Installing A Software Update

To install a software update, IC U9 or U6 (or both) on the Main Control printed circuit card is replaced. If the system consists of multiple BMEs, the software IC(s) in each BME’s Main Control PCB may need to be updated. Use the following procedure to replace the Matrix 6400 Audio Main Control PCB IC(s).

1.Power the system OFF and unplug the AC power cord.

2.Remove the Access Panel. See Page 5-3.

3.Use the PLCC IC puller (Figure 5-3.A) to remove the existing Software IC. Squeeze the tool to align the hooks with the slots provided in opposite corners of IC socket U9 or U6. Insert the hooks, squeeze gently and pull the IC straight out of the socket. Set the IC aside.

4.Note the key (angled corner) of the new Software IC. Orient this to match the key of the socket and carefully press it in place.

5.Reinstall the Access Panel.

6.Plug in the AC power cord, power the system ON.

7.Verify that the switcher is working properly.
