The measuring data on the video monitor is constantly updated. For this purpose the MINISPEED 2000 has a Genlock-Interface which synchronizes the signal of the video monitor with the updated measuring data. The outgoing signal of the MINISPEED 2000 can be recorded with every video recorder and can be shown on every video monitor.

The data is displayed on a background lighted LCD display with 16 alphanumeric characters.

The power is supplied by the car battery. When the instrument is turned off the real-time clock causes about the same run-down of the battery as the self-discharge of the accumulator.

Software

The program for the MINISPEED 2000 has been written by using a MCS-51 assembler to fully use all possibilities of the processor and to obtain an optimal accuracy and reaction speed of the system. Since the program is saved in EPROM it is secured against external influences.
