9.1.4 DEFINITION OF COMMAND
Single function command
It is a command that a command alone will complete an operation, and the command section consists of three characters.
Adjustment command and adjustment value
It is a command, accompanied by an adjustment value, to change the parameter value, and the command section is also three characters
as in the case of a single function command. The adjustment value is a three character decimal numerical data within the range of 000-999.
Incidentally, the adjustable range will be different depending on the function to be adjusted. (Be careful as it is not always up to 999.)
∗ XXX will be transmitted if the received command is exceeding the adjustable range of the adjustment value.
∗ When the same setting value is transmitted consecutively for two times or more, the setting is overwritten without responding
with XXX even though the command is invalid, and an ACK after deleting the ID is sent back.
Setting command and setting value
It is a command, accompanied by a setting value, to change the setting value of the parameter, and the command section
consists of three characters. The setting value consists of three characters, and the first character is fixed to S and the
remaining two characters are decimal numbers within the range of S00-S99.
∗ XXX will be transmitted if the received command does not exist as a setting value.
∗ When the same setting value is transmitted consecutively for two times or more, the setting is overwritten without
responding with XXX even though the command is invalid, and an ACK after deleting the ID is sent back.
Status acquisition (QUEST) command
This is a command to report the operational status and the setting value to the system side.
When a command is received from the system side, an applicable content depending on the type of command is read out
from the memory and sent back.
The command section consists of three characters, and the first character is fixed to Q. The second character and on are
set depending on the content of the information.
When sending back a reply data, the received command, various data converted to ASCII code and checksum of that data are
added and sent.
The data length will be subject to each individual specification as the content of a reply will be different depending on the
type of QUEST command.
