What is “Firmware” and where is it located?
Firmware is code implemented within a peripheral’s ROM. In the case with the RCD-1000, 5020, 5040 and 4 X 4 we are using a “flash ROM” meaning a user can upgrade it should it be nescessary. The RCD-202 firmware cannot be upgraded. The “Firmware” can and needs to be updated once in a while, in order to ensure the RCD s compatibility with a newly updated operative-system or hardware for example.
