3.6 USB port
The ES583.1 must be connected to a USB 2.0 high-speed port (480 Mbit/s).
Since the module is supplied with power via the USB port, it must provide an
output current of 500 mA (USB 2.0 high power).
USB ports that can provide only a current of 100 mA are not being supported
(USB 2.0 low power). In case of insufficient current supply, the ES583.1 does
not boot and is not recognized as a USB device by the PC.
3.7 FlexRay interface (FLX1, FLX2)
The ES583.1 features a FlexRay interface with two channels (channel A and
channel B) that are routed to a 9-pin DSUB plug connector FLX1/FLX2. The
FlexRay channels A (FLX1) and B (FLX2) are completely independent channels
with separate connections.
The FlexRay interface is electrically isolated from the USB port. No electrical
decoupling exists between the FlexRay channels.
Operation of the module at USB 1.0 interfaces is not supported.
The module must be directly connected to the USB port of your PC. The use of
USB-cables extending the connection between the ES583.1 and the PC is not
allowed.
