Cause

The current manual does not show where to connect the wires for the RS422

Resolution

The BU6 camera has a labeled connector for the RS422 positive and negative. This connector is the one that is shown as Alarm IN in the manual on the BU6. There is no Alarm In on the BU6. The C20-DW has a 8 pin connector on back and the RS422 wiring connects to the left side of that connector .it also has the UTP, alarm in and alarm out on it.
