The Extron
®
ISM VS is a video
scaler board for the ISM 824,
and outputs scaled low
resolution (composite, S-video,
and YUVi) signals and passes through RGB and HD component signals. It has
5 female BNC connectors and a local audio output. The board mounts in one of the
four vertical expansion slots (numbered 1 to 4) at the rear of the ISM 824.
Refer to the ISM 824 User Guide, available at www.extron.com.
To install an ISM VS output board in the ISM 824 base unit:
1. Turn off the ISM 824. Remove the power cord. Repeat for all connected devices.
2. Select an open slot at the rear, or take out a blank plate by removing the two
retaining screws (top and bottom), and lifting the plate away.
NOTE: Retain and re-use the screws to secure the new output board in place.
Retain the blank plates. If a board is already installed in the desired
slot, remove the screws and carefully pull out the board.
3. Holding the new board by the frame,
align the front (non-connector end) of the
board with the top and bottom plastic
guides in the ISM 824. Slide the board in
carefully, keeping within the guides. Push
it into place firmly, and secure it with the
retained screws.
4. If required, repeat steps 2 through 4
for any other output boards.
5. Power on the ISM 824. Any new output
boards are autodetected, and take
approximately 30 seconds to initialize. The 16 character LCD
display indicates the new board type, slot used, and counts
down the initialization
time. See inset for example display of a new ISM VS
board installed in slot #1, with 11 seconds left.
6. Following the image at right, connect output device
cables to the BNC connectors to output RGBHV, RGsB
video, RGsB, or HD component video signals. The output
can be configured from the front panel (see page 2) or
by SIS
™
commands (see pages 3 and 4).
7. Insert a 5-pole captive screw connector into the local
audio output connector for balanced or unbalanced
stereo audio output. Wire the connector as shown below.
