4.2.1 RPM-BNC
The Magnum RPM-BNC repeater module is equipped with a standard
10BASE2 coax connector. This RPM performs full IEEE 802.3 repeater functionality
and is used for 10BASE2 ThinNet (commonly referred to as BNC) connections.
The RPM-BNC module is designed with a special switch-selectable internal
termination function that eliminates the need for a "tee" connector and a 50 ohm
terminator. To 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
Magnum RPM-BNC
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.
The RPM-BNC module includes one partition (PART) and one receive (RX)
LED, which are visible beside the connector. The PART LED illuminates AMBER to
indicate that the segment
has been automatically
partitioned. As soon as
normal reception 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) = "T" Connector required.
