Installation
BNC Port
❏ A BNC female connector allows the connection of an RG-58 thin-cable net-
work to the hub. A switch selectable 50-ohm internal terminator is built into
the BNC port.
IN/EXT Terminator Switch
❏ The switch labeled INT/EXT is used to select either an external or an internal
terminator for the BNC port.
❏ When a BNC port of the hub is placed at the furthest end of a segment, you
may choose to use an internal terminator for the BNC port by turning its
switch to the INT position. Next, connect the port to the thin cable directly
without attaching a T-connector and a terminator.
❏ When a BNC port is connected to any port of a segment apart from the seg-
ment ends, the terminator switch should be placed to the EXT position to dis-
able the internal terminator and a T-connector will be used.
LED Indicators
❏ The PWR LED lights up when the hub is powered on.
❏ The LINK LED monitors the link status.
❏ The Tx/Rx LED lights up when the hub transmits or receives data from any
port.
❏ The COL LED lights up when collisions are detected on the network.
16 RJ-45 Ports
❏ 16 ports are RJ-45 modular jacks for the twisted-pair cable to connect stations
to the hub. The sixteenth RJ-45 can be used to connect to an adjacent Ether-
net hub.
OFF/ON Uplink Switch
❏ The switch labeled Uplink next to the sixteenth RJ-45 port is used to control
the pin configuration of the sixteenth RJ-45 port. To connect the sixteenth
RJ-45 port to a station, slide the switch to the OFF position. To connect to an
adjacent Ethernet hub, slide the switch to the ON position.
