Web Console: Serial Port Settings
7-23
Destination Address 1 to 4
Default
Options
IP address range and port (e.g., “192.168.1.1” to “192.168.1.64” and “4001”)
Description
In UDP mode, you may specify up to 4 ranges of IP addresses for the serial port
to connect to. At least one destination range must be provided.
The maximum selectable IP address range is 64 addresses. However, you can
enter multicast addresses in the Begin field, in the form xxx.xxx.xxx.255. For
example, enter “192.127.168.255” to allow the NPort to broadcast UDP packets
to all hosts with IP addresses between 192.127.168.1 and 192.127.168.254.
Local Listen Port
Default
4001
Options
0 to 9999
Description
This field specifies the UDP port that the NPort listens to and that other devices
must use to contact the attached serial device.
Packet Length
Default
0
Options
0 to 1024
Description
This field specifies the maximum amount of data that is allowed to accumulate
in the serial port buffer before sending.
0: Packet length is disregarded and data in the buffer will be sent as specified by
the delimiter settings or when the buffer is full.
1 to 1024: Data in the buffer will be sent as soon it reaches the specified length.
Delimiter 1 and 2
Default
Disabled
Options
Disabled, Enabled, 00 to FF
Description
These fields are used to define special delimiter character(s) for data packing.
Enable Delimiter 1 to control data packing with a single character; enable both
Delimiter 1 and 2 to control data packing with two characters received in
sequence.
When these fields are enabled, serial data will accumulate in the serial port’s
buffer until the buffer is full or until the specified delimiter character(s) are
received. For example, the carriage return character could be used as a delimiter
in order to transmit each sentence or paragraph in a separate packet. Data will
be packed according to Delimiter process.
Delimiters must be incorporated into the data stream at the software or device
level.
