The MMIS control unit of the MESA 23 train radio family is designed for menu-guided control of digital and analogue train radio. It fulfils the requirements for use on rail vehicles and is designed for console installation in the driver's cab. With the aid of an intercom system consisting of a handset and loudspeaker, the train driver is able to carry out a wide range of communication tasks.
Funkwerk's MMIs are developed in accordance with specifications and European standards and are characterised by their innovative and intuitive user interface. Apart from key functions that are always within reach, our control units are mainly controlled via softkeys. This makes operation easier for the user and also allows the flexibility to make functional changes without the need for hardware.
Enquire nowThe CENELEC standard „MMI Symbols for ERTMS/ETCS/EIRENE-MMI“ was used for the design of the key symbols. The extensive railway-specific functions are mainly controlled via the keypad with its 9 hard keys and 14 soft keys.
Hardkeys
Keys with fixed function assignment independent of the current menu level. The following functions are designed as hard keys:
Emergency call
Call to the dispatcher
Call to the train attendant
Train announcements
Call Lok - Lok
Up direction button
Down direction button
Confirmation of the selection made
Resetting the train radio system
All other operating functions are activated via softkeys.
Softkeys
The functional assignment of the softkeys is shown in the immediately adjacent area of the display and depends on the radio system set and the current menu level.
Consistent assignment of functions to the same softkeys in the menu levels and an optimised display size make it easy for the driver to perform all operating actions during the journey.
