8. Network Configuration using UDP
8.1 UDP Datagrams
The Device Server can also be configured or queried over the network using UDP datagrams. The Device Server has a UDP listener set for port 30718 (77FE Hex). Responses from the Device Server are returned to the source port of the UDP packet.
The first three bytes of the UDP data block should be set to zero. The fourth byte selects the function as described in the following table:
