This section describes the data transferred using the [[NWM_Services|UDS]] service. All data is stored as big-endian.
−UDS [[NWMUDS:Bind|data_channel]] 0x1 is used for spectator data, while all non-spectator data uses data_channel 0x2. The spectator data is received by connecting to the network as a spectator then receiving data-frames, this is handled when scanning for DLP networks. This spectator-data contains the DLP icon and the sysupdate titlelist.
