• NI 6154 Devices—By default, the digital output lines
(P1.<0..3>/PFI <6..9>) are disabled (high impedance) at power up.
Software can configure the board to power up with the entire port
enabled or disabled; you cannot enable individual lines. If the port
powers up enabled, you also can configure each line individually to
power up as 1 or 0.
Refer to the NI-DAQmx Help or the LabVIEW Help in version 8.0 or later
for more information about setting power-up states in NI-DAQmx or MAX.
