Port Communication Parameters
Port alias: This optional field allows you to assign an alias to a port for easier identification.
Serial Parameters
ATTENTION
The serial parameters for the each serial port on the NPort 6000 should match the parameters used by the
connected serial device. You may need to refer to your serial device’s user’s manual to determine the
appropriate serial communication parameters.
Baud rate (default=115200 bps): This field configures the port’s baudrate. Select one of the standard
baudrates from the dropdown box, or select Other and then type the desired baudrate in the input box.
ATTENTION
If the port requires a special baudrate that is not listed, such as 500000 bps, you may can select the Other
option and enter the desired baudrate into the text box. The NPort 6000 will automatically calculate the
closest supported baudrate. The margin for error will be less than 1.7% for all baudrates under 921600 bps.
Data bits (default=8): This field configures the data bits parameter. Note: If data bits is set to 5 bits, stop bits
will automatically be set to 2 bits.
Stop bits (default=1): This field configures the stop bits parameter. Note: If data bits is set to 5 bits, stop bits
will automatically be set to 1.5 bits.
Parity (default=None): This field configures the parity parameter.
Flow control (default=RTS/CTS): This field configures the flow control type.
FIFO (default=Enable): This field enables or disables the 128-byte FIFO buffer. The NPort 6000 provides FIFO
buffers for each serial port, for both the Tx and Rx signals. Note, however, that you should disable the port’s
FIFO setting if the attached serial device does not have a FIFO buffer of its own. This is because a serial device
that does not have its own buffer may not be able to keep up with data sent from the NPort’s FIFO buffer.
Interface (default=RS-232): You may configure the serial interface to RS-232, RS-422, RS-485 2-wire, or
RS-485 4-wire.
