When you launch any eDAQ software, the software will normally check to see if any eDAQ hardware is connected to the computer and turned on, and then the software will try to communicate with it. If the software cannot communicate with any eDAQ hardware, it will show one of the following messages:

  • Hardware Unit Unavailable, Chart is unable to find a Hardware Unit. (in Chart software)
  • Hardware Unavailable, Cannot find a hardware unit (in EChem and Scope software)
  • Hardware Unavailable, Cannot find a recording unit (in PowerChrom software)
  • Z100 Navigator, No device found (in Z100 Navigator software)
  • Device Selector, Please select a C4D device (in C4D Profiler V2 software)
  • Device Selection, Unable to detect any ER430 HV Sequencer units. (in QuadSequencer Software)


Chart software
EChem and Scope software
PowerChrom software


Z100 Navigator software
C4D Profiler V2 software
QuadSequencer software


You may want to continue in Analysis Mode. This lets you view a previously saved data file, analyse your data and save the data file, but you won't be able to communicate with any hardware or collect new data.

If you want to collect new data, you need the software to communicate with the hardware.

Perform the checks listed below. DON’T MISS ANY STEPS!

  1. Check the hardware unit is turned on! Make sure that the LEDs on the front of the hardware unit are lit. If you see red LEDs flashing on the front of the hardware unit, there is something wrong with the unit; please contact eDAQ.
  2. Make sure the USB cable is connected to the computer and to the hardware.
  3. Go to the [www.edaq.com/software-downloads software download webpage] and make sure you are using the latest version of the software. Don’t rely on using the software that came with the equipment. Older software versions won't be able to work with new hardware.
  4. Try a new USB cable. USB cables can break, so it’s a good idea to try a different one. eDAQ equipment uses either the standard USB cable used by other electronic devices like printers, or the micro USB cable.
  5. Try a different computer. A virus on a computer, or a computer with a defective USB connector, can stop the communication to the eDAQ hardware. Try installing the eDAQ software on a different computer and connecting the eDAQ hardware to that computer, to see if the same problem occurs
  6. Make sure that Windows is using the correct driver for eDAQ hardware. Do this by:
    1. Click the Windows key on your keyboard and type Device Manage
    2. In the Device Manage window, find your eDAQ hardware; it might be under the headings “eDAQ e-corders” or “Ports (COM & LPT)”
    3. Hover the mouse pointer over the eDAQ hardware and right click the mouse; select “uninstall”
    4. Turn off the eDAQ hardware, at the back unit
    5. Install the eDAQ software; make sure you are installing the latest version of the software downloaded from [www.edaq.com/software-downloads]
    6. When the software is installed, turn on the hardware unit to the computer; Windows should now install a driver
  7. If none of the above suggestions solve your problem, please could you fill in with as MANY DETAILS as possible, the Technical Help Request form


Note: To always run in Analysis mode. You may want to install the eDAQ software on a computer that will never be used to run experiments on. Maybe it’s a computer outside the lab, in your office or a personal laptop, on which you only want to view and analyse the data you collected in the lab. You can set the software so that, each time it’s launched, it won't check to see if eDAQ hardware is connected to the computer. You can set this by:

  • In Chart software, go to the menu Edit, select Preferences, Hardware Unit Startup, and click Always start in analysis mode
  • In PowerChrom software, go to the menu Edit, select Preferences, Hardware-Startup and click Always start in analysis mode
