Connecting to the Host’s RS-232C Port Section 5-1
Wiring for a Memory Link Connection
Prepare the adapter cable while referring to the diagram shown below.
Since it is necessary to input a voltage of +5 V to the number 6 pin of NT-
AL001, supplying a voltage of 5 V from the host or an external voltage supply
for NT-AL001 is required.
5-1-3 1:N Connection between RS-422A/485 at the PT and RS-232C at
the Host
The connection method in which the RS-422A/485 ports of multiple NT31/
NT31Cs are connected to the RS-232C port of one host in a 1:N connection is
described here.
An RS-232C/RS-422A Adapter (NT-AL001) is used to convert between the
RS-232C and RS-422A/485 communications methods.
(9-pin type)
Shielding wire
No +5 V output is at the host side
