Serial Digital Interface (SDI Card Installation
The optional SDI card may be installed in the scaler if it does not already have an
input for a serial digital interface signal. We recommend that you send the unit in
to Extron for service and updates.
N Changes to electronic components must be performed by authorized service
personnel only.
Follow these steps to install an SDI card in the DVS 304.
1. Disconnect the AC power cord from the DVS 304 to remove power from the
unit.
W To prevent electric shock, always unplug the DVS 304 scaler from the AC
power source before opening the enclosure.
2. Remove the scaler from the rack or furniture.
3. Remove the cover of the scaler (the top half of the enclosure) by removing the
screws, then slide the cover back to clear the connectors and lift it straight up
(figure B-1).
