System Setup
This section illustrates system setup configurations for using powerful communication functions of the MicroSmart.
User Communication and Modem Communication System
The all-in-one type MicroSmart CPU modules have port 1 for RS232C communication and port 2 connector. An optional
RS232C or RS485 communication adapter can be installed on the port 2 connector. With an RS232C communication
adapter installed on port 2, the MicroSmart CPU module can communicate with two RS232C devices at the same time.
Expansion RS232C/RS485 communication modules (FC5A-SIF2/-SIF4) can also be mounted to the CPU modules to add
port 3 to port 5, so that MicroSmart CPU module can communicate with more RS232C/RS485 devices at the same time.
The figure below illustrates a system setup of user communication and modem communication. In this example, the
operating status of a remote machine is monitored on a computer through modems connected to port 2 and the data is
transferred through port 1 to a pager transmitter using the user communication.
The same system can be set up using any slim type CPU module and an optional RS232C communication module.
For details about the user communication, see page 10-1.
For details about the modem mode, see page 21-1 (Advanced Vol.).
