Connecting to C Series CPM1

The 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

When a connector cable of 5 m or longer is required, please make the cable. How- ever, note that the maximum transmission distance is 15 m.

To make a connector cable, refer to Appendix E Method for Making the Cable for

Connection to the PC/Host (page 264).

When Long-Distance Transmission is Required

When transmission over a distance exceeding the RS-232C specification is re- quired, 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 be used).

For details, refer to “Appendix F Connecting to an RS-232C/RS-422A converter unit” (page 275 of the appendix).

3-4-3 PC Switch Settings

When the NT600S and PC are connected to each other, set the conditions at the

PC 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.

Item	Switch Setting
I/O port	RS-232C
Baud rate	Set the same baud rate as the NT600S. (*1)
Transfer code	ASCII 7 data bits, 2 stop bits
Parity	Even
1-to-1/1-to-N	1-to-N (*2)
Instruction level	Level 1, 2, 3
Unit #	00

Note	*1.	Set the host link baud rate at 9600 bps or 19200 bps with the memory switch
		for “host link baud rate”. For the details, refer to “Selecting the Host Link Com-
		munication Speed” (page 86).
	*2.	The 1-to-N setting enables BCC (Block Check Character). The 1-to-N con-
		nection cannot be used to connect the NT600S to a host link unit.
Reference
	When using CVM1/CV series, always set “CPU execution processing (execution
	control 2)” in the PC system settings to “Simultaneous processing”.
