Connection Methods
Communications Modes and Ports
The following table shows the relationship between the communications ports and the communications modes
for the Serial Communications Option Boards.
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.
(2) Use 4-wire connections between Link Adapters.
Models of Serial Communications Option Board
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.
