IRC–REAL TIME COMMUNICATIONS
The information is transmitted real time, for example if a PLU is created on one terminal the information is
automatically transmitted to all machines within the network. The real time principal is also applied to check
details and employee interrupt sale data. This information is held in one terminal and can be updated and
accessed on any terminal within the network
The SER 7000 uses 10 base 'T' network, which incorporates an ETHERNET HUB communications method,
this means if more than two terminals are to be connected together a hub is used, providing effective data
transfer such as automatic file recovery.
