NPort W2150A/W2250A Series Web Console: Serial Port Settings
8-17
When Operation Mode is set to UDP on a serial port’s Operation Modes page, you will be able to
configure additional settings such as Destination address 1 through 4, Local listen port, Packet length,
Delimiter 1, Delimiter 2, Delimiter process, and Force transmit.
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 four 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
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.
ATTENTION
When Delimiter 1 is enabled, Packet length must be set to 0.
