23.2 Writing with Flash Programmer
Data can be written to the flash memory on-board or off-board, by using a dedicated flash programmer.
(1) On-board programming
The contents of the flash memory can be rewritten after the
system. The connectors that connect the dedicated flash programmer must be mounted on the target system.
(2) Off-board programming
Data can be written to the flash memory with a dedicated program adapter (FA series) before the
mounted on the target system.
Remark The FA series is a product of Naito Densei Machida Mfg. Co., Ltd.
