex and
the power supply may be used simultaneously.
Connect the power supply to the DC power connector on the back of the MC 6300 and
connect the other end to an 120V AC outlet. The console has no power switch.
Dimmer
Connection
The MC 6300 consoles come standard from the factory with two Micro-Plex (3 pin XLR
connectors) outputs. DMX 512 (5 pin XLR connector) dimmer control is optional .
Micro-Plex
Connecting the MC 6300 to NSI dimming systems is very simple. You need only connect
a single 3 conductor audio cable (standard microphone cable with 3-pin XLR connectors) or
equivalent shielded cable to the Micro-Plex output jack on the back of the console. The
other end of the cable is then connected to the first NSI dimmer pack. Another 3 conductor
cable is used to connect the first dimmer pack to the second dimmer pack. Additional NSI
dimmer packs may be connected in the same manner.
NOTE: Minimum 20 gauge high quality shielded cable is recommended in the run
between the console and the dimmers to prevent interference and dimmer flickering
caused by noise. 18 gauge cable is recommended in runs over 100ft.
DMX 512
DMX 512 is a digital signal that provides the highest speed, precision, and noise immunity.
Rules for connecting DMX 512 are more stringent:
•
Use cable that is specified as RS-485 or RS-422 compatible (1 or 2 twisted pair w/
shield) and use largest gauge available (22 - 18 gauge is good for long runs of 1000ft).
•
Daisy chain the cable only (no star or home runs) and terminate the end of the cable
with a 120 ohm resistor. (See dimmer manual for proper terminating practice).
Connect the cable from the dimmers to the marked connector on the rear of the console.
Configurati
on
The first time the MC 6300 is used, the configuration parameters may need to be set, otherwise
the unit may appear to be operating improperly. Please see the chapter, Configuration Guide,
in this manual for further details.
