Why do my DMP801 meters not work?

If your channel assignment within the DMP801 software is correct but your “output” meters are not reacting, be sure to double check “DIP6” on the rear of the DMP801. This DIP will deactivate the systems’ VR which can result in the issue you’re experiencing. The image below indicates the exact DIP switch that needs to be adjusted to resolve this issue. The lower position means the VRs are locked while the upper position means they are unlocked.
