The DV-4 distributor is a four-channel video signal splitter and number decoder for the CC-4000 digital video intercom system. The device is designed to connect Cyfral video monitors. It converts the symmetrical signal of video and uniphone lines into four channels for connecting subscriber monitors. The distributor has a built-in decoder of uniphone line physical addresses, which must be programmed before use. With this solution, there is no need to address each monitor and it is possible to connect up to three monitors in one apartment (internal intercom). In addition, the subscriber's monitor is not able to affect the operation of the rest of the intercom. The distributor is powered by a 12-13.8V DC power supply, the intensity of which depends on the number of powered monitors. It should be assumed that the power supply should have a capacity of 1A per monitor. In case the distributor does not power any monitor (locally powered monitors), the distributor can be powered from the CC-4000 control electronics board. The device is placed in a plastic housing.
