DAQman got a reaction from Minghzeng in Consult about driver software of 'IOtech 6224'
The Encore software is archived here. However, support for it and the 6000 series product line is not readily available.

DAQman got a reaction from Creation Test Solutions in Trying To Config Two USB-1024LS in System (Using Universal Library)
VB6 examples are included with the InstaCal installation from the MCC DAQ Software CD. The typical location is ..\Public\Documents\Measurement Computing\DAQ\VBWIN\. The easiest way to augment your program would be to create a BoardNum1 and BoardNum2 variable and assign them the board numbers assigned by InstaCal. Then, all you have to do is duplicate the various functions, like cbDConfigPort and DOut, DIn, DBitOut, or DBitIn that you may be using.

DAQman got a reaction from Gwen in USB-TEMP thermistor measurement accuracy above 120 °C
The Steinhart–Hart linear approximation used by the USB-TEMP is accurate only over a limited range. Measuring temperatures above 120 degrees C is not recommended or supported.

DAQman got a reaction from kseidl3 in MCC USB-205 Sampling
There is no sample-hold circuit before the analog inputs. The time skew from channel to channel is the inverse of the aggregate rate, 500k or 2us. It's more noticeable at lower rates. For instance, sampling four channels at 1000 S/s is 1 / 4000 or 250us. However, this can be good because it allows the channel more time to settle down before the measurement.

DAQman got a reaction from jmeisser in How to write from multiple devices to the same output file
Use the Signal Adaptation module set to Linear Interpolation. Connect the faster channel to input zero and it will adjust the slower USB-TC data stream to match it.

DAQman got a reaction from Henry Ballard in TracerDAQ using Type K Thermocouples
You could have the thermocouple wired backward. That would explain the temperature drop when heat is applied.

DAQman got a reaction from EKT in DAQami not shows up after the DAQami splash screen
Now that you have installed DAQami on Windows 11, you must update InstaCal, too. Run the following installation, and then try DAQami again.

DAQman got a reaction from EKT in How to upgrade the USB-1608G firmware?
If the USB-1608G is plugged in, InstaCal should automatically detect it when started. If you've started InstaCal before installing the device, hit the refresh button or restart InstaCal. If it is not found, I encourage you to try another USB port or even another computer. If a second computer has the same issue, it's probably defective.

DAQman got a reaction from dodge_neon in ERB24 'No Error' stopping Time Control measurement in DASYLab
The USB-ERB24 can be susceptible to electrical and magnetic noise -RFI and EMI. If the USB cable is close to equipment that may radiate noise, reposition it elsewhere. Also, get a USB cable with ferrite filters like this: https://www.amazon.com/Tripp-Lite-Hi-Speed-Ferrite-U023-003/dp/B008VOPCGY/. The ferrite on both ends absorbs high-frequency noise and will help.

DAQman got a reaction from Anatoliy in VIs for Labview
The missing pallet happens from time to time, we're not exactly sure why. However, it's just a missing file - attached below. Copy it to the User.Lib folder in \LabVIEW 2021\user.lib\

DAQman got a reaction from Anatoliy in USB-1602HS-2AO not recognized by PC (Win11)
You must run InstaCal with the USB-1608HS-2AO so that it is added to the board list. When InstaCal is closed, it creates a file that LabVIEW reads, which is read once it is first started. So, always close LabVIEW before making changes to InstaCal, and always close InstaCal before starting LabVIEW. If you do this and LabVIEW cannot find the device, check your computer for duplicate copies of our files. Check your whole system for cb.cfg, cbw32.dll and cbw64.dll. The correct locations for these are:
C:\ProgramData\Measurement Computing\DAQ\cb.cfg
C:\Program Files (x86)\Measurement Computing\DAQ\cbw32.dll
C:\Program Files (x86)\Measurement Computing\DAQ\cbw64.dll
If you find files in other folders, delete them.
Regarding the TracerDAQ error, it uses DirectX9, and the error typically means your video card is unable to run DirectX.

Please review the following forum thread regarding Raspberry PI 5 support.

DAQman got a reaction from OscarP in Voltage not 0 in analog inputs (USB 201)
You can test the input (CH0) by connecting it over to the +V pin, which is +5 volt signal. Then connect the input to the ground (AGND) and it should read close to zero. Assuming this all work, connect your sensor's -U to AGND and +S to the input.

DAQman got a reaction from Scott C in OpenLayers C++ API
The USB-1604HS-2AO uses the Universal Library from Measurement Computing; it does not use OpenLayers.
-
DAQman got a reaction from Mare in Analog Output settings
DAQami cannot redirect the value from an analog input to an output. Instead, consider the DASYLab software, which can. If you have C or Python programming skills, you could do it using our Universal Library API. LabVIEW is another possibility.

DAQman got a reaction from stealth sniper in Nexys 4 DDR confused in setting the appropriate clock period in MIG to access ddr2 memory
"MIG.clk_ref_i." looks like a type-o that should have been written as "the MIG clk_ref_i input terminal."
Thanks for the heads-up on the broken link.

DAQman got a reaction from Vasanthakumar in USB-CTR08: High-speed counter/timer device with eight counter I/O
The USB-2416-4AO (and AI-EXP32) inputs can be individually set to either differential or single-ended. However, the device has only one A/D converter, which is shared among the channels. Because of this, the measurements are not truly simultaneous. For example, if the sample rate is 100 Hz, the gap from channel to channel is 10ms.
-
DAQman got a reaction from ThanhThe in Unipolar to Bipolar Converter
An example of unipolar is 0 to 5 volts. An example of bipolar is -5 to + 5 volts. The AD2 Scope inputs are bipolar. If your signal is unipolar, it can be shifted to appear bipolar using the Zero parameter found in the channel settings.

You can get 37-pin cables from L-COM. Here's an example of a 2.5 ft female cable.

DAQman got a reaction from ThanhThe in Amplitude Modulation
Generating an AM signal is simple. Start with a new workspace. Add a Wavegen instrument and configure it for Modulation, as shown. Set the Carrier frequency to 1 MHz. Turn off the FM channel. Configure the AM channel to be a Triangle wave at 10 kHz, as shown.
Demodulation can be done with a lock-in amplifier. Add a Scope instrument and enable Scope-1. Physically connect Scope-1 to the Wavegen channel in a loopback fashion. Start both the Wavegen Channel and the Scope. To demodulate the AM signal, add a Lock-In amplifier and configure it, as shown.
Next, add a second Math channel; select Simple instead of the Lock-In amplifier. Set the channel on the Simple math channel to M1. Set the operation to AC, and it will extract the AC signal from the first Math channel. The 10 kHz triangle wave is extracted from the 1 MHz Carrier wave using the Lock-In amplifier and a Simple AC math channel. Much more information can be found in the Waveforms Help.

DAQman got a reaction from Roman Slizynski in Terminal assignment and application display
In DAQami, the first four channels are the voltage inputs V0...V3 and the next four are T0...T3. DAQami AI0 is V0H, V0L, and AIO4 is T0H, T0L.
Use InstaCal first to configure the temperature channels, such as thermistor, RTD, thermocouple, etc. Thermocouples are straightforward to connect; however, the other sensor types require special wiring. InstaCal has a Show Connections button that will display a wiring diagram to make it easy.

DAQman got a reaction from Namder in Currently using DASYLab 13 and looking at upgrading to DASYLab 2022_1.
Open Packages->Data Acquisition in the Available Devices Configurator window and unselect the Omega Engineering OMB driver. This should remove the XML messages.
In the top image you provided, I can see that the Worksheet opened in DASYLab 2022. So, what do you mean when you say it appears not to have opened the file?
