8 Pin assignment label for the audio output captive screw
connector (item 9) — Audio output wiring is discussed in
the cabling section of this chapter.
9 Audio output captive screw connector — Use this
connector for the balanced output from both audio channels
(1 and 2). See the wiring diagram label (item 8) and the
cabling section in this manual for wiring instructions.
10 J13 jumper — Pin 1 = +5V, pin 2 = -5V, pin 3 = ground.
11 SW1 DIP switches — 1. ON = Removes serration pulses.
2. ON = Enables Digital Display Sync Processing (DDSP).
12 J10 blue gain/peaking jumper — Settings are shown on
the label located below the circuit board.
13 J9 green gain/peaking jumper
14 J8 red gain/peaking jumper
15 Circuit board — Only key components are shown here.
16 Twisted-pair wires — Splice these wires to a 12 to 24VAC or
VDC power source.
17 Composite video pass-through RCA connector —If unused,
this connector can be replaced with a 0.31” diam. plug.
18 S-video pass-through 4-pin mini DIN connector — This
connector can be replaced with a 0.50” diam. plug.
19 BNC output connectors — These 6 connectors are for video
and sync output. Connect the coax cables’ BNC connectors
as shown here for red, green and blue
video output, and either separate
horizontal and vertical sync or
composite sync.

1 Auto power LED — If active sync pulses are present, power
and this LED turn on. If not, power and this LED turn off.
2 H. Shift (horizontal shift) control — This controls the
horizontal centering. If output is SOG or if DIP SW1-2
(DDSP) is set to On, the horizontal shift control is disabled.
3 Input — This 9-pin D-sub male connector is for RGB input.
4 High Z/75 Ohm switch — For proper video termination, set
this switch to 75 Ohms if no local monitor will be
connected.
5 PC type 3.5 mm stereo audio input connector — This
connector is for unbalanced input to audio channel 2. Wire
the input plug as shown here.
