Optional output card connections

Video output connections

I 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:

ÊISM 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).

ËISM 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.

NFor 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.

ÍISM 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.

ÌISM 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.
