Extron Electronics DVS 304 Series User Guide - Manual (Page 89)

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.
NOTE: 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.
WARNING: 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).
