USER’S GUIDE

FCC Regulations:

Note: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference in which case the user will be required to correct the interference at his own cost.

NOTE: This digital apparatus does not exceed the Class A limits for radio noise for digital apparatus set out

on the radio interference regulations of the Canadian Department of Communications. NOTE: This equipment has been tested and found to comply with VDE Class B requirements. For selling in the Federal Republic of Germany:

Ethernet™ Coaxial Transceiver

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?

• 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?

• 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.
