61203153L3-20 Express 3000 SP User Manual 8-3
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
to
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:
1.
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.
