Extron electronic manual DVS 304 Series Reference Information

WARNING: Do not touch any switches or other electronic components inside the

scaler. Doing so could damage the scaler. 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 middle rear portion of the main circuit board (looking from above with the front panel nearest to you)

5.Remove the plastic SDI cover from the rear SDI connector opening of the scaler 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.

7.Insert the card’s installation screw through the SDI card’s mounting hole and gently tighten it into the standoff.

8.Install the SDI connector’s hex nut and keep the SDI card from twisting as the nut is tightened.

9.Replace the top cover on the DVS 304 scaler, and fasten it with the screws that were removed in step 3.

10.Rack/furniture mount the scaler, if desired, and reconnect the AC power cord
