Possible Solution
Board does not
respond
Base address is incorrect or not
consistent with what the program
is addressing.
Check the base-address-switch setting
on the board against the setting shown in
the configuration utility. 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
page 3-3 for instructions on setting the
base address.
The board is incorrectly aligned
in the accessory slot.
Check the board for proper seating.
The board is damaged.
Contact the Keithley MetraByte
Hardware Applications Engineering
Department; see page 8-5.
Intermittent
operation
The most common cause of this
problem is that the I/O bus speed
is in excess of 8 MHz.
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.
Cushion source of vibration and tighten
connections.
The board is overheating.
Check environmental and ambient
temperature. See the documentation for
your computer.
Electrical noise exists.
Provide better shielding or reroute
unshielded wiring.
Low or no output
voltage
Trying to drive a load of less than
5 mA
Reduce load or buffer the DAC output
