CJ1M-CPU1@-ETN
External Interface
A CJ-series CJ1M CPU Unit (with Ethernet function) provides three communications ports (a peripheral port, an RS-232C port and Ethernet
connectors).
Peripheral port
The peripheral port is used to connect a Programming Device (including a Programming Console) or a host computer. It can also be used as an
RS-232C port by connecting a suitable cable, such as the CS1W-CN118 or CS1W-CN@26. The connector pin arrangement when using a
connecting cable for an RS-232C port is shown below.
