down the unit when the input cable is removed. Auto monitor emulation emulates a VGA / MAC monitor
when no local monitor is present.
In addition the IN2112R features:
•
Analog Interface - the unit will operate with Analog Video with TTL level sync signals. The signal
can be separate H & V or composite sync.
•
Sync Polarity Preservation Switch - enables the sync polarity to be preserved, or to be set for negative
polarity (for RGBHV signals in and out).
•
Serration Pulse Removal Switch - (for RGBS or RGsB output) enables the user to remove serration
pulses from the sync output.
Compatibility
INPUT
The IN2112R will accept high-resolution video signals from virtually any computer that outputs an analog
video signal (VGA, SVGA, XGA, MAC, SUN, SGI and other high-resolution computers) at virtually any
refresh rate. Input signal compatibility parameters are:
Video
Signal: Analog RGB Video
Signal Format: RGBHV, RGBS, RGsB*
Horizontal Frequency Range: 30 KHz to 130 KHz
Vertical Refresh Rates: 30 Hz to 120 Hz
* The IN2112R will operate with RGsB input signals. However, the unit will not strip
sync off of the green. RGsB input signals are always output as RGsB (they cannot be
output as RGBS or RGBHV). Also, the horizontal position control will not operate
when used with RGsB input signals.
OUTPUT
The output signal of the IN2112R is analog RGB video with TTL sync on 3, 4 or 5 female BNC connectors.
The output format can be set to RGBHV, RGBS or RGsB using dipswitches. This output signal is
compatible with high-resolution data grade monitors and data / graphics projectors.
