Express 3100 not detected.
The Express 3100 may not be detected for several reasons.
1.
Verify the following:
a.
The Express 3100 is powered on.
b. No other applications are running that could be using the
COM port to which the Express 3100 is attached.
A Windows application does not have to be active to tie up a
COM port. Be sure to check the Windows 95/98 Taskbar for
any suspended applications (such as HyperTerminal) that
may be using the COM port. If any applications are mini-
mized, they must be closed before starting the ADTRAN
Express Configuration program.

DIP switch 1

Confirm that the computer has a 16650 UART.
Difficulty with 230.4 kbps operation.

Windows) to 230.4 kbps, verify the following:

Off (up)

A high-speed serial card with a 16650 UART is being used, and
the software drivers to support the extended baud rate tables are
installed.
