OUTPUT SIGNAL FORMAT SELECTION

Automatic Sense Mode - In the factory default configuration, the IN2022HR automatically
senses the number of cables connected to the output BNC connectors and selects the
appropriate output signal format. LED indicators located next to the V/Sync, H/Comp Sync
and Green output BNCs (on the back of the interface) provide clear visual confirmation of
the current output sync format. In order for output format auto sense circuit to operate,
dipswitch 5 must be set to 1.

Manual Mode - Some applications will require the interface to operate in a specific output
format, thus requiring users to override the automatic sense mode. To set the output sync
format manually, users must first disable the auto sense circuit by setting dipswitch #5 to 0,
and then setting select dipswitches according to the table below (to set the desired output
format).

Keep in mind that PCs and MACs operate in several video modes
encompassing a wide range of resolutions and scan rates. The data
projector or monitor must be compatible with the horizontal scan and
vertical refresh rate of the computer’s video signal. Please check the
documentation for both the computer graphics card and the data display
device to ensure compatibility.

DIPSWITCH BANK 2: MONITOR EMULATION

The IN2022HR includes a bank of 10 dipswitches on the bottom of the interface for monitor
emulation. Setting the dipswitches to the appropriate positions allows the unit to emulate the
appropriate sense signals, thus setting the video card to the desired frequency, refresh rate
and resolution, even without a local monitor. When configured properly, the interface can
emulate virtually any type of monitor.
