The interface is located under a screw cap with IP65 protection class. This is fastened by an interior retaining
wire and therefore cannot be lost even after unscrewing. In order to gain access to the interface, unscrew the
cap and let it dangle on the retaining wire.
The USB interface is used to connect peripheral devices with a USB connection. It is a USB-A socket. USB
specification 2.0 is supported.
