Multiplex control input connections are made through the five pin
male XLR on the back of the unit. Analog control input connections
are made through the DB-15 male connector inside the unit. For
analog use, the Dimmermaster requires 8 control inputs, referenced
to a signal common. This common is isolated from the neutral and
chassis. Signal voltage is 0 to +10 volts pure DC. Maximum output
is obtained at +10 volts.

F// Indicators
The status indicator LED is used to check the Dimmermaster for
proper control and power connections. It shines green when it is
receiving power and is being addressed properly by a multiplex
controller, and both red and green (amber) when it is receiving
power but not a proper multiplex signal or is incorrectly set up.
It also shines both red and green when it is set up for an analog
signal. No light at all means that it is not receiving power.
It is also very important that the input voltages be checked with a
meter to insure that they are correct. A mistake can place
208 to 240 volts across a 120 volt lamp. The breakers will protect
the unit but may not save your lamps. A double check of voltages
before applying power can guard against such disaster.
C// Grounding
The term GROUNDING refers to a separate wire with green insulation
which is connected from the equipment case to earth ground
(often through a properly grounded conduit system). This is not the
same as the neutral or common and must not be confused with them.
The neutral is a separate, load-carrying circuit conductor. The ground
conductor should not normally carry current. When the
Dimmermaster is connected to its power source by conduit, the ground
connection can be made via the conduit itself. If flexible conduit is
used, a separate bonding conductor will usually be required.
Always check your local codes for hook-up before operating this
equipment. It is recommended that power connections to the
Dimmermaster be made by a qualified electrician.
D// Load Connections
The Dimmermaster 824 will dim any load from 1 watt through
2400 watts. The load may be incandescent, inductive, or resistive.
This includes conventional incandescent, quartz incandescent,
rain-lights, pin beams, and similar lamp loads. The output connector
can be U-ground, stage pin, or terminal block.
If your unit has receptacles installed, merely plug the load into the
outlet which corresponds to the circuit you desire to use.
For terminal-block-only units, there is one lug for each output and
one for all neutrals. There must be a separate neutral returning
from each load circuit. DO NOT COMMON NEUTRALS BETWEEN
DIMMER AND LOAD. Lugs are numbered according to their circuits.
E// Control Connections
The DM824D can take any of three control protocols:
USITT AMX-192, DMX-512, or 0 to +10VDC analog.
The multiplex control protocol is factory set as per the customer's
requirements, but it can be changed through jumpers on the circuit
board. See Control Input Connections Chart for jumper locations.
