MICROPLEX MULTIPLEX CONTROL WIRING.
Microplex is the control protocol used on most NSI lighting consoles. This system uses a single three conductor
cable to transmit up to 128 channels of dimmer control. For short distances (50 feet or less) a standard microphone
cable may be used to carry both the control signal and the DC power source for NSI 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 cable to either of the three pin XLR jacks. Since both jacks are wired in parallel,
another control cable may connected between the remaining jack and another dimmer pack. Many dimmer packs
may be "daisy chained" together in this manner.
Be sure to set the Channel Address dip switch as required (see DIP SWITCH SETTINGS).
ANALOG 0 - 10 VDC CONTROL WIRING.
Each of the four dimmer channels of the may be operated by an analog 0 - 10 VDC control voltage. This type
of control will provide 0% intensity at 0 volts and 100% intensity at 10 volts. Any or all of the DDS 5300 / 5600
dimmer channels may be operated in this manner simultaneously with the any multiplex control input. Each dimmer
will respond to the greater of any control inputs.
The analog control input uses a standard 5 pin DIN plug which is available from most electronics supply houses.
Connect each of the positive channel control wires to the desired dimmer channel input pins (see diagram) of the
plug. Connect the common (ground) control wire to the pin indicated on the diagram. Consult the documentation
of the analog control console or device you are using for the proper connections. The control input impedance is
4.7K ohms.
