How Do I Use Port 4 on the AT-DIO-32HS Board (or PCI-DIO-32HS)?
The 653x line of products have 4 available digital I/O ports. In handshaking mode, port 4 is reserved for the handshaking communication signals. If I am not in the handshaking mode, how can I use the port 4 to perform simple digital I/O operations?

How Can I Synchronize Two DAQCard-700/1200s?
I want to synchronize two DAQCard-700/1200s so they perform analog input using the same sampling clock. I am familiar with synchronizing devices using the RTSI interface, but DAQCards do not have access to the RTSI interface.

How Can I Calibrate My DAQCard-700?
Problem: How can I calibrate my DAQCard-700? Solution: Calibration is a two-step process: first, the board measurements must be compared to known voltages in order to quantify any offset or gain errors as calibration constants.

Problems Performing Double-Buffered Pattern Generation at the Rate Specified for the DIO-32HS with NI-DAQ 5.1
I am using a function generator connected to the REQ1 pin to control the timing of a double-buffered, 16-bit pattern generation. It works flawlessly at 800 kilowords/second; however, when I increase the rate to 1 megaword/second and beyond, I observe stuttering at half-buffer boundaries. In other

Can I Use A BNC-2080 With A DAQCard-700?
Problem: Can I use a BNC-2080 with a DAQCard-700? Solution: Yes, all you have to do is put the BNC-2080 into PC-LPM-16 mode. The pinout of the DAQCard-700 matches the PC-LPM-16 exactly, with the exception of the PC-LPM-16's +/-12 V lines (pins 21 and 20), which are not connected on the DAQCard-700.

Pulse Width Measurement Using 9513 Counters Requires an Input of at Least Two Pulses
I don't measure the correct pulse width value if I perform measurement on a single pulse input. I am using the example programs for pulse width measurements provided in LabVIEW (or LabWindows/CVI). The duration for which the pulse remains high (10ms or 1s) does not change the behavior. I am using a

Enabling Dithering on a Lab or 1200 Series Device
If you are programming with LabVIEW, use the MIO Configure VI. This function (or VI) enables dithering on the Lab and 1200 Series devices (except the Lab-PC+). Refer to the NI-DAQ Function Reference Help or the LabVIEW Help for more information about using this function or VI, respectively.
