Transition Networks E-TBT-FRL-01 User Manual

The TRANSITION Networks Ethernet™ 10BaseFL/10BaseT Adapter (media converter), E-TBT-FRL-01, connects fiber optic cable (10BaseFL) to twisted pair (10BaseT).

The 10BaseFL/10BaseT Adapter provides an RJ-45 twisted pair connector and a set of Receive and Transmit ST fiber optic connectors. The twisted pair connection allows a 10BaseT device to be located at a distance of up to 100 meters (185 feet). The fiber optic ST connections allows a device to be located at a distance of up to 2000 meters (6,600 feet). NOTE: A media converter with an SMA type fiber connection, E-TBTFRL-01(SMA), also is available.

Status LEDs provide the following information:

Link Illuminated green LED indicates the unit is receiving link pulses from a

compliant device.

Receive: Flashing or illuminated green LED indicates packet(s) are being received. Collision: Flashing or illuminated red LED indicates collisions are occurring.

Power: Illuminated green LED indicates normal operation. Jabber: Illuminated red LED indicates the unit is disabled.

Straight Through/Crossover Cable Requirements and Pin Specifications

The two active pairs in a 10BaseT network are pins 1 & 2 and pins 3 & 6. Use only dedicated wire pairs (such as blue/white & white/blue, orange/white & white/orange) for the active pins.

Cable connections between a hub and the media converter must be configured as straight through. Cable connections between the media converter and a terminal, transceiver or NIC must be configured as crossover.

1. Is the power LED on the media converter illuminated?

• Is the power adapter the proper type of voltage and cycle frequency for your AC outlet? NOTE: Refer to the “Power Supply Requirements” on the back page.

• Is the power adapter properly installed in the media converter and in the outlet?

• Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.

YES

• Proceed to step 2.

2. Is the 10BaseT Link LED illuminated?

• Check UTP cables for proper connection and pin assignment. (See below.)

• Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.

YES

• Proceed to step 3.

2. Is the fiber Link LED illuminated?

• Check fiber cables for proper connection.

• Verify that TX and RX cables on media converter are connected to RX and TX ports,

respectively, on the other 10BaseFL device.

• Contact Technical Support at (800) 260-1312 or at (800) LAN-WANS.

YES

• Be certain that the 10BaseT cable is

configured correctly (straight through or crossover) for site installation.

• Verify that both the fiber products to be connected are 10BaseFL or FOIRL compliant. (The fiber port on the TRANSITION Networks E-TBT-FRL-01 conforms to 10BaseFL or FOIRL but NOT to 10BaseFB or FDDI.)

• 62.5/125 micron duplex fiber cable is recommended.

• The maximum dBm loss for the fiber cable should not exceed 13 dBm.

• Connect the power supply cable to the media converter BEFORE connecting to the outlet.

• This unit must be installed with the PSU provided. (Output 9 VDC regulated, 500 mA).

• Connecting more than two media converters in series is not recommended.
