Version Information Output Command
This command outputs the version information of the control pro-
gram stored in the boot area. Execute the version information output
command as explained here following.
Download Command
This command downloads a program to the RAM for execution. Ex-
ecute the download command as explained here following.
(1) Transfer the
FA
16
command code with the 1st byte.
(2) Transfer the program size with the 2nd and 3rd bytes.
(3) Transfer the check sum with the 4th byte. The check sum is
added to all data sent with the 5th byte onward.
(4) The program to execute is sent with the 5th byte onward.
When all data has been transmitted, if the check sum matches, the
downloaded program is executed. The size of the program will vary
according to the internal RAM.

(1) Transfer the
FB
16
command code with the 1st byte.
(2) The version information will be output from the 2nd byte onward.
This data is composed of 8 ASCII code characters.
