1 Video input cable — Attaches the interface to the

computer or workstation. The type of connecter

depends on the interface model:

While the horizontal shift control is active, H-SHIFTappears in the scan rate indicator LCD ( 5 ) until three seconds after the control is no longer active.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, the LCD indicates when the minimum or maximum limit is reached.

3ID pin switches (RGB 109xi only) — Provides proper ID bit termination. See page 2-9 for information on setting switches.

ID PIN 4 & ID PIN 11

ON — Set both pins to On if you are using the RGB 109xi interface with a laptop computer that is not attached to a local monitor.

OFF — Set both pins to Off 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 and observe the left/right movement of the image on the screen. Stop when the image is centered.

If the DDSP™ DIP switch is set to On, the horizontal shift control is disabled.

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. 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
