take advantage of internal termination, the slide switch should be in the "DOWN" (or right-side)
position. In this configuration, the 10BASE2 segment is directly attached to the BNC port where
it is internally terminated. When the switch is in the "UP" (or left-side) position, the BNC port
requires a "tee" connector (not
supplied) and a 50 ohm terminator
for proper termination. Certain
applications may require a "tee"
connector, used as a tap, to allow
the 10BASE2 coax segment to
continue on past the RPM-BNC
connection.
Magnum RPM-BNC
The RPM-BNC module includes one partition (PART) and one receive (RX) LED,
which are visible from the front. The PART LED flashes AMBER to indicate that the segment
has been automatically partitioned. As soon as normal transmission resumes, the segment will
be automatically re-established. The RX LED illuminates GREEN intermittently to indicate data
is being received.
Important Note: for the RPM-BNC Termination Switch -
DOWN (or right): Internally Terminated
UP (or left): Requires "T" Connector.
(To recall the right BNC switch position, remember "tee up" . . as in golf ! )
2.3.2 RPM-AUI
This module is equipped with a 15 pin female AUI connector and a slide-lock, and
performs full IEEE 802.3 repeater functionality. It is used to provide connectivity with a
10BASE5 (ThickNet) backbone or to
any AUI segments. A transceiver is
required when connecting to a
ThickNet segment and the RPM-AUI
supports this convention. The RPM-
AUI is also a "universal" Ethernet
media interface as it may be used with
a variety of different mini-transceivers
