Troubleshooting
Intermittent operation
The most common cause of this
problem is that the I/O bus speed
is in excess of 8MHz.
Reduce I/O bus speed to a
maximum of 8MHz (to change
the I/O bus speed, run BIOS
setup). See your computer
documentation for instructions on
running BIOS setup.
Vibrations or loose connections
exist.
Cushion source of vibration and
tighten connections.
The board is overheating.
Check environmental and
ambient temperature. See the
documentation for your computer.
Data appears to be invalid
The most common cause of this
problem is that the I/O bus speed
is in excess of 8MHz.
Reduce I/O bus speed to a
maximum of 8MHz (to change
the I/O bus speed, run BIOS
setup). See the documentation for
your computer for instructions on
running BIOS setup.
An open connection exists.
Check wiring to screw terminal.
Another system resource is using
the specified base address.
Reconfigure the base address of
the DAS-1800HC Series board;
refer to page 3-5 for more
information. Check the I/O
assignments of other system
resources and reconfigure, if
necessary.
System Lockup
A timing error occurred.
Restart your computer.
Computer does not boot.
Board not seated properly.
Check the installation of the
board.
The base address setting of the
DAS-1800ST/HR Series board
conflicts with that of another
system resource.
Check the base address settings of
your system resources; each
address must be unique.
The power supply of the host
computer is too small to handle
all the system resources.
Check the needs of all system
resources and obtain a larger
power supply.
