3-5-2 Connecting the NT600S
Refer to the illustrations below to select the appropriate cable for the unit connec-
tors and connect the NT600S to the PC.
A host link connector cable can also be used. To make a connector cable, refer to
Appendix E Method for Making the Cable for Connection to the PC/Host (page
264).
 After connecting a communication cable, always secure it 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.
Before inserting or removing the connectors, make sure that the NT600S and the
PC are turned OFF.
Use a connector cable with a 9-pin connector on both ends to connect the NT600S
to a PC with a 9-pin connector.

The following are the recommended cables (manufactured by OMRON).
Connector Specification Model Cable Length
9pin  9pin
XW2Z-200T 2 m
9pin  9pin
XW2Z-500T 5 m
If a Cable Longer Than 5 m is Required
If a cable longer than 5 m is required, a connector cable will have to be made. Refer
to Appendix E Method for Making the Cable for Connection to the PC/Host (page
264).
The maximum transmission distance is 15 m.
When Long-Distance Transmission is Required
When transmission over a distance exceeding the RS-232C specification is re-
quired, it can be achieved by using an RS-232C/RS-422A converter unit (type NT-
AL001) to switch to RS-422A communication (RS-485 communication cannot be
used).
For details, refer to “Appendix F Connecting to an RS-232C/RS-422 Converter
Unit” (page 275 of the appendix).
