If the machine fails to start up, be sure to replace the boot ROM.

17.4.8 Downloading Dcon and Rcon

17.4.8.1 Outline

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.
Service PC
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).

17.4.8.2 Downloading Procedure

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).
[Downloading Rcon]
1) Select the version of Rcon to download.
