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 relay (or pack) 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 be connected between the remaining jack and another relay pack. Many relay 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 relay channels of the DDS 3600R may be operated by an analog 0 - 10 VDC control voltage. This type of control
will provide 0% intensity at less then 1 volt and 100% intensity at greater than 2 volts (to a maximum of 10 volts). Any or all of
the DDS 3600R relay channels may be operated in this manner simultaneously with any multiplex control input. Each relay 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 relay 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.
