External Interface

A CJ2H CPU Unit (CJ2H-CPU6

@-EIP) provides three communications ports for external interfaces: a peripheral (USB) port, a serial port and an

EtherNet/IP port.

Peripheral (USB) Port

Serial Port

* Baud rates for the RS-232C are specified only up to 19.2 kbps. The CJ Series supports serial communications from 38.4 kbps to 115.2 kbps,

but some computers cannot support these speeds. Lower the baud rate if necessary.

Note: Do not use the 5-V power from pin 6 of the RS-232C port for anything but CJ1W-CIF11 RS-422A Conversion Adapter, NT-AL001 RS-232C/

RS-422A Conversion Adapter and NV3W-M

@20L(-V1) Programmable Terminal. The external device or the CPU Unit may be damaged.
