With the new display for customer counting, guests or visitors are informed before entering a building whether the maximum number of visitors has been exceeded or not. For this purpose, the displayed text can be freely defined in the MxMC settings. In the MxMC itself only the content may be changed directly. MxMC supports the RICH text format for adjusting color, font and/or font size. This is supported by the usual word processing programs such as Word. The user can create his own texts in form and shape using Word, for example, and insert them into the corresponding MxMC text field by using “Copy and Paste”. This also supports different languages in the display.
