2-6-2 Connecting the NT620S/620C
Refer to the illustrations below to select the appropriate cable for the unit connec-
tors and connect the NT620S/620C to the PC.
A host link connector cable can also be used. To make a connector cable, refer to
Appendix G “Method for Making the Cable for Connection to the PC” (page 301).
Caution
Before inserting or removing the connectors, make sure that the NT620S/620C
and the PC are turned OFF.
RS-232C Cable
Use a connector cable with a 9-pin connector on both ends to connect the
NT620S/620C to a PC with a 9-pin connector.

2 m
Caution
- 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.
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 G “Method for Making the Cable for Connection to the PC”
(page 301).
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 can-
not be used).
For details, refer to Appendix I “Connecting to an RS-232C/RS-422 Converter
Unit” (page 315 of the appendix).
