Twisted-Pair Ethernet (TPE) cabling
===================================

The ATI AT-2400 adapter has an RJ-45 connector for 
use with TPE cabling. TPE cabling is also known as 
RJ-45 cabling, Unshielded Twisted Pair (UTP), and 10BaseT 
cabling.

For more information on the 10BaseT specification, contact 
your local network supplier or call the IEEE at 
800-678-IEEE.

Recommended cables
------------------

The RJ45 connector can use 22, 24, or 26-gauge UTP cabling. 
The cable must comply with the IEEE 802.3 10BaseT standard 
for Category 3, 4, or 5.

The cable between the computer and the hub or switch must 
be less than 100 meters long.

These UTP cables work well:

Manufacturer       Model number         No. of pairs
----------------------------------------------------
Belden             9562                 2
Data Set           2402                 4
Belden             9566                 6
Belden             1588A                2

Silver Satin is not within the 10BaseT specification and 
may not work or may work intermittently.


Cable and connector pinouts
---------------------------

If you need to repair a cable or provide connectors for 
UTP cable, wire straight through as shown in the 
following table.(A very few applications require a 
cross-over cable. To allow for a straight-through cable, 
the vast majority of hubs and switches provide an internal 
transmit/receive crossover function. This means the 
transmit circuit of the network card is connected to the 
receive circuit of the hub and vice-versa. Many hubs also 
have an external interface switch, the MDI/MDI-X switch.) 

Function    Pin#               Pin#
-----------------------------------
TX+         1    <-------->    1
TX-         2    <-------->    2
RX+         3    <-------->    3
RX-         6    <-------->    6

Use only four of the eight pins. Pins 1 and 2 must be a 
pair, and pins 3 and 6 must be a pair.


Common problems
===============

A hub can't detect a workstation
--------------------------------

This is often the result of a crossed wire in the cable or 
wiring closet. Make sure the wiring is correct.

Workstations can't connect to the network
-----------------------------------------

Reset or power off/on your hub or switch.

Polarity problems
-----------------

A common problem in 10BaseT wiring is crossing the positive 
and negative phases of the transmit and receive signals 
(for example, crossing pins 1 (TX+) and 2 (TX-)).
