J/E-CX-TBT-01

Stand-Alone Media Converter

• Coax to Twisted-Pair

• 10Base-2 to 10Base-T

The Transition Networks J/E-CX-TBT-01 Ethernet media converter connects 10Base-T shielded or unshielded twisted-pair copper cable to 10Base-2 coaxial copper cable.

The J/E-CX-TBT-01 supports up to 24 devices daisy-chained on one coax segment per twisted-pair segment.

Installation

Install the Coax Cable

1.Locate or build 10Base-2 compliant coax cable with female, BNC connectors installed at both ends.

2.Connect the BNC cable connector at one end of the cable to the BNC port on the media converter.

3.Connect the BNC cable connector at the other end of the cable to the BNC port on the 10Base-2 compliant device.

CAUTION: Ensure that the 10Base-2 coax cables are terminated properly at both ends. In a coax thinnet installation, the first and last device in a daisy-chain must be terminated using a 50 Ω terminator. Also, ensure that the 10Base-2 segment is grounded to earth ground at a single point. Failure to observe this caution will cause data transfer to fail.

Install the 10Base-T Cable

CAUTION: Connections between the J/E-CX-TBT-01 and a hub, switch, or router require crossover configuration cable. Connections between the J/E-CX-TBT-01 and a terminal, transceiver, or NIC require straight-through configuration cable. (See page 4.) Failure to observe this caution will cause data transfer to fail.

1.Locate or build 10Base-T compliant copper cables with male, RJ-45 connectors installed at both ends.

2.Connect the RJ-45 connector at one end of the cable to the RJ-45 port on the media converter.

3.Connect the RJ-45 connector at the other end of the cable to the RJ-45 port on the 10Base-T compliant device.

Operation

Power the Media Converter

NOTE: The external power supply provided with this product is UL listed by the power supply’s manufacturer.

1.Connect the barrel connector on the power adapter to the media converter’s power port (located on the back of the media converter).

2.Connect the power adapter plug to AC power.

3.Verify that the media converter is powered by observing the illuminated LED power indicator light.

Status LEDs

Use the status LEDs to monitor media converter operation in the network.
