Hello, There's no Python support for the Data Translation products. Currently, there is an issue with support for MatLab 2022 however, you have 2021b so it should work. Check the MATLAB software manager to see if the support is enabled. best regards, John

Hello, We saw issues on upgraded computers when people were making the jump to Winidows 10 and a simple software reinstallation fixed it, try reinstalling QuickDAQ or the Omni CD. The Data Translation software can be found on the following page: https://www.mccdaq.com/downloads/DTSoftware/ best regards, John

Hello, We've never promoted the abilty to read back an output port value because it was not throughly test. However, reading back a value from an internal register does not assure that the port is set to the read back value. Because of this and because the ability to read back port values was never throughly tested, we recommend to programmers that they maintain a program variable that reflectw the last written port value. Best regards, John

Hello, The a_out_scan buffer channels must be interleaved. Attached is my python script that generates a 1000 Hz square wave on both channels. The channels output a +/-10 volt square wave. In D/A counts, the values are 0 for -10 volts and 65535 for +10 volts. 32767 is zero volts. Each volt is roughly equal 3276 counts. best regards, John a_out_scan_231.py

Hello, Check the installed version of InstaCal and if it is less than 6.73 update it with the link below. https://www.mccdaq.com/downloads/InstaCal/icalsetup.exe best regards, John

Hello, The 5-volt range accuracy is +/- 3mV when operated at 25-degree C. However, the MCC 128 may not be at 25-degree because the Raspberry PI does get warm, and this heat warms the MCC 128. My recommendation is to first measure the laser sensor signal using a calibrated bench voltmeter to know the true value. Assuming this confirms the 0.19mV value, see if you can get a taller Raspberry PI header. This will lift up the MCC 128 allow a bit more air flow underneath. Modify your python script to produce an average value of 167 readings. 167 @ 1000 Hz is an average over one 60 Hz cycle. This helps reduce noise from the surroundings. If these suggestions don't pan out let me know the board's serial number. If you can't get to the serial number then please provide the sales order or purchase order number. Best regards, John

Hello, The USB-1608G series devices are normally used with the built-in OnBoardClock. When the scanning process is started, the clock signal is ouput to the AICLKO terminal. To make two of them work together, set one to ExternalClock and the other to OnBoardClock. Connect the AICLKI pin on the ExternalClock device to the AICLKO on the OnBoardClock device. Because the ExternalClock device is dependent on the OnBoardClock device, you must start its task first. If not the OnBoardClock will already be running when the ExternalClock device is started and the two will not be synchronized. For an example, see example ULx Acq&Graph Voltage-Ext Clk.vi that is located in \Examples\ULx\Analog In\Measure Voltage.llb library. I believe you could duplicate the block diagram making sure each is set to the correct device. Then set the clocks appropriately and route the Error wires so that ExternalClock task is started before OnBoardClock's. Best regards, John

FYI, for differential measurements, add ul.a_input_mode(board_num, AnalogInputMode.Differential) before the ul.a_in_scan function. John

Hello, Take a look at the attached script. It's similar tot the a_in_scan_continous.py except it prints a line a data after it determined that a half buffer of new data is available. It prints one scan from the half buffer because printing lots of data to a console make it hard to print other messages and it's a slow process. The loop terminates when 200000 samples (50,000 per channel) have been collected. You would turn on the load before executing the ul.a_in_scan() and off after ul.stop_background. Then set ul.a_in_scan() to read the next channel and do it again. Or, continuously read all four channel controlling the loads from within the while loop. Best regards, John a_in_scan_USB200.py

Hello, I can check and see what's possible however, I need the board serial number(s) and their MCC sales order or purchase ordre number(s). Best regards, John

Hello, Install the InstaCal utility, install the USB-1608G and start InstaCal. It will locate the device and add it to the board list. This is required for the free TracerDAQ program. If you're going to use the DAQami program, watch the video on the DAQami product page. You will need a key to unlock for perment use. In this case, go to https://www.mccdaq.com/support/daqamikey.aspx and register to receive your free key. If you need further assistance, please explain what want to do. Best regards, John

Hello, The WebDAQ devices can be used only with mail services that allow signing in with a username and password. It does have the ability to negotiate security with the mail server. Perhaps you could find a third party mail service that still allows username/password login. I tried both gmail and yahoo but could not get them to work with my WebDAQ. I suspect most mail servers have security that exceed our WebDAQ email abilities. I will file a defect report and hopefully when new firmware is posted, it will fix the email issue. Best regards, John

Hello, Windows 11 requires InstaCal 6.73, which you can install from our latest CD download: https://www.mccdaq.com/downloads/MCCDaqCD/mccdaq.exe Best regards, John

Hello, Contact IFM regarding their wiring diagram and how to connect it to an analog input. The USB-1608G maximum input range is 10 volts with protection to 20 volts. Use a 10 volt power supply to avoid exceeding our 10 volt input range. best regards, John

Hi Rob, I don't see anything obvious but then again I can't simulate your system. If this is a critical application, I can recommend a consultant to help figure it out. best regards, John

Hello, Use the following link to download our DAQ Software CD. https://www.mccdaq.com/downloads/MCCDaqCD/mccdaq.exe best regards, John

Hello, I'm sorry, but MCC no longer provides phone support. We switch to this forum so that questions and answers are searchable to everyone. The MCC 128 installation instructions can be found on this page: https://github.com/mccdaq/daqhats After installation, examples for all the MCC daqhats will be in `/daqhats/examples/ Best regards, John

Hello, My suggest is to start a new worksheet and put down only a Data Translation Analog Input module. Set the module to the DT9816 board and press Start. If you don't get an error then DASYLab can control it. If you cannot set the module to the device, remove it and restart the computer. Plug it back in after the restart and try the above test again. If it works, attach your worksheet to your reply. Best regards, John

Hello, Error 6623 is undocumented and does not happen often. However, the few past incidents point to the device itself. If you are on a Windows 11 Computer, make sure the InstaCal utility is version 6.73. Otherwise, if it is possible try a different E-1608. Best regards, John

Hi Brad, Assuming you have channels enabled, it could be that the program itself needs more permission. Using File Explorer, find C:\Program Files (x86)\Personal DaqView\Applications\pdaqview.exe. Get the properies and on the Compatibility page, set Run this program as administrator. Also, the top title bar of the program should show something like PDAQxxxxxx, where xxxxxx is the serial number. This indicates it's talking to the device. John

Hello, Measurement Computing return policy is 30-days. The MCC 128 on PO 25522241 shipped on August 8 and allowing for one week delivery, you are still 10 days past. If it is still in the sealed static bag, I can make an exception. Best regards, John

Hello, A typical steady state temperature can move around due to noise on the input and on the thermocouple. However, 0.05 Degrees C is well within the accuracy of the device. My suggestion is to display data to one decimal place, which is more inline with it ability. Best regards, John

Hello, if the non-admin users get the screen with the "Remaining Time" on the evaluation period - see below, have them enter the license key. Daqami keys are now free and to obtain one go to: https://www.mccdaq.com/support/daqamikey.aspx If the evaluation period has expired, then as an admin uninstall Daqami followed by reinstalling. Your license key will be remember and it will run as it did before, but the non-admin users evaluation period should get be reset. Upon starting the program they should see the following: Press Enter Key and enter your key. After the they should have the ability to save data. Best regards, John

Hello, Your device was manufactured in 2007 and should work. However, I cannot explain why the software fails to find it. Usually this problem is caused when the device plugged in while Personal DaqView is running. That's why I asked to restart the program. Look in C:\Windows\System32\ There should be two DLL: pday.dll and pdaqx.dll. Both should have Date Modified of 2011. Look in C:\Windows\System32\Drivers\ There should be pdaq.sys file with a Date Modified of 2011 The other thing to check is if your system uses virtualization for security. Our product don't play well with virtualization. Best regards, John
