Switch assemblies SW-3 and SW-4 are for setting the node number of the
1785-KE module. The node number is an encoded 2-digit octal number
that identifies the Series A module as a unique node on Data Highway
Plus. Valid node numbers for the Series A module are 00 to 77 octal.
Figure C.4 shows you how to set the node number using switch assemblies
SW-3 and SW-4. Use the switches in assembly
SW-3 to set the first (left-most) digit
SW-4 to set the second (right-most) digit.
