How do I Set Programmable Power Up States and What Boards Support them?

Primary Software: Driver Software>>NI-DAQmx
Primary Software Version: 7.2
Primary Software Fixed Version: N/A
Secondary Software: Utility Software>>Measurement & Automation Explorer
Hardware: Digital I/O (DIO), Multifunction DAQ (MIO), Counter/Timers (TIO)

Problem:
How Do I Set Programmable Power Up States and What Boards Support Them?

Solution:
You set power-up states in MAX. You also can set power-up states with the DAQmx Set Power Up States (Digital) function/VI, but using MAX is the recommended method.

You can set the state of physical channels, including ports, for static DIO (digital input/output) devices when your computer is powered on or the device is reset in NI-DAQmx. The states are logic low (0 V-0.8 V), logic high (2 V-5 V), or tri-state (floating). You can only specify a programmable power-up state of tri-state on devices with configurable direction.

Note: I/O direction on static DIO devices is port configurable only. Therefore, you can set the power-up state to tri-state only on a port-by-port basis. You can, however, set individual digital output lines in a port to logic low or logic high.

Caution: Devices have limited numbers of writes to the EEPROM, so change power-up states infrequently.

Setting power-up states in MAX:
  1. Open MAX.
  2. Under Devices and Interfaces»NI-DAQmx Devices, right-click on your device and select Properties.
  3. Modify the power-up state.
  4. Click OK to write the settings to the device.
  5. Click on Reset Device for the settings to take effect.
Setting power-up states in LabVIEW:
  1. Place the NI-DAQmx Set Power-Up States VI on the block diagram.
  2. Set the inputs "device in" and "power up states"
  3. Add additional VIs to perform any other tasks within your program.
  4. Run the program to write the settings to the device.
The following devices support programmable power up states:
6509
651x (6511, 6512, 6513, 6514, 6515)
652x (6527, 6528),
All M Series boards
