Power supply via USB
The signotec Kronos Pen Display comes with a 3-in-1 cable featuring two USB ports and an HDMI port.
To supply the device with sufficient power, both USB-A plugs must be used. If the device is not supplied with sufficient power, it may fail to start, switch off sporadically, or fail to respond to pen or touch input.
Using an external power supply unit
Some systems do not provide the necessary 500 mA (USB 2.0) or 900 mA (USB 3.0/3.1) on each port as per USB specification. If the device does not receive sufficient power, it will not turn on or it may sporadically turn off. You will need to use an optional power supply unit to provide a reliable source of power.
This external power supply unit is connected to a power socket. On the other side, the red USB plug of the supplied connection cable is plugged in and connected to the device.
