8-3
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.
Port Data Buffering/Log
The NPort 6000 supports port buffering to prevent the loss of serial data when the Ethernet
connection is down. Port buffering can be used in TCP Server mode, TCP Client mode, and Pair
Connection mode. For other modes, the port buffering settings will have no effect.
Port buffering enable (default=No): You may enable port buffering by setting this field to Ye s.
Port buffering location (default=Memory(64K)): If port buffering is desired, use this setting to
configure whether the buffer is located in the system memory or in an optional installed SD card.
Install and use an SD card if a buffer size greater than 64 KB is desired. Note that optional SD
cards are not supported on the NPort 6150.
Port buffering SD file size (default=1 Megabyte): Use this field to configure the size of the port
buffer if you have configured it to reside on an SD card. Note that optional SD cards are not
supported on the NPort 6150.
Serial data logging enable (default=No): If this field is set to Yes, the NPort 6000 will store data
logs on the system RAM for all serial ports. Note that this data is not saved when the NPort 6000
is powered off. Each serial port is allotted 64 KB to store that port’s log file.
