RS-422A Adapter (NT-
AL001)
Connecting to the Host’s RS-232C Port
The Type of Host and Settings
Reference:
Note
One end of the wire must always be connected to the host (PLC), and there
must be no branching. Branching will cause problems such as transmission
delays and communications failures.
CS/CJ-series CPU Units cannot be connected with the 1:1 connection NT link
method. Use the 1:N connection NT Link method (standard or high-speed) in-
stead to make the 1:1 connection. For details, refer to Using the NT link (1:N)
method (page 64) or Using the High-speed NT link (1:N) method (page 69).
The using condition is the same as the connecting PT side RS-232C and the
host side RS-232C.
For the available type and settings of the host, refer to the pages listed below.
When making a connection between RS-232C and RS-422A/485 ports using
an RS-232C/RS-422A Adapter, set the DIP switches on the NT-AL001 as fol-
lows.
