12 function module slots are provided on the back of each smart broadcasting center (host), and they can
configure 12 function modules. If a system needs to install more than 12 extend modules, then it is necessary to
connect a smart module extension box (M2800). A smart extension box can install 12 function modules. The
extension box is linked to the host or other extension boxes via network. See page 3 descriptions of the machine’s
back panel for the linking interface of the extension box.
