INSTALLING THE ADTRAN EXPRESS XR/XRT

This section describes how to connect the Express XR/XRT to a PC 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 XR/XRT allow certain settings to be physically configured. Figure 2-1 shows the location of the dip switches on the rear panel of the unit.

The factory default position for all switches is down (On) during initial installation.

SW 1: Off (Up) =	230.4 kbps
On (Down) =	Autobaud (speeds up to 115.2 kbps)

If switch 1 is set to the Off position, the unit is set to operate at a DTE speed of 230.4 kbps. A special serial COM port using a 16650 UART is required while in this mode. If switch 1 is set to the On position, the unit will automatically adapt to the DTE rate (up to 115.2 kbps).

In order to configure the Express XR/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 ADTRAN Express XR or XRT 230.4 Kbps & 16650 UART. See the section Installing Windows 95 Dial-Up Networking.
