Display module (hereinafter referred to as module, equipment, product) - equipment designed to provide information to passengers of urban public transport by displaying audio-visual information and video content. It is produced in 3 modifications - main, master (-01), slave (-02). The main display module is an independent, automatic device that processes incoming data from external systems and forms a data stream with its subsequent display on the screen.
The master display module is a modification of the main one. The difference of this product is the ability to transfer the generated data stream to the display module slave. The slave display module is an additional display module that works in tandem with the master.
It is not an independent device, as there is no possibility to receive incoming data and form a data stream from them for displaying on the screen. The formed data stream is received from the master.
