Hello @Ross MacKenzie. No records are available for external requests.

Hello @Ross MacKenzie. Digilent does not make our products in line with/accredited by ISO. This includes MCC hardware and software. Regards, Fausto

Hello @fmendoza711. The WebDAQ 504 supports saving data from all four input channels to a SD media, up to the maximum sampling rate of 51.2 kS/s per channel. Consider a SDXC card (U3, A2, V30 or newer) with minimum write speeds of 90MB/second and a supported capacity up to 2TB. Format the SDXC card for an ext2/ext3 or ext4 file system. Regards, Fausto

@metalhouse, On the USB-2416-4AO, the DIO# channel(s) can be configured as digital output(s) via the software application. Regards, Fausto

Hello @sathvikum. Please review the following forum post. (Note: the master branch for the MCC DAQ HAT Library for Raspberry Pi will be updated to v1.5.0.0 in the near future.) Regards, Fausto

Hello @metalhouse. The USB-2416-4AO can sink up to 150 mA max (per eight channel DIO bank) and supports a voltage level of +15 V. Take a look at the following solid-state relay (SSR). https://www.phoenixcontact.com/en-us/products/solid-state-relay-module-emg-17-ov-ttl-24dc2-2943259?type=pdf https://www.phoenixcontact.com/en-us/products/solid-state-relay-module-emg-17-ov-ttl-24dc2-2943259 The +5 output terminal 35 can source 10 mA max. for the SSR.

Hello @Przemek. Please investigate what changes were made recently to your application, i.e. OS update/upgrade, new host PC, updated DT software, IT changes to PC. What type of environment is the DT9805 module in during operation, to suspect a broken connection? Please test the DT9805 with Data Translation's QuickDAQ application on that system. Any issues? Please test the DT9805 with a different PC and Data Translation's QuickDAQ application. Any issues? If you have a backup DT9805 module, please swap the modules and retest. Please swap out the USB cable and retest. If you use a USB hub, retest with an externally powered USB hub or connect the DT9805 directly to the target system. Regards, Fausto

Hello @metalhouse. The DAQami software does not support an automation process. Take a look at the DASYLab software for your application. If you are a LabVIEW user, then you can use Universal Library for NI LabVIEW™ with the USB-2416-4AO and LabVIEW. Regards, Fausto

Hello @msmith. The MCC USB-3101FS has a low output impedance of 0.1 Ohms and an output update rate up to 100 kS/s per channel. The MCC PCIe-DAS1602/16 has an input impedance of 10 MOhms and an aggregate sampling input rate of 100 kS/s, since the analog inputs are multiplexed to the ADC. What is the output rate and output range of the signals from the MCC USB-3101FS channels? Configure the analog input channels on the MCC PCIe-DAS1602/16 board for differential mode. What is the input range of the analog input channels on the MCC PCIe-DAS1602/16 board? Choose a narrow range. Regards, Fausto

Hello @DHMPM. A 3D drawing with dimensions is not available for the MCC USB-201 and USB-204 devices, only a 2D drawing. There is no information regarding the depth of the holes. However, as shown below, the outer four holes attach the upper and lower sections of the enclosure, while the inner through holes can be used for mounting the device. Regards, Fausto

Hello @fdix. Please uninstall Data Translation's QuickDAQ software via Windows Control Panel. Run appwiz.cpl to access the Control Panel. Next, download and install Data Translation's OMNI software, which includes QuickDAQ. Does the new installation resolve your issue? Regards, Fausto

Posted for @fahiz. I am currently developing a custom GUI with Qt, which includes an oscilloscope. I'm utilizing the ADP 3450. My task involves plotting waves with a frequency of 1 million Hz and an amplitude of 1 Vpp. Additionally, it operates in burst mode with a trigger interval of 1 second. Currently, I'm employing FDwfAnalogInAcquisitionMode as scanmodeshift. I'm encountering below issues: The time range is very limited (currently at 0.2 seconds), which prevents me from observing more than one wave bunch. Ideally, I would like to visualize multiple pulses over a couple of seconds. Another issue lies in the plot amplitude, which doesn't reach 0.5 V and -0.5 V. but, increasing the frequency allows it to touch the peaks. Could you advise on how to address these issues and suggest the correct method for plotting in such cases? I am adding one screenshot also with this. I am using the SDK (C++) provided by Waveform, and the Qt version is 5.15.3. I am generating and plotting with the same device (ADP 3450). I also attempted generating from another source. I am providing the header file and source file of the basic Qt code (I am using QCustomPlot for plotting).

Hello @Ayesha Zaman. The AD2 LabVIEW driver is a legacy package. Please reference the Getting Started with LabVIEW and a Digilent Test and Measurement Device page. Regards,

Hello @Arnaud. Yes the DT9829 is supported under Windows 11 and with LabVIEW (using DT LV-Link3). Regards, Fausto

Hello @DHMPM. Please reference Figure 8 on page 13 of the MCC USB-201 User's Guide. Regards, Fausto
