4.5 TB14s, BNC Internal Termination Switch
An internal termination switch (∝ - 50Ω) is provided
on the TB14s Model. The BNC port is specially
equipped with an internal termination switch that
eliminates the need to use a "tee" connector when the
BNC cable is ending at the TB14. When the switch is
in the “50Ω” position, the connection is internally
terminated. When switched to the “∝” position,
external termination (using a “tee” connector, not
supplied) is required. Some applications may require a "tee" connector, used as a tap, to
allow the 10BASE2 coax segment to continue on past the TB14 and TB14H port
connection.
