A 4.3″ TFT LED is displaying the images sent by the outdoor unit. There are 4 little touch buttons that allow users to access the outdoor unit live images even if there’s no call on course, the second button can call the audio extension if there exists, the third one is used for door opening, and the last one represents the OSD button. The communication with the DRC-4L is done on four wires.
The connection is extremely simple, the only thing that the installer should be careful is to respect the correspondence between wire color (from the CDV-43K) and the DRC-43K input ports .
