I-87211W User Manual V2.5, Oct. 2010

2 DCON Protocol

All  communication  with  I-87K  modules  consists  of  commands
generated  by  the  host  and  responses  transmitted  by  the  I-87K
modules.  Each  module  has  a  unique  ID  number  that  is  used  for
addressing purposes and is stored in nonvolatile memory. The ID is
00  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
are the commands #** (Section 2.2) and ~** (Section 2.27), which
are sent to all modules, but in both of these cases, the modules do
not reply to the command.
