IP address ('' for broadcast)

Specify the IP address or host name to which the block sends the message. To broadcast the UDP message, retain the default value, ''.

Local IP port

Specify the IP port number from which the block sends the message, from 1 – 65535.

If the receiving address expects messages from a particular port number, enter that number.

The default value, -1, sets the port number to 65535.
