2. Verify "WIS" chips using the following command:

lsusb | grep "WIS" | wc -l


3. This will display the number of chips detected which should match the number of inputs you have. This should be in increments of 8 (example: if you have 2, 8-channel encoders, you should see 16 here). If it is not in increments of 8 (example: 12) then there is most likely a problem with the chips inside the encoder unit.


4. If it is lower than what you have physically (example: you have 2, 8-channel encoders and you only see 8) check the following to find the cause:

a. Check or swap the usb cable

b. Check the power on the encoder unit.

c. Make sure that you are using the correct usb port on the DVR or base unit.
