– Select this option when it is required to execute a process that returns to Duplex
Operation automatically.
Communications Unit Duplex Setting
From the list of Communications Units select those that are to be run in duplex mode. If more than one Unit is
set to duplex mode the options selected will be applied to each Unit. It is not possible to set different options
for different Communications Units. To execute the Communication Duplex operation an IO table must be
