Devices with BUS CXN system
The CXN CAME system is a two-wire non-polarised communication BUS which allows you to connect up all compatible CAME
devices.
Connection to the BUS can be in a chain, star or mixed formation.
Once the system has been wired, and after having set the address on each device, the function of each accessory can be
confi gured on the control panel. This method allows you to confi gure the set-up immediately without having to do so later and
intervene directly on the accessories and system wiring.
