NPort Server Pro User’s Manual 4-15
Server Properties—Transmission
The Transmission page allows the user to set the Transmission Mode and Tx FIFO options for
each of NPort Server Pro’s ports.
Transmission Mode
Select Hi -Performance to use buffering
technology to accelerate data writing. This
allows your communication software to
reach maximum data throughput when
transmitting large amounts of data. The
driver will notify the user that the
transmission is complete when the output
data length is lower than the LOW
WATER setting.
Classical Mode lets the port behave like a
generic COM port. Transmission of small
data packets is more precise and reliable. In
this case, the driver will notify the user that
the transmission is complete when all data
has been transmitted.
Tx FIFO
Set to Enable to the get the best performance from the board.
Set to Disable to avoid data loss when communicating with plain communication devices using S/W
flow control. In this case only one byte will be put into the UART when the FIFO is empty.
