Specifications and Documents Chapter: Connectors 3 Connectors This section describes all the connectors found on the CB2050. 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.
