IMPORTANT NOTE
A separate address must be assigned to
each IO board!
To differentiate between multiple IOPCBs in
an RS485 daisy chain, each IOPCB needs its
own address.
This can be set in the binary code using the
DIP switch (address switch).
If all four DIP switches are set to above,
the address is "1".
See Figure 16 for further addresses.
