Transition Networks E-CX-FRL-03 Installation Manual

About the Media Converter:

The Transition Networks, P/N E-CX-FRL-03, is an Ethernet Media Converter that
provides conversion from fiber optic cable (10BaseFL) to thin coax cable (10Base2).
The Media Converter has a BNC female coax connection and two Receive and Tran
ST type fiber optic connectors. The coax side will allow up to 24 coax devices to be
daisy chained together (610 feet max). The fiber optic ST connections will extend th
transmission distance up to 2000 meters (6,600 feet). An SMA type fiber connection
is also available, Transition Networks P/N E-CX-FRL-03(SMA).

Monitoring the Media Converter's LED's:
Main: Power - Lit green LED indicates normal operation.

Jabber - Flashing red LED indicates Jabber is active.

Coax Port: Receive (RX) - Flashing or lit green LED indicates packet(s) are being

received.

Collision - Flashing or lit red LED indicates a collision has occurred.

Fiber Port: Link - Lit green LED indicates the transceiver is receiving link

pulsed from a 10Base FL (or FOIRL) compliant device.

Receive (RX) - Flashing or lit green LED indicates one or more packets

have been received.

Collision - Flashing or lit red LED indicates line collisions.

Terminating the BNC connection:

The Media converter has an external thin coax 50 ohm, 25 ohm and NO terminatio
switch, which can be changed depending on the type of thin coax connection requi

Position (1) 50 ohms, is used when connecting the end of a coax segment directly to
BNC. NOTE: The other end of the coax segment must be terminated using a 50 ohm
terminator.

Position (2) requires a BNC "T" connector (NOT INCLUDED). This is used when
connecting the Media converter into the middle of a coax segment.

Position (3) is for 25 ohm termination and allows coax connection directly to the
workstation or DTE. A connection (cable) of less than 6 inches is required. A BNC m
to male adapter is recommended.

Power Supply Requirements:
