In some cases, the number of units, transmission distance, and baud ratevary depending on the connected device.(Note 4) When communication is performed at a baud rate of 38400 bps or higher, use the cable not longer than 3 m.For wiring the 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-485setting. When using a baud rate of 38400 bps or less, the allowable settings are a maximum of 1200 m and 99units. When a C-NET adapter is mixed, the maximum number of connected units is 32, and the baud rate islimited to 19200 bps or less.(Note 6) The converter SI-35 manufactured by Lineeye Co., Ltd is recommendable for the RS485 at the computer side.(Note 7) In general-purpose communication, RS-232C and RS-422 use full-duplex transmission.Phone: 800.894.0412 - Fax: 888.723.4773 - Web: www.clrwtr.com - Email: info@clrwtr.com
