11.2 Serial Interface
Two separate potential-free serial interfaces are provided to establish
IT connections.
These are occupied with the AEG protocol CBSER. Optionally,
various protocols can be selected for the second interface. These are
enabled upon purchase of a licence. A selection of the available
protocols can be obtained from your UPS supplier.
The interface is a separate PCB and is located on the outside of the
pivot plate next to the remote signalling unit.
For the implementation of special customer software as well as for
integration into special bus systems for visualisation using protocol
converters, a detailed protocol description is available from
AEG Power Supply Systems GmbH.
