JARC Board DIP Switch
Positions 9, 10, and 11 of DIP switch SW1 determine the starting rack number
for the JARC board to accept on the network (see Table 3). This rack number
must match the lowest rack number selected on the SmartMUX board. The
SmartMUX board is usually wired to JARC board connector J5. Rack 0 is only
valid for a PLC-3.
