To connect the Processing Unit network, use twisted pair (TP) cable with RJ-45
connectors. To comply with the IEC 60945 standard shielded (screened) cable has to be
used. Recommended cable type is CAT-5e. Category 5e cable is an enhanced version of
Category 5 that adheres to more stringent standards. It is capable of transmitting data at
speeds of up to 1000 Mbps (1 Gigabit per second). The maximum length of the cable
that can be used is 100 metres (328 ft).
