Polarity is not important: the positive or negative wire may be connected to either of the outer poles.
5Bottom panel DIP switches — These four DIP switches, numbered 1 to 4 from left to right, control the sync on green, serration pulse, DDSP and composite sync output options.
1 — SOG (sync on green)
ON — When this switch is set to On, (sync on green), the interface will output sync on green.
OFF — When the SOG feature is set to Off, the interface will output either separate horizontal and vertical sync signals (on the H/HV and V connectors) or a composite sync signal (on the H/HV connector), depending on how DIP switch 4 is set.
2 — DDSP™ (Digital Display Sync Processing™)
ON — When this switch is set to On, the interface uses Digital Display Sync Processing instead of Advanced Digital Sync Processing™. Use this option if the image still doesn’t display properly after other options (changes to sync width, serration pulses and video termination) have been explored.
DDSP will disable horizontal shift control.
OFF — When this switch is set to Off, the interface uses ADSP™, Advanced Digital Sync Processing™.
3 — SERR (serration pulse)
Many display devices, including LCD and DLP projectors and plasma displays, must not have serration pulses in the vertical sync signal in order to display properly. Flagging or bending at the top of the video image is a sign that the serration pulses should be removed.
ON — When this switch is set to On, serration pulses will be output.
6Blue (B) output connector — BNC female connector for blue video output.
7Green (G) output connector — BNC female connector for green video output.
8Red (R) output connector — BNC female connector for red video output.
9Horizontal (H) or composite sync (HV) output connector (H/ HV) — BNC female connector for either separate horizontal sync or composite sync output.
10Vertical (V) sync output connector — BNC female connector for separate vertical sync output.
Top panel jumper switches
Video signals passing through long cable runs (over 125 feet) can decrease in strength, creating signal loss. The longer the cable, the higher the video level and the greater the peaking that will be needed to compensate for the loss.
The red, green and blue gain/peaking adjustment jumper switches are located on the top of the RGB 500 Series interfaces. You will need needlenosed pliers to reach and move the jumpers. Select the setting that yields the best image display.
Use the diagram on the product label, shown in the illustration, as a guide to setting the output gain/peaking for each color.
BLUE GREEN REDUnity
OFF — When this switch is set to Off, serration pulses will not be output.

4 — Composite sync
ON — When this switch is set to On, a composite sync signal (H and V combined) will be output on the connector labeled “H/HV”.
OFF — When this switch is set to Off, horizontal sync will be output on the connector labeled “H/HV”, and vertical sync will be output on the “V” connector.

•Use the left two pins to increase the output signal and add 50% of the maximum peaking to the signal.
•Use the middle two pins for unity output (0.7 volts,
no peaking).
