Modem initialization
(Note 1): AFP0HCCS1 is a 5-wire type. When using it as a 3-wire type, short-circuit the RS-CS terminals.
(Note 2): When connecting a commercially available device that has an RS-485 interface, please confirm operation
using an actual device. In some cases, the number of units, transmission distance, and baud rate vary
depending on the connected device.
(Note 3): 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 4): The transmission distance is limited as follows by the baud rate and the number of connected units when
setting RS-485. For the baud rate of 38400 bit/s or lower, the max. distance is 1200 m, and the max. number
of connected units is 99. When using in combination with a C-NET adapter, the max. number of connected
units is limited to 32, and the baud rate is limited to 19200 bit/s or lower.
