FCC AND IC STATEMENTS
FEDERAL COMMUNICATIONS COMMISSION
AND
INDUSTRY CANADA
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radiofrequency energy, and if not installed and used properly, that is, in strict accordance with the manufacturer’s instructions, may cause interference to radio communication. It has been tested and found to comply with the limits for a Class A computing device in accordance with the specifications in
Subpart B of Part 15 of FCC rules, which are designed to provide reasonable protection against such interference when the equipment is operated in a commercial environment.
Operation of this equipment in a residential area is likely to cause interference, in which case the user at his own expense will be required to take whatever measures may be necessary to correct the interference.
Changes or modifications not expressly approved by the party responsible for compliance could void the user’s authority to operate the equipment.
This digital apparatus does not exceed the Class A limits for radio noise emission from digital apparatus set out in the Radio Interference
Regulation of Industry Canada.

CHAPTER 2: Introduction
2. Introduction
2.1 Description
The AUI to BNC Transceiver lets you connect an Ethernet device (such as a LAN card installed in a PC, or a bridge, router, hub, or repeater) to thin Ethernet coaxial cable. It connects either directly to the AUI port on the Ethernet device or via a standard AUI cable. The transceiver complies with IEEE 802.3 transceiver specifications.
2.2 What the Package Includes
Your package should include the following items:
• (1) AUI to BNC Transceiver
7
AUI TO BNC TRANSCEIVER
• (1) BNC T-connector
• This users’ manual
If anything is missing or damaged, please contact Black Box at 724-746-5500.
2.3 Features
• Provides a complete AUI to thin
Ethernet (10BASE2) interface, including transmit, receive, collision, and jabber functions, and SQE
(signal quality error) test.
• Supports message traffic at a data rate of 10 Mbps.
• Extends a coaxial cable segment up to 606.8 feet (185 m) without a repeater.
8
CHAPTER 2: Introduction
• Supports system configurations using the CSMA/CD access mechanism defined in the IEEE Local Area
Network specifications.

3. Installation
3.1 Disabling SQE Test
When the transceiver is attached to a LAN card, bridge, or router, the SQE switch
(located on the bottom of the transceiver) should be ON.
When the transceiver is attached to a hub or repeater, the SQE switch should be
OFF.
NOTE
The transceiver is shipped from the factory with the SQE (heartbeat) test enabled (ON).
10
CHAPTER 3: Installation
3.2 Installing the Transceiver
1. Turn the power to the network device off.
2. Connect a BNC T-connector to the transceiver’s BNC female connector, then connect thin coax cable to the
T-connector. If only one end of the
T-connector is connected, install a
50-ohm BNC terminator on the other end.
3. Use a standard AUI cable (50 ft.
[15.2 m] long) to connect an
Ethernet device to the transceiver’s
DB15 AUI connector, or directly mount the transceiver to a DTE.
4. Turn the power to the network device back on. Verify that the Power
LED on the transceiver is on.
11
AUI TO BNC TRANSCEIVER
Once the transceiver is installed, it operates automatically in half-duplex mode. When the SQE LED lights, a collision is detected on the AUI port.

CHAPTER 4: Troubleshooting
4. Troubleshooting
4.1 Calling Black Box
If you determine that your AUI to BNC
Transceiver is malfunctioning, do not attempt to alter or repair the unit. It contains no user-serviceable parts. Contact
Black Box at 724-746-5500.
Before you do, make a record of the history of the problem. We will be able to provide more efficient and accurate assistance if you have a complete description, including:
• the nature and duration of the problem.
• when the problem occurs.
13
AUI TO BNC TRANSCEIVER
• the components involved in the problem.
• any particular application that, when used, appears to create the problem or make it worse.
4.2 Shipping and Packaging
If you need to transport or ship your AUI to BNC Transceiver:
• Package it carefully. We recommend that you use the original container.
• If you are shipping the transceiver for repair, make sure you include everything that came in the original package. Before you ship, contact
Black Box to get a Return
Authorization (RA) number.
