Yes: Connection is possible. No: Connection is not possible.
Note: Only when a Controller Link Interface Unit (NS-CLK21) is mounted.
• When there are multiple serial ports and Ethernet Units for a single host, each port can
be used to communicate with separate PTs. This type of communications method,
however, will reduce the communications performance at the host.
