2. DCON Protocol
All communication with I-7000 modules consists of
commands generated by the host and responses
transmitted by the I-7000 modules. Each module has a
unique ID number that is used for addressing purposes and
is stored in non-volatile memory. The ID is 01 by default
and can be changed using a user command. All
commands to the modules contain the ID address,
meaning that only the addressed module will respond.
The only exception to this is command ~** (Section 2.34),
which are sent to all modules, but the modules do not
reply to the command.
