Note 1. The node number of the 32-point Slave must be set to an even number. If
an odd number is input, the odd number less one will be set in the Slave.
2. The possible range of node numbers varies with the type of Master and
settings in the Master. Refer to 2-1 Communications Specifications for de-
tails.
Communications Mode Settings
The following communications modes are set with pin 3 of the DIP switch.
Note Make sure that the communications mode of the Slave is the same as that of
the Master Unit. If the communications modes are not the same, normal com-
munications with the Master Unit will not be possible. The operating status of
the Slave can be verified with LED indicators. Refer to 6-5-1 Indicators.
