Local man machine
communication
Basic
The built-in man machine interface (MMI) provides local communication
between the user and the terminal.
Local communication also occurs with a PC connected to the built-in
MMI via a special optical interface. This communication works like the
remote communication within the station monitoring system (SMS)
described in the other corresponding documents.
This chapter describes in detail the structure of a local MMI, the basic
principles of local man-machine communication (MMC), and the basic
structure of a menu tree in a terminal.
Document 1MRK 580 158-XEN presents a detailed menu tree for all
REx 5xx series terminals in detail.
The MMI module consists of three light emitting diodes (LEDs), a liquid
crystal display (LCD), six membrane button, and one optical connector
that enables local man machine communication (MMC) with the aid of a
personal computer (PC).

Three LEDs provide primary information on the status of a terminal. Each
LED has a special function, which also depends on whether it is dark, has
a steady light, or a flashing light.
