Firmware Upgrade Installation In some cases the QSD 204’s firmware may require replacement with an updated version. There are three user-replaceable firmware chips: U41 — the main microcontroller, U38, and U17. The numbers are printed on the circuit board. We recommend that you send the unit to Extron for service and updates. Changes to firmware must be performed by authorized service personnel only. Some QSD 204 firmware updates must be performed at the Extron factory.
Appendix, cont’d U17 U38 U41 Locating the three firmware IC chips 5. After you are electrically grounded, the U17 or U38 IC chip may be removed by grasping it firmly with your fingers and pulling it out, then continuing to step 8. Removal of the U41 IC chip requires a PLCC IC puller tool. To remove the U41 chip, align the hooks of a PLCC IC puller tool with the slots located in opposite ends of the U41 firmware chip. A-6 6.
Serial Digital Interface (SDI) Card Installation The optional SDI card may be installed in the decoder 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. Changes to electronic components must be performed by authorized service personnel only. Follow these steps to install an SDI card in the QSD 204. 1. Disconnect the AC power cord from the QSD 204 to remove power from the unit.
Appendix, cont’d 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. 20-pin socket on back of SDI card 20-pin connector on main board A-8 7.
