Express 3000 not detected.
The Express 3000 may not be detected for several reasons.
1. Verify the following:
a. The Express 3000 is powered on.
b. No other applications are running that could be using the
COM port to which the Express 3000 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.
2. If you are operating at 230.4 kbps, move DIP switch 1 to
Off (up) .
3. Confirm that the computer has a 16650 UART.
External analog modem not detected.
Verify the following:
1. The external analog modem is powered on.
2. The external analog modem is properly installed and configured
for use with the Express Configuration program.
