Ethernet 10BaseT
Connector.
A RJ-45 connector that
interfaces the instrument with
a 10BaseT Twisted-Pair
Ethernet network. The
instrument automatically
selects the active 10Base2 or
10BaseT connector.

Ethernet 10Base2
Connector.
A BNC-type connector that
interfaces the instrument
with a 10Base2 coax
network. The instrument
automatically selects the
active 10Base2 or 10BaseT
connector.

Ethernet Indicators.
XMT (transmit) blinks
red for instrument
Ethernet transmissions;
RCV (receive) blinks
red for any Ethernet
activity on the network;
LK (link) lights amber
when the Ethernet
interface is active for
the Twisted-Pair
connection, and blinks
for a data collision for
the coaxial connection.
