10BASE2 coax connector. This

RPM performs full IEEE 802.3

repeater functionality and is used

for 10BASE2 ThinNet Magnum RPM-BNC

(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 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 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.

RPM-TP (Twisted Pair)

The Magnum RPM-TP card supports Ethernet twisted pair segments of any

standard length. It is equipped with a single RJ-45 connector. The RJ-45 connector is
