4. Align the slots of each new firmware chip with the angled corners of the socket in the
same orientation as the old chip. Gently, but firmly, press the chip into place in the
socket.
5. Close the switcher (see “Opening and Closing the Switcher,” starting with step 9 on
page 65).
Installing a DVI Output Card
You can install an optional digital visual interface (DVI) output card in the ISS. With the card
installed, a additional DVI video output 1 on a standard DVI connector. The DVI output is
the video tied to output 1 and is in addition to the standard output 1 RGB video on BNC
connector and 15-pin HD connectors. Extron recommends that you send the unit to Extron
for service and updates.
Install an optional DVI output card in the ISM as follows:
ATTENTION: Changes to electronic components must be performed by authorized
service personnel only.
CAUTION: Electric shock hazard. To prevent electric shock, always unplug the ISS
from the AC power source before opening the enclosure.
1. Open the switcher (see Opening and Closing the Switcher on page 64).
ATTENTION: Do not touch any switches or other electronic components inside the
ISM. Doing so could damage the ISM. Electrostatic discharge (ESD) can damage
IC chips even though you cannot feel it. You must be electrically grounded before
proceeding with any electronic component replacement. A grounding wrist strap
is recommended.
2. Locate the DVI output card connector opening on the rear panel and the DVI output
card connector J14. When viewed from the front, connector J14 is in the far left corner
of the main circuit board (see figure 51).
