Connecting RS232C Equipment through RS232C Port 1 or 2

When using port 2 for RS232C communication on the all-in-one 16- or 24-I/O type CPU module, install the RS232C com-
munication adapter (FC4A-PC1) to the port 2 connector.
When using port 2 for RS232C communication on the slim type CPU module, mount the RS232C communication module
(FC4A-HPC1) next to the CPU module.
When using port 2 for RS232C communication on the slim type CPU module with the optional HMI module, install the
RS232C communication adapter (FC4A-PC1) to the port 2 connector on the HMI base module.
To connect an RS232C communication device to the RS232C port 1 or 2 on the
communication cable 1C (FC2A-KP1C). One end of the user communication cable 1C is not provided with a connector,
and can be terminated with a proper connector to plug in to communicate with the RS232C port. See the figure on
page 17-3.
