Express 3000 SP not detected.

The Express 3000 SP may not be detected for several reasons.

1. Verify the following:

a. The Express 3000 SP is powered on.

b. No other applications are running that could be using the

COM port to which the Express 3000 SP 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

Off

(up)

3. Confirm that the computer has a 16650 UART.

Difficulty with 230.4 kbps operation.

If the Express 3000 SP does not work when the DTE rate is set (inside

Windows) to 230.4 kbps, verify the following:

DIP switch 1

on the back of the Express 3000 SP is set to

Off (up)

2. 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.
