Method for Making the Cable for Connection to the PC
Connecting an NT620S/NT620C to a C-Series C200HS, C200HX/HG/HE, CPM1, CQM1, or CVM1/CV-Series
(-EVj) CPU (Including Communication Board)
S C-series C200HS, C200HX/HG/HE, CPM1, CQM1, CVM1, CVM1/CV series (-EVj) CPU
unit 9-pin connector specifications
Applicable CPU units:
CPM1-10CDR-j CQM1-CPU21-E
CPM1-20CDR-j CQM1-CPU41-E
CPM1-30CDR-j CQM1-CPU42-E
Note The host link function incorporated in CV/CVM1 CPUs (with the exception of -EVj) cannot be used.

The NT620S/620C does not use pin 4 (RS) or pin 5 (CS). Either short the RS and CS pins of the PC connector
together or set the CTS setting selector switch at the rear face of the host link unit to "0V" (see < in the figure).
