Table 1 — Cabling Considerations
NOTE: If using shielded cable, connect to chassis at only one point. 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 — however, 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 BASR employs Auto-MDIX technology so that either
straight-through or crossover cables can be used to connect to the network.
