Notes on parallel operation with other USB devices
The use of other USB devices (for example a WebCam, bulk memory) on the PG/PC can impair
the performance of the communications processor.
Removing and inserting USB devices can cause functional disruptions on the USB interface. In
extreme cases, c
ommunication via the communications processor may even be aborted
making it necessary to restart the application.

First install the software before you connect the communications processor to the PG/PC,
see the section Software installation (Page 15).

Connecting to the PG/PC
Before you connect the communications processor to your PG/PC, note the following
information:
USB cable
To connect the communications processor, use only the supplied USB cable or another USB
cable suitable for industrial use.
USB connection to PG/PC
To achieve the guaranteed configuration limits with all protocols and at all bus transmission
speeds, you should use at least a USB 2.0 high-speed connector.
You should preferably use the USB connectors located at the back of the housing of your
PG/PC. The front USB connectors usually have a lower signal quality.
We recommend that you do not use any additional USB hubs.
