Product Reviews

What is the minimum time it takes to simultaneously read/write to multiple digital channels? (I would like to read/write digital signals at 1 kHz.)

The DT9817-H is a software polled device. Meaning that there is no onboard hardware clock to pace the read/writes to the digital I/O. The read/write are, therefore, dependent on the system and the software in use. The USB bus has high bandwidth, but timely access is much slower. We have no official benchmarks but a 1mSec update does not seem out of the question.

Hello. My customer want use DT9817-H with C#. so i informed the route of C# examples. but my customer need more information how to change the input channel to Output channel or Output to input. I know that it's in the manual but it's very hard to get. So could you give me some C# examples or let me know how to change the channel

The DT9817 and DT9817-H modules each have 28 programmable I/O lines that are organized into three 8-bit ports and one 4-bit port. Each port is considered a subsystem element. For each subsystem element, a user must decide whether all the bits are wired as inputs or outputs. When a user configures a digital subsystem, each subsystem element must be specified independently, before calling a get or set single value with an integer value, for that subsystem element

  • Once Open Layers is installed, look in the following location for examples: C:\Program Files (x86)\Data Translation\DotNet\OLClassLib\Examples\
  • Here is a code snipped for a setting a digital output:
  • doutSS = device.DigitalOutputSubsystem (x); // where x is the element
  • doutSS.DataFlow = DataFlow.SingleValue;
  • doutSS.Config ();
  • doutSS.SetSingleValue (y); // where y is a decimal value of which bits will be set high

Hellow! i want to simple Digital Input test with DT9817 with Quick DAQ but it does not work with DT9817. So is there any software to test Digital I/O with DT9817 before i give it to the enduser

Yes, you can test the DT9817 Series using our “QuickDataAcq.exe” test utility that installs with the Omni-CD installation. The Omni-CD can be downloaded from our FTP site here: https://www.mccdaq.com/downloads/DTSoftware/Omni-CD/. Once you have completed the installation of the Omni-CD please navigate to the C:\Program Files\Data Translation\Win32 directory. There you will see the QuickDataAcq.exe program. Double click the exe file to start the test utility. At the top you will see the test utilities toolbar. For digital inputs mouse over and left click the “Acquisition” menu selection. For digital output mouse over the “Control” menu selection and left click for digital output.
