Operation description of GET command
Conditions under which GET commands are enabled
Most of the GET commands are enabled at any time, regardless of unit's being on/off or in Factory or Normal mode. However, some GET
commands must be issued while the power is on to acquire correct data.
[Operations]
• Reading out and sending various data stored in the EEPROMs and the RAMs of microcomputers
• Adding a received string of command characters at the beginning of reply data as an echoback
• Decimal notation are converted into ASCII numerics and transmitted.
• CS is 2 bytes, to be interpreted as ASCII codes for 2 hexadecimal digits. These are the low-order 2 bytes of the total value of "receive
command + transmission data" (except STX and ETX).
