1Video Input cable — Attaches the interface to the computer or workstation. The type of connecter depends on the interface model:

RGB 109xi: 15-pin HD male

RGB 112xi: 13W3 male

2Buffered Local Monitor Output Connector — Attaches to the local monitor’s video signal cable. The type of connector depends on the interface model:

RGB 109xi: 15-pin HD female

RGB 112xi: 13W3 female

If you are not using a local monitor with the RGB 112xi, you must attach an MFTA (multi-frequency termination adapter) to simulate a monitor.

3ID Pin switches (RGB 109xi only) — Allows the user to set the correct ID bit termination:

ID PIN 4 & ID PIN 11

4	11	On — Set both pins to On (up) if you are using the

		not attached to a local monitor.

Off —Set both pins to Off (down) if you are attaching a local monitor to the interface.

4Horizontal Shift control — Controls the screen image horizontal centering. To adjust the horizontal shift, turn the knob in either direction and observe the left/right movement of the image on the screen. Stop when the image is centered.

If the DDSP™ DIP switch on the rear panel ( 3 ) is set to On, the horizontal shift control is disabled.

While the horizontal shift control is active, "H-SHIFT"appears in the scan rate indicator LCD ( 5 ) and for a further three seconds after the control is no longer active. When the control reaches its maximum or minimum point, "MAX" or "MIN" appears in the scan rate indicator LCD.

5Scan rate indicator LCD — Shows the scan rate for the selected input, in kilohertz (kHz), on the top line. The vertical scan frequency, in Hz, appears on the bottom line. In addition, if the horizontal shift control is activated, or the minimum or maximum limits are reached, the LCD displays the status.

1IEC AC power connector — Use this standard AC power connector with the supplied IEC power cable.

2Gain/peak switch — Compensates for cable capacitance if the signal cable between the interface and the display device is longer than approximately 125 feet (38m). Turn the switch to the position that provides the best image on the output display device.

100% — Increases the output signal level and adds 100% of the maximum peaking to the signal.

Unity — The output level is the same as that of the input, with no added peaking.

50% — Increases the output signal level and adds 50% of the maximum peaking to the signal.

If the signal cable between the interface and the display device is shorter than approximately 125 feet (38m), and the Gain/Peak switch is set to a setting other than Unity, the image may be overcompensated. If the edges of the image seem to exceed their boundaries, or if thin lines and sharp edges look thick and fuzzy, try changing the Gain/Peak settings.
