TROUBLESHOOTING: Can not activate all output

If you notice that you can not activate all relay output (and you don't hear the "click" when activating/deactivating the output), this can be caused by one of the following issue:

• The USB port of your computer should have 500mA to operate the 8 output
• The USB cable is too long and thus the power that reach the unit is not sufficient
•  The relay may be broken, create a support ticket and contact us for support
