Custom Packetization
Custom packetization can apply to TCP and UDP communication. Unlike TCP, UDP is a
connectionless protocol. The SBL2e provides two methods to determine the destination network IP
address: you can specify a static IP address, or you can use the source IP address of the last received
UDP packet by selecting the “Learn UDP Reply Address” checkbox.

Check to enable UDP
Learn UDP reply Address
Send outbound serial to the IP address from the last
received UDP packet. Useful for clients that may have
changing IP addresses. If not using this feature, you
must specify the destination IP address and port
number in the Outgoing Connections section.
Number of characters to accumulate
before sending TCP/UDP packet
Maximum number of characters to accumulate from
the serial port before sending them out the network
port. This setting will be overridden if the
accumulation delay time setting is used and the delay
time expires.
Number msec to wait for accumulated
characters (0 waits forever)
Maximum wait time in milliseconds for received serial
characters before sending any available characters out
the network port.
Flush TCP frame when this character is
received (Enter NA to disable)
Send all accumulated serial data upon receipt of this
character from the serial port. Enter the decimal value
of the character. For example, a line feed is 10.
