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 configured on the control panel. This method
allows you to configure the set-up immediately without having to do so later and intervene directly on the accessories and system wiring.
The CXN BUS can support control devices, photocells, safety devices, beacons and gateways at the same time.
