Di-148u driver

This method must be invoked after Start. Data2Volt converts binary data according to the equation. Applicable Devices: DIx only.

If you try to access the digital channel which is not available on the device, the result is meaningless see below for further explanation. For some devices, digital inputs, same as transitional counters, are only available when a digital channel is enabled in the scan list:. To enable a digital channel, you need to use codes like this:. DigitalOutput dio. GetData ensures waveform data continuity by passing a continuous stream of data to your program.

GetData returns waveform data as a variant of two dimension bit integer array. To access the data returned by GetData, you can take a look at the following example If you are using VB.

NET, please also check this one out :. Chart Channel1 'Plot channel 1. As long as you don't ask for more than what UltimaSerial has in its buffer, GetDataEx, ensures waveform data continuity by passing a continuous stream of data to your program. For most C programmers, a variant of integer array returned by GetData is not what they would like to handle. In this case, it will be much easier to use GetDataEx to place the data directly to a pre-defined integer array.

Syntax: Dim A as integer Ultimaserial1. Count, an integer, is the number of data points, not scans, that you are requesting 32, maximum. The data will be aligned with the first channel.

If you enable more than one channel, you will have to sort out the data for each channel yourself. One frame is equivalent to one sample of each active channel. Click here to find out how to extract the data from the variant. Variables: Count is an integer and defines the number of scans you are requesting. The maximum number of scans you can request is 8, One frame is equivalent to one sample from every active channel.

GetDataFrameEx returns binary data. For example:: UltimaSerial. Count, an integer, is the number of data points, not scans, that you are requesting 30, maximum. This function is provided for primitive programming language that doesn't support variant output or array transfer. MapErrorMessage int errorcode as string maps the error code returned by the control to a brief description of the problem. Here is the map if you want to do it yourself:.

Original channel count is unmodified Sample out of possible range Invalid channel count.
