Firmware Update (Smart Firmware Update)

A HDD unit must be installed on the machine to enable the SFU or the package firmware update via SD

Each firmware module (such as System, Engine, etc.) used to be updated individually. However, an all-inclusive

firmware package (package_ALL) is now available.

There are several ways to update using the firmware package.

Package Firmware Update via a network: SFU (Smart Firmware Update)

There are two methods for SFU.

Immediate Update: To update the firmware when visiting

Update at the next visit: To set the date and time for downloading. The firmware will be automatically

downloaded beforehand and updated at the following visit.

"Update at the next visit" is recommended since firmware download may take some minutes due to the

network condition.

SFU requires the connection to @Remote via a device which has the embedded @Remote

communicating function. When a machine is connected to @Remote via an intermediate device (RC

Gate), the SFU function is disabled.

Other than SFU, package firmware update can also be performed by using the following three methods.

Package Firmware Update via a network: ARFU (Auto Remote Firmware Update)

Package Firmware Update via an SD Card

Package Firmware Update via a network: RFU (Remote Firmware Update)
