While the horizontal shift control is active, H-SHIFT
appears 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three seconds after the control is no longer active.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.
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, the LCD indicates when the
minimum or maximum limit is reached.

1
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. 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

ID bit termination. See page 2-9 for information on
setting switches.

ON — Set both pins to On if you are using the
RGB 109
xi
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.
4
Horizontal 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.
