Configuring Serial Communication Parameters - Moxa Technologies 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.

*Supported interfaces vary by model; refer to your NPort's datasheet for a list of supported serial
interfaces.

Factory Default Description
The data transmission rate to and from
115200 bps
the attached serial device.
8 The size of each data character.
1 The size of the stop character.
The parity that will be used. Even and
Odd parity provide rudimentary error-
None
checking; Space and Mark parity are
rarely used.
The method used to suspend and
resume data transmission to ensure
RTS/CTS that data is not lost. RTS/CTS
(hardware) flow control is
recommended.
Controls whether the device port's
built-in 128-byte FIFO buffer is used.
Enable
When enabled, the FIFO helps reduce
data loss regardless of direction.
The serial interface that will be used.
RS-232 The options that are available depend
on the specific model of device server.
