Baud
Baud, abbrev.: Bd = unit for the data transmission speed. Do not confuse baud with "bits per second"
(bps, bits/s). Baud indicates the number of changes of state (steps, cycles) per second over a
transmission length. But it is not defined how many bits per step are transmitted. The name baud can
be traced back to the French inventor J. M. Baudot whose code was used for telex machines.
1 MBd = 1024 x 1024 Bd = 1 048 576 Bd

Boot loader
On delivery
ecomatmobile
controllers only contain the boot loader.
The boot loader is a start program that allows to reload the runtime system and the application
program on the device.
The boot loader contains basic routines...
• for communication between hardware modules,
• for reloading the operating system.
The boot loader is the first software module to be saved on the device.
