Connect NT620S/NT620C units to an OMRON PC in a 1:N connection by using
the NT link method.
To do this, the communication conditions must be set with the memory switches.

(Refer to "Setting the Host Communication Method" (page 70)
S Setting the unit No. of the connected NT620S/NT620C
(Setting Unit Numbers (NT Link 1:N Only) (page 74))
With NT link (1:N), both RS-422A type (4-wire) and RS-485 type (2-wire) connec-
tions are possible. The NT link (1:N) cannot be used with the system programs
installed in NT620S-ST211(B) and NT620C-ST141(B) on shipment. The system
program must be changed by using the NT620-ZS3AT-EMV system installer.
The only OMRON PCs that can be connected in an NT link (1:N) are the C series
C200HX/HG/HE models.
When making a connection, check the series and model of the PC to which the
connection is being made, and the type of CPU unit that is installed. The follow-
ing is a list of the PCs that can be connected to the NT620S/NT620C via an NT
link (1:N).

Referring to the illustrations below and using a cable appropriate for the CPU
unit's connector, connect the NT620S/NT620C units and the PC using RS-232C/
RS-422 converter units (type NT-AL011).
A host link connection cable can be used as the RS-232C cable. For details on
making a connection cable, refer to Appendix G "Method for Making the Cable for
Connection to the PC" (page 301 of the appendix).
- After connecting the communication cable, be sure to lock the connectors with
the screws. Otherwise the cable may disconnect, causing operation to fail.
- The cable's tensile load is 30 N. Do not subject it to loads greater than this.
Otherwise a discontinuity may occur, causing operation to fail.
Read the instruction manual provided with the NT-AL001 carefully.
