25�5 Inventory taking per UDP/8513
UDP port 8513 allows you to open an info-structure with de-
vice-specific information from the Com-Server. After receipt of
a network packet with any contents directed to this port, the
Com-Server replies with the info-packet. By configuring the
request packet as a broadcast, you can inventory all the W&T
devices located in the local network.

25�5�1 The infopaket
Each infopacket consists of 3-6 data structures. BOX_VERSION
contains information on the respective model of the Com-Ser-
ver and its firmware status. The structure
BOX_DESCRIPT pro-
vides the network-relevant data such as MAC- and IP-address.
The 3.-6. structure
PORT_DESCRIPT provides information
about the configured mode and the current connection status
of the individual ports. The total length of the InfoPacket is
calculated as follows: 1
0 + 22 + (port_no x 10) bytes.
