Communications Modes and Ports
The following table shows the relationship between the communications ports and the communications modes
for the Serial Communications Option Boards.
Communications mode
Host Link
Serial PLC Links
Serial Gateway
No-protocol
1:N NT Link
1:1 NT Link
1:1 Link Master
1:1 Link Slave
Note (1) The NT-AL001-E Link Adapter can be used to convert between RS-232C and RS-422A/485 to en-
able 1:N communications.

Models of Serial Communications Option Board
Model
CP1W-CIF01 One RS-232C port
CP1W-CIF11 One RS-422A/485 port
Note The CP1W-CIF11 is a non-isolated board, so the maximum transmission distance is 50 m. For distances
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.
