INSTALLING THE ADTRAN EXPRESS XRT
This section describes how to connect the Express XRT to a com-
puter and how to install the Express Configuration Wizard soft-
ware.
Verify Switch Settings
Dip switches 1 and 2 located on the rear panel of the Express XRT
allow you to physically configure certain settings. Figure 2-1 on
page 6 shows the location of the dip switches on the rear panel of
the unit.
The factory default position for all switches is On (down) during initial
installation.
If dip switch 1 is set to the Off position (up), the unit is set to op-
erate at a DTE speed of 230.4 kbps. A special serial COM port us-
ing a 16650 UART is required while in this mode. If switch 1 is set
to the On position (down), the unit will automatically adapt to the
DTE rate (up to 115.2 kbps).
In order to configure the Express XRT to operate at 230.4 kbps with
Windows 95 or Windows NT 4.0 Dial-Up Networking, a new modem
must be added from the
Modems
icon in the Control Panel. Enter the
name for this new connection and select
