The Extron ISM SC is a scan converter output board for the ISM 824 with four 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.
For full operating details of the ISM refer to the
ISM 824 User’s Manual, online at www.extron.com.
To install an output board in the ISM 824 base unit,
1. Turn off the ISM 824, and remove the power cord.
Repeat for all connected devices.
2. At the rear, select an open slot, or take out the blank
plate from the desired output port by removing the
two retaining screws (top and bottom), and lifting
the blank away.
N Re-use the screws to secure the new output
3. Remove the board from its outer box and anti-ESD
4. With the board upright, align the front (non-connector end) of the board with the top and
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.
bag, holding the board by the rear frame.
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.
5. If applicable, repeat steps 2 through 4 for any other output boards.
6. Power on the ISM 824. The new output board(s) is autodetected, and
takes 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 for a new ISM SC board installed in slot #2,
with 14 seconds left.
7. Following the image at right, connect output device cables
to the BNC connectors to output RGsB, component, S-video or
composite video signals. The output can be configured from the
front panel or by SIS™ commands. The composite video output
(the bottom BNC connector) is always active.
8. 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.
