A-4-2 Connection Examples
Note 1 The maximum cable length for an RS-232C connection is 15 m. RS-232C communications specifications,
however, do not cover transmissions at 19.2 Kbps. Refer to documentation of the device being connected
when using this baud rate.
2 The CP1W-CIF11 RS-422A/485 Option Board is not isolated. The maximum transmission distance is
therefore 50 m. If the distance exceeds 50 m, use the isolated CP1W-CIF12, or connect the isolated NT-
AL001 RS-422A Link Adapter to the RS-232C port on the CP1W-CIF01 RS-232C Option Board. If you use
one of these methods, the maximum total transmission distance will be 500 m.
3 The maximum cable length for connecting to the NT-AL001 is 2 m.
4 The maximum branch cable length is 10 m.
