There is a PS Monitor board installed in each PA cabinet to control and monitor the
supplies and to report back to the Main Controller in the #1 PA Cabinet. Dipswitch
S1 has 8 switches, which are used to set the cabinet ID and to configure the board so
that it knows how many and what type of supplies it is monitoring. Table 4-2 shows
the settings for all sections of S1. The switches set the following parameters:
a. Cabinet ID - The number of the PA cabinet (1-8)
b. Single or dual low voltage power supplies (LVPS)
c. 3 phase or single phase power
d. Number of PA power supply modules
