S0-Attachment

Block diagram for S0 attachment

The FPGA regulates the S0 flow of data between the S0 attachment and the
BusCPU on the 4FTR or LCPU. Here the BusCPU is the interface to the DVS-21 and
the S0 attachment the interface to the outside world.
The microprocessor controls the other functions such as e.g. LEDs on the 4FTR.
The display is an aid to programme the telephone numbers for the person doing the
commissioning.
