They are optional accessories to RipEX, for more details see Section 5.3, "Connecting RipEX to a
programming PC". The adapters are used for service access to RipEX's web configuration interface.
The USB interface can also be used for an external flash disc connection, which has been specifically
designed to simplify complex maintenance tasks, so that these tasks can be performed by unqualified
personnel in the field by simple plugging-in an USB stick and waiting until a LED flashes.

connected device, for instance a telephone. The USB connector should not be used as permanent
source of power supply.
