Chapter 1: Overview

Note

10/100Base-TX Twisted Pair Port

The 10/100Base-TX twisted pair port is described below:

Type of

Connector

The 10/100Base-TX twisted pair port on AT-PC232/POE Media Converter
features an 8-pin RJ-45 connector. The port uses four pins when
operating at 10 or 100 Mbps. For the port pinout details, refer to Figure 17
, “RJ-45 Connector and Port Pin Layout” on page 54.

Port Speed The 10/100Base-TX twisted pair port can operate at 10 or 100 Mbps. The

speed is set automatically through Auto-Negotiation or you can set the
speed manually via the DIP switches located on the back of the unit. With
Auto-Negotiation, the speed of the port is set automatically by the
converter after it determines the speed of the end-node connected to the
port. Auto-Negotiation is designed to ensure that the port on the converter
and the end-node are operating at the same speed and that they are
communicating at the highest possible common speed of the devices.

Duplex Mode Duplex mode refers to how an end-node receives and transmits data. If an

end-node can receive or transmit data, but not both simultaneously, the
end-node is operating in what is referred to as half-duplex mode. If an
end-node can both receive and transmit data simultaneously, the end­node is said to be operating in full-duplex mode. Naturally, an end-node
capable of operating in full-duplex can handle data much faster than an
end-node that can only operate in half-duplex mode.

The twisted pair port is IEEE 802.3u-compliant and will Auto-Negotiate the
duplex mode setting. It can be manually reconfigured to either full or half­duplex mode via the DIP switches located on the back of the unit when the
Auto-Negotiate switch is in the OFF position.

18

Maximum

Distance

In order for a converter port to successfully Auto-Negotiate its
duplex mode with an end-node, the link partner should also be using
Auto-Negotiation. Otherwise, a duplex mode mismatch can occur.
While configured for Auto-Negotiation, a converter port will default to
half-duplex if it detects that its link partner is not using Auto­Negotiation. This will result in a mismatch if the end-node is
operating at a fixed duplex mode of full-duplex.

The 10/100Base-TX twisted pair port has a maximum operating distance
of 100 meters (328 feet).

AT-PC232/POE Media Converter Installation Guide

Type of Cabling For 10 Mbps, the port requires Category 3 or better 100 ohm shielded or

unshielded twisted pair cabling. For 100 Mbps operation, the port requires
Category 5 or Enhanced Category 5 (5E) 100 ohm shielded or unshielded
twisted pair cabling.

Auto

MDI/MDI-X

The 10/100Base-TX twisted pair port on the AT-PC232/POE Media
Converter is auto-MDI/MDI-X and IEEE 802.3ab-compatible. The port
uses the auto-MDI/MDI-X feature to automatically configure itself as MDI
or MDI-X when connected to an end-node. Consequently, you can use a
straight-through twisted pair cable when connecting any network device to
a port. The Auto MDI/MDI-X feature is always enabled even when the
Auto- Negotiate feature is turned off and the speed and duplex mode on a
port are set manually.

Port Pinouts For the pinouts of the port when it is operating at 10 or 100 Mbps in the

MDI configuration, refer to Table 11, “MDI Pin Signals (10/100Base-TX)”
page 54. For the pinouts of the port when it is operating in the MDI-X
configuration, refer to Table 12, “MDI-X Pin Signals (10/100Base-TX)”
page 55.
