About the Broadband Adapter

Although the Broadband Adapter and the modem are identical in
shape when viewed from the side, the cable connectors are different.
In addition, the cable connector on the modem is labeled “LINE”, while
the cable connector on the Broadband Adapter is labeled “LAN”.

About the Ethernet Cable

The Ethernet cable that should be used for connection with the
Broadband Adapter will be very similar in appearance to the phone cable
that is provided with the Dreamcast.  Be very careful not to connect the
wrong cable.

Pay attention to the following points when connecting the Ethernet cable:

Use the Ethernet cable specified by your service provider.  If your
service provider does not specify a particular cable type Sega

recommends that a category 5 UTP (Unshielded Twisted Pair) or STP
(Shielded Twisted Pair), 2-pair (4-wire) cable be used.

Ensure that the Ethernet cable is connected to the Ethernet
equipment as specified by your service provider.

Usage Precautions

Never connect a telephone line to the
Broadband Adapter. Doing so could
damage it.

Using an Ethernet cable other than that specified by your service provider,
or indicated above, or connecting the cable to something other than
Ethernet equipment, could damage the Dreamcast, the Broadband
Adapter, or the equipment the Ethernet cable has been incorrectly
connected to, or cause the Dreamcast, Broadband Adapter or incorrectly
connected equipment to malfunction.

Phone cable

Before contacting Sega or requesting service, please check the following:
1. Are you using the phone cable instead of an Ethernet cable?
2. Is the Ethernet cable firmly connected to both the Dreamcast and your

Ethernet equipment?

3. Is the Broadband Adapter correctly and securely connected to the

Dreamcast?

4. Are you using software that does not support the Broadband Adapter?

The Broadband Adapter can only be used with software that supports
its use.

5. Is the Ethernet cable the correct configuration for both the Broadband

Adapter and the Ethernet equipment you are using?  Check with your
service provider or the Ethernet equipment manufacturer to ensure that
the Ethernet cable configuration is correct.  The configuration for the
Broadband Adapter’s connector is noted below.
