It is not important which wire
(positive or negative) connects
to which outer pole of the 3-pole
captive screw power connector.
• The center pole is not used.
• AC
or DC power may be used.

Audio output captive screw connector
— This 3.5 mm, 5-pole
right angle captive screw (Phoenix) connector
will be used for balanced/unbalanced audio
output. Attach the five wires for audio output
of ground, left and right channels to the
connector; follow the wiring guide on the
bottom panel label or the one shown below.
Insert the wires into the appropriate openings. Tighten the
screws on top to fasten the wires.
Connect the sleeve to ground (GND). Connecting
the sleeve to a negative (-) terminal will damage the
audio output circuits.

Sync polarity jumper switch
— This jumper switch adjusts the
output sync polarity. Horizontal and vertical
sync output can either follow input sync
polarity, or be forced to negative. You will
need needlenosed pliers to reach and move
the jumper. See the diagram below.
• If the jumper is placed on the two left pins, output sync
polarity follows input sync polarity.
• If the jumper is placed on the two rightmost pins, output H
and V sync polarities will be forced to negative.

Vertical sync width jumper switch
— This jumper switch
adjusts the vertical sync pulse width. For
some digital display devices, if no picture
displays, the picture cuts in and out, or the
picture is scrambled, try adjusting the vertical
sync pulse width or switching from ADSP to
DDSP.
You will need needlenosed pliers to reach and move the jumper.
See the diagram below.
• If the jumper is placed on the two leftmost pins, the output
vertical sync pulse will be narrow.
• If the jumper is placed on the two right pins, the output
vertical sync pulse will be wide.

Captive screw power connector —
Use this 3-pole, 3.5 mm
captive screw power connector with a 12 to 24VDC or
12 to 24VAC, 0.35A, external, autoswitchable power supply,
such as Extron’s #70-055-01.
The center pole contains no conductor. Connect
conductors to the outer two poles only.
