XiB Busses
The 3A Smart Concentrator has 2 XiB connectors, XiB in and XiB out. The XiB in connector must be
used to connect the XiB bus from the panel. All 4 wires may be connected but the XiB in + terminal is
not connected to the XiB out + terminal. The XiB out connector is used to connect all XiB peripherals
that are to be powered from the 3A Smart Concentrator. The XiB out bus is electrically isolated from
the XiB in bus and peripherals can be connected on the XiB out bus up to 1.7km from the 3A Smart
concentrator (at 9k6 baud).
