SETTING THE SLAVE EXPANDER BUS ADDRESS
The FCS must have its slave expander bus address set to be
able to communicate with the processor module. The user can
select an address for the FCS from 0 to 63. The address is set
with switch SW1, an 8-pole dipswitch. Poles 1 and 2
must be
set to 0 (closed or on). Pole 3 has a binary value of 32. Pole 8 is
the least significant bit with a binary value of 1 (open or off).
See Figure
for the dipswitch location. Refer to Table
for
examples of address settings. Record your address in the user
setting column.
