Certification Notice for
Equipment Used in Canada
The Canadian Department of Communications label identifies certified equipment. This certification means that the equipment meets certain telecommunications-network protective, operation, and safety requirements. The Department does not guarantee the equipment will operate to the user’s satisfaction.
Before installing this equipment, users should ensure that it is permissible to be connected to the facilities of the local telecommunications company. The equipment must also be installed using an acceptable method of connection. In some cases, the company’s inside wiring associated with a single-line individual service may be extended by means of a certified connector assembly (extension cord). The customer should be aware that compliance with the above conditions may not prevent degradation of service in some situations.
Repairs to certified equipment should be made by an authorized Canadian maintenance facility—in this case, your supplier. Any repairs or alterations made by the user to this equipment, or equipment malfunctions, may give the telecommunications company cause to request the user to disconnect the equipment.
Users should ensure for their own protection that the electrical ground connections of the power utility, telephone lines, and internal metallic water pipe system, if present, are connected together. This precaution may be particularly important in rural areas.
CAUTION:
Users should not attempt to make such connections themselves, but should contact the appropriate electric inspection authority, or electrician, as appropriate.
The LOAD NUMBER (LN) assigned to each terminal device denotes the percentage of the total load to be connected to a telephone loop which is used by the device, to prevent overloading. The termination on a loop may consist of any combination of devices, subject only to the requirement that the total of the load numbers of all the devices does not exceed 100.

2.0 INTRODUCTION
2.1 Inspecting the Package and Product
Examine the shipping container for obvious damage prior to installing this product; notify the carrier of any damage that you believe occurred during shipment or delivery. Inspect the contents of this package for any signs of damage and ensure that the items listed below are included.
This package should contain:
1 Coax Transceiver (and, optionally, one tap if ordered)
1 User Guide
1 Product Registration Card
Remove the Black Box Coax Transceiver from the shipping container. Be sure to keep the shipping container should you need to ship the unit at a later date. In the event there are items missing or damaged contact your supplier. If you need to return the unit use the original shipping container. Refer to Section 5, Troubleshooting, for specific return procedures.
2.2 Product Description
Black Box Coax Ethernet Transceivers offer a simple, cost-effective method for direct connection of network devices to the Ethernet backbone. Coax Transceivers comply with Ethernet V1.0/2.0 as well as IEEE 802.3 specifications to support ThickNet (10BASE5) and ThinNet (10BASE2) backbones. Using a single network tap (BNC-T, or Cable Piercing), the Coax Transceivers allow a device to be easily added to the network.
Black Box Coax Transceivers provide a convenient and cost effective way of increasing the number of available AUI ports on an Ethernet network from a single backbone tap. Each Coax Transceiver is made with a metal enclosure, ensuring reliability and durability in addition to meeting FCC emission standards.
Compact and durable, Coax Transceivers are suitable for installation above drop ceilings adjacent to air supply ducts or plenums. There is no necessity to wall mount or install these units in a rack.
Each unit also features a set of LEDs to simplify installation and diagnostic capabilities. All LEDs are positioned on the front of the unit for ease of readability. In addition to LEDs, Coax Transceivers offer the ability to configure SQE (through jumper settings) either ON or OFF depending on network requirements. (See Section 4.4, SQE Test)
Since Black Box Coax Transceivers derive power from the network and do not require a separate AC power supply unit, the costs and installation issues associated with power supplies are eliminated.
The family of Ethernet Coax Transceivers is represented by 3 different configurations among three models. Depending on application requirements, Black Box Coax Transceivers are optionally configured at the time of order in one of three ways, with no tap, with a BNC-T connector, or with a Cable Piercing ThickNet tap connector.
The Black Box Coax Transceiver family includes these three models:
As with all coax Transceivers, Black Box Coax Transceivers are configured with one of three tap options: cable piercing, BNC-T, no tap
LE003A-R2 (cable piercing)
LE004A-R2 (BNC-T)
LE008A-R2 (No Tap)
2.2.1 LE003A-R2 (Cable Piercing)
The Black Box LE003A-R2 Coax Transceiver is equipped with a single AUI station port and a cable piercing tap. The cable pierce is used mainly for 10Base5 Thick Coax cable as a media to transmit and receive the data, which supports 500 meters length segment max.
The 10Mb Thick Coax allows 5 segments max. with 2.5 meter spacing and 50 ohm terminators on each segment.
Black Box LE003A-R2 includes six LEDs on the front to indicate power (PWR), SQE, transmit (TX), receive (RX), collision (COL), and Jabber (JAB). Additionally, the LE003A-R2 Ethernet Coax Transceiver is designed with an SQE jumper inside, located as shown in Section 4.4, Figure 4.4. The SQE jumper allows this unit to be installed in applications where SQE Testing may or may not be required.
2.2.2 LE004A-R2 ( BNC-T)
The Black Box LE004A-R2 Coax Transceiver is equipped with a single AUI station port and a 10Base2 BNC-T connector port to connect to any BNC segment. The 10Mb BNC ThinNet allows 185 meter segment lengths with 5 segments max. The 10Base2 ThinNet media has a capability of 30 physical taps or attachments per segment with 0.5 meter spacing between the taps. A 50 ohm terminator is needed on each end.
The Black Box LE004A-R2 includes six LEDs to indicate power (PWR), SQE, transmit (TX), receive (RX), collision (COL) and Jabber (JAB). Additionally, the LE004A-R2 is designed with an SQE jumper inside, located as shown in Section 4.4, Figure 4.4.
The SQE jumper allows this unit to be installed in applications where SQE Tests may or may not be required.
