Removing the System 8/10 P

Cover
There is rarely a need for the user to remove the System 8/10 P LUS cover.
Three possible reasons would be:
• To change the Main Controller Board SW1 switch settings (switches 3 & 4
only)
• 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
LUS
from the mounting rack.
3. Remove all input and output cables.
4. Place the System 8/10 P LUS on a clean work space and remove the six (6)
screws shown in the picture.
5. Go to the procedure for which you have opened the cover (see following pages).
_____ Do NOT touch any switches or electronic components, other than those
specified. This could seriously affect the operation of the system.
6. When finished working inside the System 8/10 P LUS , use this procedure in
reverse to replace the cover.

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).
