1
  Video 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
2
  Buffered 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.
3
  ID Pin switches (RGB 109xi only) — Allows the user to set the 
correct ID bit termination: 
ID PIN 4 & ID PIN 11 
On — Set both pins to On (up) 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 (down) if you are attaching 
a local monitor to the interface.
4
  Horizontal 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after the control is no longer active.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.
5
  Scan 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.

  IEC AC power connector — Use this standard AC power 
connector with the supplied IEC power cable.
2
  Gain/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.
