Connections to Serial Communications Option Boards
Appendix F
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 being connected to confirm support.
(2) The CP1W-CIF11 is a non-isolated board, so the maximum transmission distance is 50 m. For dis-
tances over 50 m, use the RS-232C port on the CP1W-CIF01 and then connect through the NT-
AL001-E Link Adapter, which is isolated. Doing so will enable a maximum transmission distance of
500 m.
(3) The maximum cable length is limited to 2 m when an NT-AL001-E Link Adapter is connected.
(4) Branch lines must be a maximum of 10 m long.
Connection Examples
The connection examples in the remainder of this section show only the basic connection diagrams. We rec-
ommend that appropriate noise countermeasures be taken in actual applications, including the use of shielded
twisted-pair cables. Refer to
3-4 RS-232C and RS-422A/485 Wiring
for actual wiring methods.
