Serial Digital Interface (SDI) Output Card Installation
The optional SDI output card may be installed in the VSC if it does not already
have an output for a serial digital interface signal. We recommend that you send
the unit in to Extron for service and updates.
Changes to electronic components must be performed by authorized
service personnel only.
Follow these steps to install an SDI card in the scan converter.
1. Disconnect the AC power cord from the VSC to remove power from the unit.
Then disconnect the input/outut cables.
To prevent electric shock, always unplug the VSC from the AC power
source before opening the enclosure.
2. Remove the VSC from the rack or furniture.
3. Remove the cover of the scan converter (the top half of the enclosure) by
removing the screws, then lifting the cover straight up. See the top cover
removal diagram in the Firmware Upgrade Chip Installation section.
Do not touch any switches or other electronic components inside the scan
converter. Doing so could damage the scan converter. 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.
4. Locate the SDI card standoff located near the left rear portion of the main
circuit board (looking from above with the front panel nearest to you).
5. Remove the adhesive SDI cover from the rear SDI connector opening of the
scan converter and position the SDI card at an angle with the SDI connector
protruding from the rear SDI connector opening.
6. The SDI card has a 20-pin socket on the underside which should align with
the 20 pins on the main circuit board. Be sure to align the pins properly, in
order to prevent bending the pins, before pressing the SDI card firmly in
place against the standoff. The mounting hole on the SDI card should now
be directly over the standoff.
