(16) FIG. 4 shows a schematic, three-dimensional view of a further exemplary embodiment of a control unit. The control unit 1 has an operating side 3, a standard connection side 2 and a configuration connection side 4. The operating side 3 is oriented substantially horizontally. The configuration connection side 4 is oriented substantially vertically. The standard connection side 2 extends between the operating side 3 and the configuration connection side 4.

The first height is greater than the second height. As shown in FIG. 1, the first height is more than twice the second height. Due to the differences of the first height and the second height, the standard connection side 2 is arranged inclined. In particular, this means that an area orthogonal of the standard connection side 2 has a horizontal component and a vertical component.

(17) The standard interface 42 is arranged on the standard connection side 2. The standard interface 42 is formed by a plurality of connection means. The connection means of the standard interface 42 are designed as connectors. Exemplarily, the vacuum toilet connection means 10, the flush button connection means 12 and the voltage supply connection means 14 are provided with a reference sign. The standard interface 42 with the vacuum toilet connection means 10, the flush button connection means 12 and the voltage supply connection means 14 is arranged on a standard circuit board not shown inside the control unit 1. The connection means shown in FIG. 4 in the form of pin headers of the configuration circuit board arranged inside the control unit project through through-holes inside the standard connection side.

(18) A first configuration connection means 20, a second configuration connection means 22 and a third configuration connection means 24 are arranged at the configuration connection side 4.

(21) FIG. 6 shows a schematic, three-dimensional view of a further exemplary embodiment of a control unit. The control unit 1 again comprises a standard connection side 2 with a plurality of connection means. Furthermore, this comprises a configuration connection side 4 with a first configuration connection means 20, a second configuration connection means 22 and a third configuration connection means 24.

(22) The control unit 1, 1, 1, 300 shown in FIGS. 1 to 7 enables the efficient and cost-effective development as well as production of a mobile sanitary device 100. The standard interface 42, 311 on the standard printed circuit board 320 enables the standardized connection of standard components, such as a vacuum toilet 110, a flush button 120 and a power supply 130. However, since in the project-related business of mobile sanitation devices such rigid configurations are usually not sufficient, the control unit 1, 1, 1, 300 further provides the possibility to connect further components of a mobile sanitation device 100 to the configuration interface 44, 351. Such a non-standard component may be, for example, a frost drainage device.

(23) However, the control unit 1, 1, 1, 300 can always be provided as a standard component. Thus, the standard printed circuit board and the configuration printed circuit board and, if necessary, also the housing of the control unit 1, 1, 1, 300 are to be manufactured as standard. In the wiring harness as a specific component, the individuality is fully represented, so that the individuality is reduced to the wiring harness. By replacing the wiring harness, a completely new function can be implemented on the control unit 1, 1, 1, 300. If necessary, the entire control unit 1, 1, 1, 300 can be provided as standard. Thus, the control unit 1, 1, 1, 300 can be mass produced so that economies of scale are achieved and costs are reduced. Nevertheless, the control unit 1, 1, 1, 300 can be arranged in a wide variety of projects between the hardware components of a mobile sanitary device 110, 120, 130 and a control device 200 and still allows the mobile sanitary device 100 to be designed flexibly.
