3-6 Connection to a PC by the NT Link (1:N)
Connect the NT600S to an OMRON PC by the NT link method.
To connect the NT600S to a PC by the NT link (1:N) method, the communication
conditions must be set with the memory switches.
Setting NT link (1:N)
(Refer to “Selecting the Host Communication Method” (page 85))
Setting the unit No. of the connected NT20S
(Selecting Unit Numbers (page 87))
3-6-1 Compatible PCs
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 host link unit that
is installed.
The following is a list of the PCs that can be connected to the NT600S via a host
link (1:N).

3-6-2 Connecting the NT600S Units
Referring to the illustrations below and using a cable appropriate for the CPU unit’s
connector, connect the NT600S units and the PC using RS-232C/RS-422A con-
verter units (type NT-AL001).
An NT link connection cable can be used as the RS-232C cable. For details on
making a connection cable, refer to Appendix E “Method for Making the Cable for
Connection to the Host” (page 264).
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.
