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.
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
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.
