12.9 USB 2.0 and USB 3.0 Interfaces
12.9.1 ES820.1 Drive Recorder
The Drive Recorder ES820.1 provides two USB 2.0 interfaces and two USB 3.0 inter-
faces.
These interfaces only support USB devices that feature software/drivers that are
compatible with Windows. The basic functions of the USB devices connected to
the USB interfaces can be used immediately without the prior installation of a spe
-
cific driver. Manufacturer-specific extensions that require additional software or a
dedicated driver must be installed by the user.
12.9.2 ES830.1 Rapid Prototyping Module
The Rapid Prototyping Module ES830.1 provides two USB 2.0 interfaces and two
USB 3.0 interfaces.
These interfaces only support USB devices that feature software/drivers that are
compatible with the QNX operating system. The basic functions of the USB
devices connected to the USB interfaces can be used immediately without the
prior installation of a specific driver by ETAS.
12.9.3 "Wake-Up" Function
The USB interfaces support the "Wake-Up" function. When the "Wake-Up" func-
tion is activated, the power supply to the USB interfaces remains switched on,
even in the "Standby" operating state.
NOTE
Please ensure that the functionality of the USB interfaces on the ES830.1 module
is enabled for operation later.
NOTE
Support for the "Wake-Up" function at the USB interfaces will be enabled for
operation at a later point in time.
NOTE
Connected devices that support the "Wake-Up" function can trigger a change in
operating state from "Standby" to "On" with the ES820.1 module. Therefore, only
activate the "Wake-Up" function if the function is to be used.
NOTE
If the "Wake-Up" function is activated for one or more USB interfaces, the cur-
rent consumption increases in the "Standby" operating state. It is possible to
discharge the vehicle battery prematurely.
