When you specify a sample rate, an attempt is made to report data at that sample rate. We highly suggest DataqSDK. PGain index changes P rogrammable Gain table. GetDataFrameEx returns binary data. PChannel index changes P rogrammable Channel allocation table, or scanlist if you are using Dataq’s term. The availability of a transitional counters can be found in here. NET, please also check this one out:.

Sample out of possible range If you try to access the digital channel which is not available on datqa device, datq result is meaningless see below for further explanation. Trigger Level too low, and will be changed to Digital channel must be enabled to access the digital inputs To enable a digital channel, you need to use codes like this: All Valid Trigger Channel: Since the default gain of 0 is not a valid number, user must specify the range first before using the rate channel.

The availability of a digital inputs can be found in here.

Fired when an error is detected by the control. The minimum throughput rate for other 1xx is: To enable a digital channel, you need to use codes like this:. GetData returns waveform data as a variant of two dimension bit integer array. Count is an integer and defines the number of scans you are requesting.

Invalid key to DI! The included samples are mostly from VB6.

WinDaq add-ons is the only UltimaSerial product being supported actively, all other software products are in FREEZE state, meaning no more modification nor active support.

Please note the front-end circuit of DI has a low-pass filter and it may not respond ideally for high frequency signals.

A pre-assigned Serialnumber must be matched before the device is open. PGain index changes P rogrammable Gain table. Here is the map if you want to do it yourself:. For examples in other programming languages, please visit our classroom.


The EventLevel property allows you to specify when you want the NewData event fired. Trigger Level too high, and will be changed to One frame is equivalent to one sample of each active channel. When you specify the channel count in UltimaSerial, like: MatchSerialNumber if this is set.

Channel Count changes to 1 ChannelCount Reads the number of currently enabled channels Variable: A trigger event will be fired when the trigger condition is met.

The event NewData fires whenever a set number, or more, of new data points have been gathered. Sorry, but the pattern of the square wave cannot be controlled. There are multiple functions for this property. When Ultimaserial is first loaded, the channel allocation table is 1, 2, 3, The default is 1 channel.

Each channel can have two limit lines, one for high limit and one for low limit.
