FCC AND IC STATEMENTS
FEDERAL COMMUNICATIONS COMMISSION
AND
INDUSTRY CANADA
RADIO FREQUENCY INTERFERENCE STATEMENTS
This equipment generates, uses, and can radiate radio-
frequency 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

8
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.

9
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).

11
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.
CHAPTER 3: Installation

12
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.

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.
CHAPTER 4: Troubleshooting

14
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.

Connector Pinout
Pin Symbol Name/Function
1 CI-S Control-In Shield: The shield for the
CI twisted pair in the AUI cable.
2 CI-A Control-In Circuit A: The positive
signal for the CI circuit. With CI-B,
CI-A is an output current driver pair
to the CI circuit. This output pair is
activated when a collision is detected
on the network, either during self-test
(heartbeat) as the SQE test
sequence or after the watchdog timer
has expired to indicate that the
transmitter is disabled.

Pin Symbol Name/Function
3 DO-A Data-Out Circuit A: The positive
signal for the DO circuit. With DO-B,
DO-A is a differential receiver input
pair from the DO circuit. This input
pair receives 10-Mbps Manchester-
encoded data from the AUI
transceiver cable, which is driven by
the DTE (terminal or computer).
4 DI-S Data-In Shield: The shield for the DI
twisted pair in the AUI cable.
5 DI-A Data-In Circuit A: The positive signal
for the DI circuit. With DI-B, DI-A is
an output current driver pair to the DI
circuit. This output pair drives the
AUI transceiver cable with 10-Mbps
Manchester-encoded data received
from the coaxial cable wire of the
network.
