Auto power LED — If this LED is on, power and video sync pulses are present. If no sync is present, power and this LED turn off.

H. Shift (horizontal shift) control — This controls horizontal centering. If output is SOG or if DIP SW1-2 (DDSP) is set to On, the horizontal shift control is disabled.

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

Audio input 3.5 mm stereo PC-type connector for unbalanced input — Wire the PC audio input plug as shown here.

Tip (+) Sleeve (GND)

Ring (R, -)

7BNC output connectors — These 6 connectors are for video and sync output. Connect the coaxial cables’ BNC connectors as shown here for red, green and blue

H	G	video output, and either separate

8J13 jumper — Pin 1 = +5V, pin 2 = -5V, pin 3 = ground.

9Audio output 3.5 mm, 5-pole captive screw connector

— The label below this connector provides a wiring diagram for balanced audio output.

10SW1 DIP switches —

1.ON = Remove serration pulses.

2.ON = Enable Digital Display Sync Processing (DDSP).
