Reference Information, cont’d

If you choose to check for proper operation before putting the cover back on, ensure that tools and hands are outside the switcher, and then connect the power cord to the unit and to an AC source. The switcher should power up normally. Unplug the AC power cord, and reinstall the switcher.

7.Attach the power cord to the switcher and to the AC power source. Ensure the switcher is working properly.

8.If the switcher was removed from a rack, remove its power cord, reattach the switcher to the rack, and reconnect the power cord.

9.

Reconnect the input and output cables.

Installing a firmware update

The IC that contains the firmware for the matrix switcher also contains the memory in which presets and audio levels are saved. When you replace the IC, these settings will be lost. You may want to record the presets and audio levels before you replace the IC.

To replace the firmware, do the following:

1.Follow the instructions in Opening the switcher on page B-2 for removing the top cover, including the instructions for removing the front panel.

2.Locate the RS-232/RS-422 ribbon cable that connects the front panel board to the rear panel RS-232/422 port (figure B-2). Note which receptacle on the front panel board that the cable plugs into, and remove the cable from its receptacle (see step 4 in Swapping the serial ports).

Do not touch the components inside the switcher without being electrically grounded. Electrostatic discharge (ESD) can damage ICs, even if you cannot feel, see, or hear it.

3.Unplug the power cable from the front panel board.

4.Place the front panel board, button side down, on a suitable workspace.

5.Locate IC U7 (see figure B-2).

6.Use the PLCC IC puller to remove the existing firmware IC. Squeeze the tool to align its hooks with the slots in opposite corners of socket U7.

Insert the hooks, squeeze gently, and pull the IC straight out of the socket. Set the IC aside.

7.Note the key (angled corner) of the new firmware IC and the

dot on the underside that indicates pin 1 (figure B-3). Orient the IC to match the key and pin 1 (indicated by the arrow), and carefully press the IC in place.
