Multi-station operation and redundancy

Operating a dual-redundant primary device
For dual-redundant operation, each primary device must have an available
connection to both CUs. For dual-ported devices, such as the Sennet Network
Controller, there are two serial ports, which you can connect to two CUs.
However, many primary devices are single-ported and require a serial switching
device to connect them to two CUs. The serial switching device provides the
capability for single-ported devices to have switchable connections to two CUs.

illustrates a dual-
redundant Senstar 100 system with both dual-ported and single-ported primary
devices.
