(Note 1) The AFPX-COM1 is a 5-wire type. When using it as a 3-wire type, short-circuit the RS and CS
terminals.
(Note 2) By using the DIP switch on the cassette, you can switch between RS-485 and S-422.
(Note 3) When connecting a commercially available device that has an RS-485 / RS-422 interface, confirm
operation using the actual device. In some cases, the number of units, transmission distance, and
baud rate vary depending on the connected device.
(Note 4) When communication is performed at a baud rate of 38400 bit/s or higher, use a cable not longer than
3 m. When wiring RS-232C, a shielded wire must be used to increase noise suppression.
(Note 5) The transmission distance is limited as shown below by the baud rate when set to RS-485 and the
number of connected units. For the baud rate of 38400 bit/s or less, the distance is up to 1200 m, and
the number of connected units is 99. When using in combination with the C-NET adapter, the
maximum number of connected units is limited to 32, and the baud rate is limited to 19200 bit/s or
less.
