DGN Interface
The DGN (Data Gathering Network, the name of the concentrator bus used in Windsor 500/700) to
XiB interface enables Vigil or Windsor 500 DGN concentrators to be connected to any XiB control
panel (PX or QX). The XiB control panel must support the number of circuits and concentrators on the
DGN bus (see table). The interface also allows DGN concentrator daughter board outputs to be
controlled by the XiB control panel. If daughter boards are fitted to the DGN concentrators then the XiB
control panel must be capable of supporting a corresponding number of output modules. Only one
interface can be used in a system.
The DGN supports anti-substitution and will report a concentrator tamper if a DGN concentrator is
substituted with a concentrator with the same address.
It is recommended that the DGN interface be mounted inside the control panel case using the supplied
adhesive pads. The XiB connector of the DGN interface can be connected to any of the panel XiB
busses and can share the bus with other XiB peripherals. Connect the bus cables from the
concentrators to the DGN bus connections. Note that the order of the DGN bus connections may not
be the same as the order of connections on the concentrators. (The DGN concentrator will have
terminals marked CLK/DATA or S0/S1.)
