Possible Solution
Data
appears to
be invalid
The most common cause of this
problem is that the I/O bus
speed is in excess of 8 MHz.
Reduce the I/O bus speed to a maxi-
mum of 8 MHz (to change the I/O
bus speed, run BIOS setup). See
your computer documentation 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
PIO-24 board. Check the I/O
assignments of other system
resources and reconfigure, if
necessary.
Computer
does not
boot.
Board not seated properly.
Check the installation of the board.
The base address setting of the
PIO-24 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.
System
lockup
A timing error occurred.
Restart your computer.
