DoorBird module port converter D21x for the connection of a second input module

DoorBird module port converter D21x for the connection of a second input module (e.g. keypad module with 12 buttons, MTM18A, MTM56A, MTM14E)

In the standard version, the D21x series of DoorBird IP video door stations offers one port each for the connection of input modules (red), e.g. keypad or multi-user modules, and one port for the connection of output modules (green), e.g. display or info modules. The module port converter offers the possibility to convert the port for output modules (green) into another port for input modules (red), e.g. to operate a keypad and a multi-user module simultaneously. When using the module port converter, it is not possible to use output modules on the port. The module port converter can be used for the following combinations:

Combination A

Port (red): Keypad module with 12 keys or fingerprint reader module 50

Port (green) with module port converter: MTM14A or MTM18A
