IN2200RS Operation Manual - V1.1 01/03/2001

POSITION

The Position (

¾,¿,½&¼) Arrows shift the video image in the designated direction. Operators can

press and release a button for small shifts or press and hold for large shifts. If the horizontal or
vertical positioning controls are disabled, the LCD display indicates the current status when the user
tries to adjust them.

SCREEN SHIFT

This function is enabled / disabled by pressing the GAIN (

¾ / ¿) Button during power-up.

When enabled, the image is slowly shifted in a clockwise motion to help prevent CRT or Plasma
display “burn-in.” A complete list of power-up options is provided on page 11.

Shift Range: The amount that the image is shifted can be set to “High” or “Low” during

the power-up sequence. The High Range is set by pressing and holding the
POSITION (

½) Button while turning on the power. The Low Range is set

similarly but holding the POSITION (

¼) Button while turning on the power.

Shift Speed:

When adjusting the size of the display it is important to allow for the shift
range. Therefore, there is a Fast Screen Shift Speed, which rapidly moves
through the entire shifting range (so users don't have to wait a long time for
the image to make a complete cycle), and a Slow Screen Shift Speed. The
Fast Screen Shift is set by holding the SHARP (

¾) Button during power-up,

and the Slow Shift Speed is set by holding the SHARP (

¿) Button.

FRONT PANEL DISABLE

The front panel is disabled / enabled with a dipswitch setting (#5 of Dipswitch Bank 2). When
the front panel is disabled, none of the front panel buttons operate. The LCD display will read
“Front Panel Disabled” whenever a front panel button is pressed. However, input selection can
still be made via the remote port or by setting the unit for Automatic Input Selection.

AUTOMATIC INPUT SELECTION

The IN2200RS can be set to automatically select the active input. An input is considered active if
it has a sync signal, or if pin 10 is grounded (usually done through the presence of an input cable,
regardless of whether or not a sync signal is present). If both inputs are active, Input 2 has priority.
If there is no active input signal (or pin 10 is not grounded) on Input 2, Input 1 is the default.
Note: When set to the Automatic Input Selection mode, the front panel and remote input selection
features are disabled. Dipswitch #6 on Bank 2 enables / disables the Automatic Input Select mode.

STATUS / MODE INFORMATION

Each time the unit is powered up, the LCD displays a sequence of screens to inform the user of how
the IN2200RS interface is configured. These screens show the following items: Automatic Input
Selection Enabled / Disabled, Front Panel Enabled / Disabled, Screen Shift Settings and the Output
Sync Format.

DIPSWITCH SETTINGS

Two dipswitch panels are easily accessed through windows on the bottom of the IN2200RS.
SWITCH 1 regulates the output sync format. SWITCH 2 determines the monitor emulation settings.

For most installations, the IN2200RS will be operated in the factory
default mode and will not require any changes to the dipswitch settings.
