Modem initialization
(Note 1) By switching on the dip switch on the cassette, you can use the unit as 5-wire 1-channel RS-232C.
(Note 2) By switching on the dip switch on the cassette, you can switch between RS-422 and RS-485.
(Note 3) When connecting a commercially available device that has an RS-485/RS-422 interface, please
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 by the specified baud rate and No. of connected units in the
RS-485 setting. When using a baud rate of 38400 bps or less, the allowable settings are a maximum
of 1200 m and 99 units. When a C-NET adapter is mixed, the maximum number of connected units is
32, and the baud rate is limited to 19200 bps or less.
(Note 6) The converter SI-35 manufactured by Lineeye Co., Ltd is recommended for the RS-485 at the
computer side.
(Note 7) In general-purpose communication, RS-232C and RS-422 use full-duplex transmission.
