When enabled allows analog dimmer
outputs to be brought to full one at a time
as selected by the rotary address switches.
OUTPUT VOLTAGE ADJUSTMENT (all models)
Remove the six screws from the top cover of the decoder unit,place the unit in
test mode (S1-2 on) and set the address switches to 000 or 001. Ensure that the
decoder is connected to dimmer no. 1 and connect a DC voltmeter between
COM and output terminal no. 1 on the circuit board. Adjust P1 to achieve the
desired control voltage.
OUTPUT CONNECTOR ASSIGNMENT (all models)
If your decoder uses 25-pin D-type output connectors, you must install JP1 on 24
channel units or JP3 on 48 channel units. This will reassign the output control
signals to conform to the analog pin assignment detail on page 3.

(24 channel models)
CAUTION - Disconnect power from the unit before making any changes!
For 10V systems, JP1 and JP2 are installed; remove them for 15V systems. For
positive outputs, jumper pins 2 and 3 of JP4, 5 and 6, and install diode packs DP1-
6 with the notch facing down. For negative outputs, jumper pins 1 and 2 of JP4, 5
and 6, and install the diode packs with the notch facing up. Before powering up,
check to make sure that all jumpers are installed correctly. Damage will result if
the unit is powered up with any jumpers in the wrong position.
For 10V systems, JP2 is installed and
JP3,
JP4 are removed. For 15V
systems, JP2 is removed and JP3, JP4
are installed.
This switch is active only on 48 channel
models.
A 100-ohm resistor is connected across the
DMX data pair. Unit should be terminated if
it is the last receiving device on the DMX
line.
