3.3.1 Client Channel with UDP Protocol
For a channel in Client Mode, you must configure the IP address and Port of the server to which it
will connect. If you use an UDP Transport Protocol, that channel will transmit to that IP-Port the
information received by the serial and vice versa.
If the IP server address of that channel coincides with the broadcast address (IPSERV =
255.255.255.255), SSE232-LE will transmit to an UDP broadcast all the information received by
the serial. The serial will transmit whatever is received from the Ethernet side, no matter if the
information was received from a broadcast or from a specified IP address.

3.3.2 Server Channel with UDP Protocol
For a channel in Server Mode, you must only configure that channel’s Port. When the transport
protocol is UDP, the server channel will be “linked” to the first IP address plus Port that sends a
packet.
The Inactivity Timeout parameter must also be configured, and it will work similarly as in TCP
mode. It will terminate the link with a specified IP address (the first to have sent a packet) once
the predetermined time lapses, thus allowing another IP address to establish communication with
the UDP server channel.
