All CUE Solution Units connect to an Ethernet network and support IEEE 802.1x - standard for port-based network access control.

Most units also support Power over Ethernet (PoE), other units are powered by a separate power supply.

The touchONE-overview unit provides an HDMI output for the display device and, if an interactive display is used, offers a touch sensor connection via a USB port. The functionality of this USB port is strictly limited to the operation of the touch sensor only, eliminating the risk of unauthorized use and compromising system security.

Occupancy sensors are typically connected via a digital input to the control unit. The software application running in the unit then mediates communication with the reservation panel using standard network secured protocols.
