Many products have large, easy-to-read legends to

allow for the easy configuring of the product. This

installation manual contains detailed instructions.

Most included software has automatic installation

programs to place the software correctly onto your

computer. However, as all computers are configured

differently, you may be required to perform some basic DOS or Windows

tasks. If you are not familiar with basic DOS commands such as DIR,

CD, or EDIT, you should check your DOS manual, or seek assistance

from you local computer dealer to install the product.

We use many world-class quality assurance programs to ensure the

product you purchased is of the highest caliber. Sometimes, however, a

component may be missing from the box, or is damaged or corrupt in

some way. If this happens, immediately return the entire package to your

place of purchase so you may exchange it for a new one. Your dealer

should be able to provide you with an exchange far more quickly than by

contacting us directly. If for some reason you are unable to return the

product directly to its place of purchase, refer to the “Servicing Your

automatic recovery due to wiring errors.

Functional DescriptionFunctional Description

Functional Description

The BocaNET-24 is an implementation of an IEEE 802.3/

Ethernet repeater or hub. It provides 24 10BASE-T ports, one

10BASE2 port, one AUI port, and one expansion port in a

single hub. The BocaNET-24 complies with the full set of

repeater basic functions as defined in section 9 of ISO 8802.3

(ANSI/IEEE 802.3). These functions are defined below:

Repeater FunctionRepeater Function

Repeater Function

If any single network port senses the start of a valid packet

on its receive lines, then the BocaNET-24 will re-transmit the

received data to all other enabled network ports.

When re-transmitting a packet, the BocaNET-24 ensures that

the outgoing packet complies with the 802.3 specification in

terms of preamble structure, voltage amplitude, and timing

characteristics.

The BocaNET-24 implements a built-in jabber protection

scheme to ensure that the network is not disabled due to the

transmission of excessively long data packets.

Collision HandlingCollision Handling

Collision Handling

The BocaNET-24 will detect and respond to collision

conditions as specified in 802.3. It will also protect the

network from excessive collisions by “partitioning” the

offending port from the rest of the network. Once a port is

partitioned, the data received from that port will not be

repeated. However, any other data on the network will be re-

transmitted on that port. If the collisions that cause the

partitioning cease, the port will be re-connected to the rest of

the network.

The status of the partitioning scheme can be checked at any

time by observing the bi-color LINK/PRT LED on the front

of the BocaNET-24. If any ports are currently partitioned, the

corresponding LED will be REDRED

The BocaNET-24 implements the Link test function as

specified in the 802.3 10BASE-T standard. It transmits Link

test pulses to any port after that port’s transmitter has been

inactive for a short period of time. The device connected to

the port will respond in the same manner. The Link Status of

ports 1-24 can be viewed on the bi-color LINK/PRT LEDs of

the BocaNET-24

.

If a successful link has been established, the

corresponding LED will be GREENGREEN

COLLISIONCOLLISION

COLLISION: This yellow LED lights whenever two or more

ports are receiving data at the same time (i.e., collision). In

this situation, the BocaNET-24 partitions (isolates) the

colliding ports. The colliding ports remain partitioned until

valid data is received on the colliding ports. At this time, the

partitioned port is reconnected.

The BocaNET-24 has one 10BASE2 (BNC) connector which

interfaces directly to a 10BASE2 (“thin” Ethernet) network.

The 10BASE2 connection must be to RG58 A/U or C/U 50-

ohm coaxial cable. The ends of the cable segment must have

50-ohm terminators installed. Up to 30 connections (taps)

can be made to a 10BASE2 segment. The BocaNET-24 is

connected to a 10BASE2 segment with a BNC T-connector,

which is illustrated on the next page.
