Note:
1.With RS-232C communications, free-run mode is supported for SD and RD but not for any other signal lines.
2.To use USB communications, the USB driver for the K3SC must be downloaded from the OMRON web site.
http://www.fa.omron.co.jp/
3.The enclosure ratings do not apply when USB is used.
4.The CE marking does not apply when the K3SC is used for USB.
Caution: In the interenst of product improvement, specifications are subject to change without notice.
