There are different output card options available, for the four expansion slots
at the rear of the ISM 824. Figure 2-2 shows the following four:
ê
ISM VS Video scaler card — Connect RGB video displays to this set of
5 female BNC connectors to output scaled or unprocessed signals
(RGBHV, RGBS, RGsB, or HD component (YUV) video).
ë
ISM 2WB Dual wideband card — Connect RGB video, component/
HDTV video, S-Video, or composite video displays, as applicable, or other
devices to these 15-pin HD connectors for each output.
N
For the installation configuration shown in figure 2-2, the top 15-HD pin
connector is output 5, and the lower 15-pin HD connector is output 6.
í
ISM SC Scan Converter card — Connect video displays to this set of 3
female BNC connectors to simultaneously output converted (downscaled)
signals (RGsB, component video, S-video, or composite video) and a
composite video on a single BNC connector. Also an external blackburst
signal may be connected to the input (Genlock In) BNC connector for
genlocking the video signal in broadcast or other sync critical applications.
ì
ISM RGB Universal Scaler card — Connect RGB video displays to this set
of 5 female BNC connectors to output scaled signals (RGBHV, RGBS,
RGsB, or HD component (YUV) video).
The fifth optional output card type is:
ISM 1WB Single wideband card — Connect an RGB video, component/
HDTV video, S-Video, or composite video display to this set of 5 female
BNC connectors to output unprocessed video signals.
Audio output connections
Audio output connectors — Connect audio devices, such as an audio
amplifier or powered speakers to the 3.5 mm, 5-pole captive screw connectors
on the card. The connectors output the selected unamplified line level audio.
See figure 2-10 to properly wire an output connector.
