Using the Coaxial Transceiver
The TRANSITION Networks Ethernet™ Coaxial Transceiver can be
attached to a PC or hub, using an IEEE 802.3 AUI drop cable.
If the Coaxial Transceiver fails, ask the following
question:
1. Is the power LED on the Coaxial Transceiver
illuminated?
NO
• Verify that AUI cables are IEEE 802.3
compliant.
• Verify that AUI cables are connected to
PC or hub.
• Verify that PC or hub connected to AUI
is powered ON. NOTE: Coaxial
Transceiver is powered by PC or hub.
• Contact Technical Support at (800) 2601312 or at (800) LAN-WANS.
YES
• Proceed to step 2.
2. Does Coaxial Transceiver provide access to
network?
NO
• Verify that coaxial network segment is
properly terminated at each end with 50
ohm terminator.
• Verify that coaxial network segment is
properly grounded at one end.
• Contact Technical Support at (800) 2601312 or at (800) LAN-WANS.
• If connecting the Coaxial Transceiver to a terminal device, set the SQE jumper to ON by
installing the SQE jumper as shown. NOTE: The SQE jumper is shipped in the default OFF
position.
• If connecting the Coaxial Transceiver to a hub or repeater, leave
the SQE jumper in the default OFF position as shipped.
• Attach the AMP tap assembly to the transceiver assembly by
removing the two screws (shown) from the transceiver assembly,
sliding the AMP tap assembly into the transceiver assembly, and
then reinstalling the two screws.
• Connect the AMP tap assembly to the network:
Model MC02:
The transceiver is attached to the thick coax via the AMP tap assembly,
part number 228752-1. An AMP installation tool kit, part number 228917-1 is required.
For complete installation instructions, read the instructions provided with the AMP coax
tap kit. Failure to install the coax tap properly may cause damage to the transceiver and
network.
Model MC03: The transceiver is connected to thick coax through the attached female N connectors on the AMP tap
assembly, part number 221914-1.
Model MC04:
The transceiver is connected to the thin coax through the attached BNC T connector on the AMP tap
assembly, part number 221918-1.
Model MC05:
The transceiver is connected through the attached straight BNC connector on the AMP tap assembly, part
number 222455-1. NOTE: A BNC "T" connector and terminator (not included) is required.
• AUI drop cable assembly cannot exceed 50 meters (165 feet).
• When installing thin or thick coax cable, remember to install a 50 ohm terminator at each end of the segment. Be sure
that one end of the segment is connected to earth ground.
Troubleshooting
Installation Notes
SQE ON: Set the SQE jumper to
ON when the Transceiver is
connected to a terminal device.
SQE OFF: Set the SQE jumper to
OFF when the Transceiver is
connected to a hub or repeater.
