External Interface
A CJ2H CPU Unit (CJ2H-CPU6
@
-EIP) provides three communications ports for external interfaces: a peripheral (USB) port, a sirial 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 on the CPU Unit for anything but the NT-AL001-E Link Adapter. The external
device or the CPU Unit may be damaged.
