Addressing Dipswitch Configuration for Network Communication

For proper communication, a unique address must be configured on each controller by setting the first 7 switches on the
addressing dipswitch to the desired value.
These switches are numbered from 1 to 7 and represent a binary value from 1 to 64 (1, 2, 4, 8, 16, 32, and 64 respectively).
The last switch (#8) is reserved. The value of each switch that is in the ON position is added together to form the numer-
ical address of the controller.
The example in Figure 9 shows the switches 1, 2 and 4 in the ON position. Therefore, the corresponding values are 1, 2
and 8, giving an address sum of 11.
The Prolon network allows a maximum of 127 addresses; therefore 127 controllers.
