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 to gain access to the interior of your switcher, including the instructions to remove 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-7). 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 (figure B-7).

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-8). Orient the IC to match the key and pin 1 (indicated by arrow) on the socket, and carefully press the IC in place.

8.Reinstall the power cable that was removed in step 3.

9. Reinstall the RS-232/RS-422 cable removed in step 2. Ensure the RS-232/ RS-422 ribbon cable is plugged back into the proper receptacle for the communications format desired (RS-232 or RS-422).

10.Reinstall the switcher’s front panel and cover. See Closing the switcher on page B-3.

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 perform step 11. After recognizing the new IC, the switcher should power up normally. Unplug the AC power cord, and reinstall the switcher.

11.Reinitialize the switcher to recognize the new IC as follows:
