System power and data communication

The one network power supply, single block configuration can be laid out as a closed perimeter, an
open perimeter, or in a linear configuration.
A multi-block configuration is used whenever there is a requirement to supply network power to
more than five processors via the sensor cables. One 48 VDC network power supply is used to
power each block of processors. The data connection between the blocks can be made between
any two processors, which maintain the loop configuration. For multi-block configurations, Senstar
recommends sensor cable connected blocks be limited to 5 processors per block. Overlapped
terminators ensure a closed perimeter, and a fiber optic data link provides optical isolation.
