operation is attempted. Improper use of this device in some applications may resu lt
in damage or injury. The user is urged to keep this book filed in a conv enien t location
for future reference.

These instructions may not cover all details or variations in equipment or cover
every possible situation to be met in connection with installation, operation or
maintenance. Should problems arise that are not cov ered suffici ently in the text, th e
purchaser is advised to contact Bris tol Babcock for further information.

EQUIPMENT APPLICATION WARNING

The customer should note that a failure of this instrument or system, for
whatever reason, may leave an operating process without protection. Depending
upon the application, this could result in possible damage to property or injury to
persons. It is suggested that the purchaser review the need for additional backup
equipment or provide alternate means of protection such as alarm devices, output
limiting, fail-safe valves, relief valves, emergenc y shutof fs, emergency switches, etc.
If additional information is required, the purchaser is advised to contact Bristol
Babcock.

RETURNED EQUIPMENT WARNING

When returning any equipment to Bristol Babcock for repairs or evaluation,
please note the following: The party sending such materials is responsible to en sure
that the materials returned to Bristol Babc ock are clean to safe lev els, as suc h levels
are defined and/or determined by applicable federal, state and/or local law regulations
or codes. Such party agrees to indemnify Bristol Babcock and save Bristol Babcock

ELECTRICAL GROUNDING

Metal enclosures and exposed metal parts of electrical instruments must be
grounded in accordance with OSHA rules and regulations pertaining to "Design
Safety Standards for Electrical Systems," 29 CFR, Part 1910, Subpart S, dated: April
16, 1981 (OSHA rulings are in agreement with the National Electrical Code).

The grounding requirement is also applicable to mechanical or pneumatic
instruments that include electrically-operated devices such as lights, switches, relay s,
alarms, or chart drives.

BBI ETHERNET MEDIA ACCESS UNIT (MAU)

GENERAL INTRODUCTION

The BBI Ethernet Media Access Unit (MAU) is an enclosed stand-alone device that
interfaces BBI DPC 3330/3335 products (equipped with an Ethernet CPU Assembly) to
IEEE 802.3 10BASE2 compatible networks.

The Media Access Unit (MAU) PCB is housed in a self contained box measuring 4.250”
(wide) by 4.625” (high). Two notches are provided on the unit’s base to accommodate
mounting to a panel or plate.

An external 9-30 Vdc Power Supply is required to power the MAU.

10BASE2 Ethernet, Network & Interface Requirements

By definition, an Ethernet 10BASE2 LAN runs at 10Mbits and can be a maximum length of
185 meters (607 feet) per segment. Network connection and interface requirements are
provided as follows:

• Maximum network length is 925 meters (3000 f eet)

• Interface to the network is accommodated by J1; an RG-58 A/U type BNC connector

• Minimum distance between T-connec tors is 0.5 meters (1.6 feet)

• Maximum number of connectors per segment is 30

• First and last device on each segment must be terminated on one side of their T-con-

nector with a 50 Ohm resistor

• T-connectors must be plugged directly into the MAU. No cable (stub) is allowed between
the T-connector and J1 of the MAU

COMPONENT IDENTIFICATION

The major components of the MAU are the Base, Cover, AUI Port Connector (P1), 10BASE2
Interface Connector (J1), Power Connector (TB1), Fuse (F1) and the Loop-back Jumper
(JP1).

Ethernet CPU Engine Attachment Unit Interface (AUI) Connector P1

P1 is a 15-pin male D-Type connector that provides an interface between an Ethernet CPU
Attachment Unit Interface (AUI) Port and the MAU. Table 1 provides the assignment and
definitions of the 15-p i n AUI Port Connector P1.

PIP-ENET-MAU Page - 1 Media Access Unit

An AUI/MAU transceiver cable can be a maximum length of 45 meters (150 feet). The use of
a cable manufactured for industrial environments is recommended.

Figure 1 provides the dimensions of the BBI MAU. Figure 2 shows the BBI MAU with cover
removed.

Figure 1 - BBI Media Access Unit Dimensions

PIP-ENET-MAU Page - 2 Media Access Unit

Figure 2 - BBI Media Acce ss Unit (Cover Removed)

MAU/Ethernet 10BASE2 Interface Connector J1

Connection to the thin-wire (10BASE2) Ethernet is made via the MAU’s BNC connector J1.
Tee connectors must be plugged directly into the MAU. No cable (stub) is allowed between
the Tee connector and J1 of the MAU. The first and last device on each segment must be
terminated on one side of their Tee connector with a 50-ohm resistor. Figure 3 shows the
MAU with a BNC T-connector installed on J1.

MAU Power Connector TB1

Connector TB1 provides an interface to an external power supply. Input power can range
from 9 to 30 Vdc. TB1-1 is designated +VDC Input, TB1-2 is designated -VDC Input and
TB1-3 is the Chassis Ground terminal. The external power supply must be capable of
delivering a continuous 1.8 Watts of power, e.g. (200 mA Max. @ 9Vdc), (100 mA Max. @
18Vdc), (75 mA Max. at +24Vdc ) & (60mA Max. @ 30Vdc).

MAU Fuse F1

Fuse F1 is rated at 0.25 Amps (see Figure 2).

PIP-ENET-MAU Page - 3 Media Access Unit

Figure 3 - MAU with BNC Tee Con nector installed on 10BASE2 Intf. Connector J1

Jumper JP1

SQE test (Heartbeat) Jumper JP1 is provided to test the integrity of the MAU/AUI interface
and the MAU circuitry. The MAU can generate a test signal on the Collision pair to indicate
to the DTE that it has recognized the end of a transmission and that the Collision pair is
operational. When JP1 is installed in position 1 to 2, the SQE test is disabled. The SQE test
is enabled when JP1 is installed in posit ion 2 to 3 (its normal posit ion).

ETHERNET DIAGNOSTICS

Bristol Babcock Diagnostics are available (see 33XX Diagnostics Manual - D4041) to test the
operation and integrity of the PCNET (Ethernet) Controller and Ethernet port hardware on
the Ethernet CPU Board. An Ethernet Diagnostic Menu can be entered from either the
Communication Diagnostic Menu or the Diagnostic Test Category Menu. The Loop-Back
Out AUI Port Poke Point must be pre sse d to test the hardware associated with the A UI P o rt
(including the MAU).

To configure the MAU for loop-back testing, the coaxial connections to the associated BNC
T-connector must be disconnected and two (2) 250 Ohm BNC terminators must be installed

PIP-ENET-MAU Page - 4 Media Access Unit

on the BNC T-connector. Once the MAU has been configured, the Loop-Back Out AUI Poke
Point can be activate d. If the Loop-Back Out AUI Poke Poin t is pressed while the MAU i s
attached to the Ethernet backbone, a Failure Status will be posted.

If either a “No Hardware Present” or “Error Information Returned” message is displayed,
ensure that the loop-back test requirements have been properly established. If test
requirements have been met and the cable associated with the AUI port and the Ethernet
CPU assembly is known to be good, the MAU should be replaced with a good unit.

In the case of a “Loop-Back Send Failed,” “Loop-Back Receive Failed” or Loop-Back
Compare Failed” message, check the cable in question and the MAU. If the cable associated
with the AUI port and the Ethernet CPU assembly is known to be good, the MAU should be
replaced with a good unit.
