In the Basic Settings tab,
select the COM port number
that will be mapped to the
device port. You can map
multiple COM ports at the
same time, in which case the
“Auto Enumerating” feature
may be used to automatically
number the COM ports.
In the Serial Parameters tab,
adjust the settings to match
your device. These settings
must also match the settings
on the device port. Click
“OK” when you are satisfied
with your changes.
Advanced Settings
For additional details on Advanced Settings in NPort Administrator, please refer to Chapter 8.
Tx Mode: In Hi-Performance mode, the driver immediately issues a “Tx Empty” response to the
program after sending data to the NPort. In Classical mode, the driver sends the “Tx Empty”
response after confirmation is received from the NPort. Classical mode is recommended if you
want to ensure that all data is sent out before further processing.
FIFO: This tells the driver whether or not to use the FIFO.
Network Timeout: This specifies when an open, close, or serial parameter change operation will
time out.
Fast Flush: When enabled, the driver flushes only the local buffer on the host for a Win32
PurgeComm() function call. When disabled, both the local and remote buffers are flushed. If
your application uses PurgeComm() and performance seems sluggish, try enabling Fast Flush.
