For a correct and complete connection of the unit, proceed as follows:

- Connect the unit to a **data network** equipped with **PoE** technology.
- If the data network does not have PoE technology, use an external **PoE Adapter**, e.g. [https://cue.atlassian.net/wiki/spaces/PRODUCTS/pages/490012788](https://cue.atlassian.net/wiki/spaces/PRODUCTS/pages/490012788).

> 📝 **PoE requirements**
> 📝 
> 📝 - PoE IEEE **802.3af / Class 0** for one USB usage, max. 0.5 A output (USB2 mode)
> 📝 - PoE+ IEEE **802.3at / Class 4** for both USBs usage, max. 0.9 A output each (USB3 mode)

- Connect a large screen display with a resolution of Full HD (1920 x 1080 pixels) or 4K (3840 x 2160 pixels) using an **HDMI** video cable.
- If the display is equipped with a touch sensor and you will use interactive functions in your application, connect the output of the touch sensor to the unit using a **USB **cable.
- If the display is equipped with an RS-232 or RS-485 serial port, it can be controlled from the unit using [https://cue.atlassian.net/wiki/spaces/PRODUCTS/pages/297926658](https://cue.atlassian.net/wiki/spaces/PRODUCTS/pages/297926658) serial control port. It is typically possible to turn the display on and off, set the correct input, adjust the volume, etc.
