CJ-series Serial Communications Units Operation Manual for NJ-series CPU Unit(W494)
Note 1
The maximum cable length for RS-232C is 15 m. The RS-232C standard, however, does not
cover baud rates above 19.2 Kbps. Refer to the manual for the device connected to confirm
support.
2
The total cable length for RS-422A/485 systems, including branch cables, is 1,200 m max. The
total cable length for RS-422A/485 systems, including branch cables, is 500 m max. when NT-
AL001 Link Adapters are used. The baud rate and the communications distance sometimes
depend on the remote device. Confirm the baud rates and communications distance sup-
ported by connected devices.
3
Here, the maximum cable length is limited to 2 m when an NT-Link Adapter is connected.
4
Branch lines must be a maximum of 10 m long.
