Protocol Specific Functionality and Parameter Settings
While the standard ID_read and anti-collision searches are supported by practically all offered protocols, hence
no protocol-specific information is required to issue and RQL search. More specific commands, such as
data_read and data_write require protocol specific information when formatting the query and interpreting the
results. The tables below provide that information.
