Connection to a PC by the Host Link Section 2-4Connecting to C Series CPM1When a connector cable of 5 m or longer is requiredWhen Long-Distance Transmission is Required2-4-3 PC Switch SettingsThe CPM1 is connected via an RS-232C adapter (type CPM1-CIF01).Procure an RS-232C 9-pin type connection cable for the connection.When a connector cable of 5 m or longer is required, please make the cable. However,note that the maximum transmission distance is 15 m.To make a connector cable, refer to Appendix E Method for Making the Cable forConnection to the PC/Host (page 265).When transmission over a distance exceeding the RS-232C specification is required,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 cannot beused).For details, refer to “Appendix F Connecting to an RS-232C/RS-422A converterunit” (page 277 of the appendix).When the NT600S and PC are connected to each other, set the conditions at thePC host link unit or the CPU as given in the table below.The following is a general description of switch settings.Refer to the manual for respective units for the details of the switch settings.ItemSwitch SettingI/O portRS-232CBaud rate Set the same baud rate as the NT600S.

Set the host link baud rate at 9600 bps or 19200 bps with the memory switchfor “host link baud rate”. For the details, refer to “Selecting the Host Link CommunicationSpeed” (page 86).*2. The 1-to-N setting enables BCC (Block Check Character). The 1-to-N connectioncannot be used to connect the NT600S to a host link unit.When using CVM1/CV series, always set “CPU execution processing (executioncontrol 2)” in the PC system settings to “Simultaneous processing”.34ηττπ://νιχοντρολσ.χοm
