STEP 4: Configure serial communication parameters
This step covers the configuration of each device port’s serial communication parameters, such as
baudrate, stop bit, etc.
This step requires the following items:
 NPort 5600-8-DT Series device server with live connection to the network
 Windows PC with live connection to the same network and NPort Administrator installed
Make sure that NPort Administrator is open with your device server listed in the configuration
pane. You should also know the serial communication parameters for the attached device and
intended application.
Review Serial Parameters
The following parameters need to be set correctly on the device port for proper communication
with your device. Please refer to your device’s documentation for the appropriate settings.
Parameter Options Description
Baudrate
50 bps
115.2 Kbps (default)
921 Kbps
This is the rate of data transmission to
and from the attached serial device.
Data bits
5
6
7
8 (default)
This is the size of each data character.
Stop bits
1 (default)
1.5
2
This is the size of the stop character.
Parity
None (default) Even
Odd
Space
Mark
This is the kind of parity that will be
used. Even and Odd parity provide
rudimentary error-checking; Space and
Mark parity are rarely used.
Flow control
None
RTS/CTS (default)
DTR/DSR Xon/Xoff
This is the method used to suspend and
resume data transmission to ensure that
data is not lost. RTS/CTS (hardware)
flow control is recommended if
possible.
FIFO
Enable (default)
Disable
This controls whether the device port’s
built-in 128-byte FIFO buffer is used.
When enabled, the FIFO helps reduce
data loss regardless of direction.
Interface
RS-232
RS-422
RS-485-2W
RS-485-4W
This is the serial interface that will be
used. The options that are available
depend on the specific model of device
server.
