Flexible Serial Port
Programmer Port
The T2E/T2N’s RS-232C programmer port supports the open T-sprles computer linK protocol as well as the
proprietary programmer protocol. This próvidas an easy connection to a higher level computer, an operator
interface unit, a modem, etc.

Communication Port on the CPU Module
The RS-232C or RS-485 multi-purpose communication port is standard on the T2N CPU. The interface is
selected by a DIP switch.
The RS-232C or RS-4S5 multi-purpose communication port is an option on the T2E CPU. A CM231E or
CMI232E card must be mounted in the T2E CPU module.
By using these communication port, one of the follow'lng three communication modes is available.
Computer link mode
T-sertes computer link protocol can be used in this
mode. When the RS-485 is used, a maximum of 32
T2E/T2NS can be connected to a master computer.
By using this mode, all the T2E/T2N's data can be
accessed by a master computer.
The T-series PLC programming software fT-PDS}
can also he used in this configuration.
