APCD-LM011-A 3
1.2 CAP
The CAP serves a routing function for the LMS3200 data communication by providing a
collection point for the EUM data, and translating this data to a single data stream. It also acts
as a distribution point for data received from the NAP by translating the data from a single data
stream into multiple radio signals. This information then transmits to the appropriate EUMs.
