16-PORT TYPE 3 MAU
RJ-11 male connectors may be used instead of RJ-45 male connectors on the
twisted-pair cables used in the network. Both types will work in the female
connectors on the MAUs. Whether RJ-45 or RJ-11 male connectors are used,
the transmit and receive pins are always the four center pins in the connector,
as shown in
Figure 1-1
.
IMPORTANT NOTE:
The cable used with your MAUs must have at least two twisted pairs of
wire for data, no matter what cable type is used. This means a minimum
of four separate wires, whether or not you will use all four. The cable
must be wired straight-through, as shown in Figure 1-2. Do not connect
transmit and receive wires in the same twisted pair of wires.
