Table 1
— Cabling Considerations
* If using shielded cable, connect to chassis at only one point.
NOTE: Wire size may be dictated by electrical codes for the area where the
equipment is being installed. Consult local regulations.
Observe in Table 1 that 10BASE-T segments can successfully use Category 3, 4 or
5 cable
— but 100BASE-TX segments must use Category 5 cable. Category 5e
cable is highly recommended as the minimum for new installations.
The Ethernet port of the BASC20 employs Auto-MDIX technology so that either
straight-through or crossover cables can be used to connect to the network.
