IN2022 OPERATION MANUAL - REV 1.1 12/11/99
INPUT COMPATIBILITY
The IN2022 will accept high resolution video signals from VGA video cards with a 15-pin HD
connector or MAC II-type video cards with a 15-pin D video connector. Input signal
compatibility parameters are listed below.
Video Signal:
Analog RGB Video
Connector:
VGA: 15-Pin HD female video port on computer
MAC: 15-Pin D female video port on computer
Signal format:
RGsB, RGBS, RGBHV, RGBSHV, RGsBS, RGsBSHV
Horizontal Frequency Range:
20 KHz to 130 KHz
Vertical Refresh Rates:
30 Hz to 120 Hz
OUTPUT COMPATIBILITY
The IN2022 outputs an analog RGsB, RGBS, RGBHV or Composite Monochrome signal on
female BNC connectors. This output signal is compatible with high resolution data grade
monitors and data / graphics projectors. PCs and MACs operate in several video modes
encompassing a wide range of resolutions and scan rates, and many of the video signals from the
newest models may have very high scan rates (60 KHz or more) and very high resolution (1280 x
1024 is common). The data projector or monitor must be compatible with the horizontal scan
rate 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.
Installation steps are listed below and outlined in Diagram 1 on page 5.
#1 Turn the computer and computer monitor off.
Disconnect the computer monitor from the computer’s video port.
#2 Check the Monitor Emulation dip switch settings on the bottom side of the IN2022.
Using Local Monitor - If you are using a local monitor (most installations) make sure
that all dip switches in the box labeled
MONITOR EMULATION
are set to “0”.
No Local Monitor - If you are not using a local monitor, gently set the dip switches
using the Inline tool provided according to the chart found on page 7.
The IN2022 is not a scan converter or encoder. This unit does not change the horizontal
scan rate, resolution, or convert the signal to NTSC composite video. The display device
connected to the IN2022 output must be compatible with the horizontal scan rate, vertical
refresh rate and resolution of the workstation video signal.

NSTALLATION
Check the Monitor Emulation chart and dip switch settings carefully. An improper
setting of the emulation dip switches may lead to improper operation and could even
result in severe damage to the computer video port or the monitor. If you are in doubt as
to which monitor emulation to choose, set all the Monitor Emulation dip switches to “0”
and connect a local monitor.
