Important: Do not to change these switch settings if you have them. In
the later (series B) versions of the KP3 MAC board, changes were made
to the hardware, making the need for this MAC switch unnecessary.
There are four thumbwheel switches on the KP3’s front panel. Use the
one at the top of the module (figure 2.5) to set the KP3’s module number.
This number distinguishes it from other KP3 modules in the chassis. You
should start with the number 1 and as you add KP3 modules to the
chassis, go to the next highest consecutive number.
Important: If you are using the KP3 in a backup system make sure the
module numbers in the primary and backup KP3s are the same.
