Connecting a User Port to an External Unit
To connect one of the RTU RS232 ports defined as a User port to an external unit (which
supports RS232), you may use one of the two adaptors (FLN6457B or FLN6458B) according
to the port definition in the site configuration.
If the FLN6457B adaptor is used, refer to the pin assignment given in Connection to a
Computer or Terminal in this chapter.
If the FLN6458B adaptor is used, refer to the pin assignment given in Connection to a Modem
in this chapter.
