1.4 852 Protocol Packets

This entry is part 11 of 11 in the series Lon over IP (709.1/852)

Two types of packets are used by the 852 protocol. These are CN Data packets and 852 Channel Management packets. Both packets use a common packet header. The payload of a CN Data packet is the 709.1 LPDU (Link Layer Protocol Data Unit) (See diagram below). The payload of a Channel Management packet is configuration information for the 852 devices. There is some important terminology needed to understand how to deploy an 852 based system which we cover in the next section.
