Note	1. FG is not connected internally in the NT600S.

2.Unlisted pins are not used.

For cable parts and the wiring method, refer to APPENDIX E Method for Making the Cable for Connection to the PC/Host (page 264).

Connecting to the Host Computer

Use a cable that is compatible with the RS-232C connector of the host to connect the NT600S and the host.

In the example shown here, the cable connects the 9-pin connector of the NT600S 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.

Caution Turn off the NT600S power supply when connecting or disconnecting connec- tors.

￿After connecting a communication cable, always secure it with the screws.

Check that the current capacity of the equipment to be supplied is within 150 mA before using the +5V output of pin No.6. Otherwise, the product may malfunc- tion.

The current capacity of +5 V output of NT600S is:

+5 V 5%, 150 mA max. with ST211(B)-EV , and +5 V ￿5%, 100 mA max. with ST121(B)-EV￿.
