To change the Host baud rate from the factory setting of 9600 baud

To upgrade the Main Controller Board Software chip

1. Unplug the AC power cord.

2. If rack-mounted, remove the System 8/10 P

from the mounting rack.

3. Remove all input and output cables.

4. Place the System 8/10 P

5. Go to the procedure for which you have opened the cover (see following pages).

Changing SW1 Switch Settings

_____ The SW1 DIP switches, as illustrated below, should ONLY be changed when

resetting switches 3 and 4! Switches 1, 2, and 5 must NEVER be reset! Failure
to heed this warning could seriously affect the operation of the switcher.

Locate SW1 on the Main Controller board (see diagram on next page).

Switch 3:

When set “ON” - if the connected projector is in ‘Display Mute’ mode,

the front panel’s Input Select button will not be illuminated.

When set “OFF” - if the connected projector is in ‘Display Mute’ mode,

the front panel’s Input Select button will be illuminated.
