Notice
Connecting a USB distributor (USB hub) to the HMI device's USB interface can cause a
restriction in the functionality of the connected USB devices and the HMI device.
Therefore, the simultaneous or alternating operation of USB devices connected via a USB
hub on the HMI device's USB interface is not approved.
This applies to USB hubs both with and without an internal power supply.
Notice
Use a standard mouse and keyboard with a "USA/International" keyboard layout.
Commercially available USB devices do not normally meet the higher industrial demands
relating to interference resistance and can have negative effects on the HMI device.
The power consumption must not exceed 500 mA with the USB units connected.
