2.3.1 Setting DIP Switches on the CPU/System Controller Board
Before you install the CPU/System Controller board, you must
determine the settings for three banks of DIP switches. Refer to Figure
2-6 for the location of the DIP switch banks. Refer to Tables 2-1, 2-2,
and 2-3 for an explanation of the DIP switch positions.
Note
: Examine each bank of DIP switches carefully to note the switch
direction for ON or OFF.
Table 2-1. CPU/System Controller Board Switch SW1
SW1 Setting Function Mode

defaults)
Note: Setting both switch 3 and switch 8 to OFF (closed)
sets all serial communication ports to 9600 bps
operation. All serial communication ports must be
set at 9600 bps before WINDIAG can perform
communication tests.
4 Core Updump Causes the ControlWave ExpressPAC to perform a core
updump, provided you have set the SW1 switches to allow
recovery mode. Values are:
