Important Note
Maximum cable length allowed for USB connection is 3 m. If longer cables are used,
special overvoltage and filtering elements have to be installed to comply with the
requirements of EMI/RFI "CE"-certification. Only use high quality industrial USB
devices with sufficient EMI compatibility.
Use shielded cables for maximum EMI protection.
Drawing excessively power might disturb operation.
