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.

J/E-CX-TBT-01
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.
Connect the coax cable
to the first media
converter as shown.
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.
Connect the coax cable
to the 10Base-2 compliant
device as shown
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.
PWR On = Connection to external AC power.
BNC ACT Flashing = 10Base-2 data traffic.
TX LNK/ACT On = 10Base-T link connection.
Flashing = 10Base-T data traffic.
