Please note:
in the following text, register addresses were given as hexadecimal numbers: 0x14 = “20” 14 hexadecimal = 20 decimal.
Bit 7 = MSB = “0” for all register addresses
Bit 7 = MSB = “1” for all commands and data
Firmware
The Scanner head contains Firmware in an Eprom, defining the
functions of profile recognition and Scanner head control
algorithms. This Firmware is referred to as “Scanner head
Firmware”. This Firmware can be altered by exchange of the
Eprom. Current Revision state is 3.6.3.
Firmware of the electronic system is located in the blue box
electronic system. This firmware can be updated with a flash tool
supplied by MEL on request. The flash procedure requires a
working RS-232 connection to the electronic box and a.m. flash
tool. Current firmware revision of the electronic system is 1.13.5
