Table 5-1. Troubleshooting Information
Symptom
Board does not
respond
Intermittent
operation
Possible Cause
Base address is incorrect or not
consistent with what the program
is addressing.
The interrupt level is incorrect or
not consistent with what the
program is addressing.
The board configuration is
incorrect.
The board is incorrectly aligned
in the accessory slot.
The board is damaged.
The most common cause of this
problem is that the I/O bus speed
is in excess of 8 MHz.
Possible Solution
Check the base-address-switch setting.
If the base address is set correctly, make
sure no other computer device is using
any of the I/O locations beginning at the
specified base address. If necessary,
reconfigure the base address. Refer to
for instructions on setting the base
address.
Make sure no other computer device is
using the interrupt level specified in
your program. If necessary, reset the
interrupt level.
Check the remaining settings.
Check the board for proper seating.
Contact the Keithley MetraByte
Hardware Applications Engineering
Department; see "Technical Support"
on page 5-5.
Reduce I/O bus speed to a maximum of
8 MHz (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.
The board is overheating.
Electrical noise exists.
Cushion source of vibration and tighten
connections.
Check environmental and ambient
temperature. See the documentation for
your computer.
Provide better shielding or reroute
unshielded wiring.
