Chapter 1: Overview

Twisted-Pair Ports

The AT-GS2002/SP Media Converter features one twisted-pair port that is

10Base-T, 100Base-TX, and 1000Base-T compliant and has a maximum

operating distance of 100 m (328 feet). You can configure this port for

Auto-Negotiation or you can configure the port’s speed and duplex mode

manually. This port is labeled “Port 2” on the front panel. Refer to Figure 1

on page 19 for its location.

Note

Refer to “DIP Switches” on page 26 and Table 7, “Rear Panel DIP

Switch Settings” on page 34 for information on how to configure the

Auto-Negotiation feature and the speed and duplex settings.

The twisted-pair port features an 8-pin RJ-45 connector. For the port

pinouts, refer to “Connectors and Port Pinouts” on page 50.

Cable

Specifications

The cable requirements for the twisted-pair port on the AT-GS2002/SP are

listed in Table 1.

MDI/MDI-X

Mode

This twisted-pair port features auto-MDI/MDI-X when operating at 10, 100,

or 1000 Mbps. A port is automatically configured as MDI or MDI-X when it

is connected to another Ethernet port. Consequently, you can use a

straight-through or cross-over twisted-pair cable when connecting any

type of network device to this port on the media converter.
