IOM ADDRESS SET UP
Each IOM should have its own
address. The address could range
from 1 to 127. Never use zero as
IOM address as zero is reserved
for the master device.
Note: It is recommended not to
attach more than 4 IOM units to the
RS485 bus to maintain a
reasonable signal/response time
delay between the reader and
IOMs. Hence IOM addresses must
be from 1 to 4 only.

To work out the address, select a
combination of bit locations on the
DIP switch. Each bit has its own
value representation. The RS485
address is obtained by adding all
ON-bit values. E.g. Decimal value
37 will be obtained by turning ON
bits 1, 3 and 6 which equivalents to
1+4+32.
