Cable Type
Windsor has two 4 wire buses, one for the user interfaces and one for the concentrators. The
recommended cable type is 7 strand/0.2mm
2
diameter un-screened cable which has a
resistance of 90 ohms/km and a core to core capacitance of 100nF/km. The screened cable
referred to in this manual has the same resistance as un-screened cable but has a higher
capacitance of 250nF/km between any core and the screen. If screened cable is used it
should be terminated in the Windsor control panel and connected to earth. Refer to the
section on user interfaces and concentrators for details of the maximum length of cable on
each bus.
