3-8 Host Connections by RS-232C

Connect NT600S with an RS-232C Interface Unit installed to the host computer with an RS-232C cable.

RS-232C connection allows a single NT600S to be connected to the host.

A computer or other control device with a built-in RS-232C interface is a suitable host for connection to the NT600S.

Reference To connect the NT600S to a Host by the RS-232C method, the NT600S memory switch for “Comm. Method” must be set to “RS-232C” and the communication set- tings must be set for RS-232C communications. For the “Comm. Method” setting, refer to “Selecting the Host Communication Method” (page 85), and for the memory switch setting for RS-232C communication, refer to “Setting the RS-232C Communication Conditions” (page 89).

3-8-1 Host Computer Communication Settings

Set the host communication conditions according to the following table.

Item

Setting

 

 

Baud rate

Set to the same baud rate as the NT600S: 2400, 4800, 9600,

 

19200

 

 

Data bits

7 bits/8 bits

 

 

Stop bits

1 bit/2 bits

 

 

Parity

Even, Odd, None

 

 

Flow control

RS/CS control

 

XON/XOFF control

 

None

 

 

 

 

Reference Set the same communication conditions at the NT600S and Host.

Refer to the appropriate instruction manuals for the method of setting the Host communication conditions.

You are recommended to set the maximum baud rate supported by both the

NT600S and Host.

3-8-2 Connector Pin Arrangement

The RS-232C connection between the NT600S and Host is described below.

RS-232C Interface Unit The connector and cable specifications are described below. Electrical characteristics: Conforms to EIA RS-232C specifications. Signal direction: Signal input and output are relative to the host computer.
