Modem initialization
(Note 1): The AFPX-COM1 is a 5-wire type. When using it as a 3-wire type, short-circuit the RS-CS terminal.
(Note 2): It can be switched between RS-485 and RS-422 by switching the dip switches on the cassette.
(Note 3): When connecting a commercially available device that has an RS485 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 the cable not longer than 3 m.
For wiring the RS232C, a shielded wire must be used to increase noise suppression.
(Note 5): The transmission distance is limited by the baud rate and the number of connected units when setting RS-
485 as follows. 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.
(Note 6): The converter SI-35 manufactured by Lineeye Co., Ltd. is recommendable for the RS-485 at the computer
side.
(Note 7): For information on usable functions and restrictions on the combination, refer to 1.4.4 Restrictions on
Communication Function.
