Connecting Link Adapters and RS-422A Converters
This section describes the installation of the NT-AL001 Link Adapter and
CJ1W-CIF11 RS-422A Converter, including the external dimensions, proce-
dure for mounting and removal, and specifications. Refer to this information
when designing the control panel. For further details, refer to the
Instruction
Sheet
supplied with the NT-AL001 or CJ1W-CIF11.
2-3-1
Connecting an CJ1W-CIF11 RS-422A Converter
The CJ1W-CIF11 RS-422A Converter connects directly to the NT20’s serial
port A or B and converts RS-232C communications to RS-422A or RS-485.
The NT20 supplies power to the RS-422A Converter through pin 6 of the RS-
232C connector, so an external power supply is not required.
Note
1.
The RS-232C connector is not insulated from the RS-422A/RS-485 con-
nector within the CJ1W-CIF11 RS-422A Converter. If there are concerns
about differences in ground potential or noise, we recommend using the
NT-AL001 Link Adapter.
2.
Always turn OFF the NT20’s power supply before installing/removing a RS-
422A Converter or connecting/disconnecting cables.
3.
Always discharge any static electricity by touching a grounded object be-
fore installing the RS-422A Converter or connecting cables.
