Downloading Procedure - Canon iR4570 Series Service Manual

Dcon/Rcon is downloaded by way of the main controller unit.
- The DC controller PCB/reader controller PCB is equipped with a boot ROM, and downloading may be attempted
multiple times in the event of failure.
- The system software used in the DC controller differs between the iR3570/3570 and the iR2870/2270. The system
software designed for the iR4570/3570 is stored as iR3570, while the system software designed for the iR2870/
2270 is stored as iR2270. The machine has a mechanism to read the appropriate system software. It is a good idea
to download both types of system software.

You will not be able to download Rcon unless the DC controller has started up normally (as, otherwise, the power
supply control signal will not be valid and, as a result, the reader unit remains without power).

iR2270 / iR2870 / iR3570 / iR4570 / iR3530
You can execute a downloading session in either normal or safe mode. In the case of safe mode, however, you will
not be able to find out the version of Dcon/Rcon, causing all downloading to occur (overwriting of the same version
and downgrading).
