9.4 Software Revision
The control board retains control software in its flash memory. Software revision can only be performed with
a flash memory loader. For more details, read the User's Manual supplied with the Flash Memory Loader.
Caution: The update software is overwritten on the existing software. While the flash memory loader is
loading software, never turn off the control board as the correct contents of software may be lost
permanently. Software containing bugs, if loaded, may cause malfunction of the control board or,
in the worst case, damage to the device electronics.
9.5 Registering User-Defined Fonts and Logos
This control board is loaded with flash memory, which can be used to register user defined bitmap images of
fonts or logos. Font/logo data, once registered, are held in memory until updated with other data. For more
information, read the Command Reference.
(1) Registering user-defined fonts
User-defined fonts are registered with the blank code page. They must be stored to the specified memory
address area and in the specified data length.
User-defined fonts must be registered in batch mode. While only a part of user-defined fonts can be
registered, it will be cleared when batch registration is initiated.
(2) Registering user-defined logos
One or more logos or bit images can be registered with flash memory. They are registered in ascending order
of registration numbers beginning with 1. Registration must be performed in batch mode, and you cannot
update only a part of data already registered.
A memory space of 2M bits (256K bytes) is reserved for logos and bit images. More than one logo or bit
image can be registered within this capacity limit.
* The memory spaces are cleared (space characters for user-defined fonts) by default.
