AUTION
For most interfaces, the cables must meet certain requirements. For instance, USB 2.0 requires twisted and
shielded cables to reliably maintain full speed data rates. Restrictions on maximum cable length are also in
place for many high speed interfaces and for power supply. Please refer to the respective specifications and
use suitable cables at all times.
