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 f
or its location.

Note

Refer to “DIP Switches” on page 26 and Table 7, “Rear Panel DIP
Switch Settings” on page 34 for informa
tion 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.
