For cable parts and the wiring method, refer to APPENDIX G Method for Making
the Cable for Connection to the Host (page 256).
Use a cable that is compatible with the RS-232C connector of the host to connect
the NT20S and the host (see the example in the figure below).
In the example shown here, the cable connects the 9-pin connector of the NT20S
and 25-pin connector of the host. If the host has a 9-pin RS-232C connector, use
an RS-232C cable with 9-pin connectors at both ends.
S When making the connection, switch off the power to the NT20S and PC before
S After connecting the communication cable, always secure it with the screws.
If using the +5 V supply of pin No.6, check first that the equipment that is to receive
the supply has a current capacity no greater than 150 mA. The +5 V output of the
NT20S is +5 V DC 5%, max. 150 mA.
