NPort 5000 Series User Manual
Configuring Serial Communication Parameters
This section covers the configuration of each device port’s serial communication parameters: baudrate, stop
bit, etc.
Serial Parameter Review
The following parameters need to be set correctly on the device port to ensure proper communication with
your device. Refer to your device’s documentation for the appropriate settings.
Baudrate
baudrates (bps):
300/ 600/ 1200 1800/
2400/ 4800/ 7200/
9600/ 19200/ 38400/
57600/ 115200/
230.4k/ 460.8k/
921.6k
* The NPort
Series, and IA 5000
Series are as low as
110 bps, and up to
115200 bps
The data transmission rate to and from
the attached serial device.
Required
The size of each data character.
The size of the stop character.
Parity
None, Even, Odd,
Space, Mark
None
The parity that will be used. Even and
Odd parity provide rudimentary error-
checking; Space and Mark parity are
rarely used.
Required
Flow control
None, RTS/CTS,
DTR/DSR, Xon/Xoff
RTS/CTS
The method used to suspend and
resume data transmission to ensure
that data is not lost. RTS/CTS
(hardware) flow control is
recommended.
Required
FIFO Enable, Disable Enable
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.
Required
Interface*
RS-422
2-wire RS-485
4-wire RS-485
RS-232
The serial interface that will be used.
The options that are available depend
on the specific model of device server.
Required
*Supported interfaces vary by model; refer to your NPort’s datasheet for a list of supported serial
interfaces.
