1Auto power LED — If active sync pulses are present, power and this LED turn on. If not, power and this LED turn off.

2H. 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.

3Input — This 9-pin D-sub male connector is for RGB input.

4High Z/75 Ohm switch — For proper video termination, set this switch to 75 Ohms if no local monitor will be connected.

5PC 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.

8Pin assignment label for the audio output captive screw connector (item 9) — Audio output wiring is discussed in the cabling section of this chapter.

9Audio 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.

10J13 jumper — Pin 1 = +5V, pin 2 = -5V, pin 3 = ground.

11SW1 DIP switches — 1. ON = Removes serration pulses. 2. ON = Enables Digital Display Sync Processing (DDSP).

12J10 blue gain/peaking jumper — Settings are shown on the label located below the circuit board.

13J9 green gain/peaking jumper

14J8 red gain/peaking jumper

15Circuit board — Only key components are shown here.

16Twisted-pair wires — Splice these wires to a 12 to 24VAC or VDC power source.

17Composite video pass-through RCA connector—If unused, this connector can be replaced with a 0.31” diam. plug.

18S-video pass-through 4-pin mini DIN connector — This connector can be replaced with a 0.50” diam. plug.

19BNC output connectors — These 6 connectors are for video and sync output. Connect the coax cables’ BNC connectors
