Writing settings or status
(1) To see that the sensor amplifier is ready to send/receive commands, check that the "sensor ready"
parameter is set to 1.
(2) Write the data category and command number in the remote register.
Data category: In the high byte, write the data category of the parameter to be written, by referring
to
"Command Parameter List" (page 3-24).
Data number: For writing, write 01h in the low byte.
(3) Write the data number in the remote register.
Data number: Write the data number of the parameter to be written, by referring to
Parameter List" (page 3-24).
ID number: For data category 00/10, write the ID number of the sensor amplifier, to which the param-
eter is written, in the high byte.
(4) In the remote register, write the data to be written. For details of writable ranges, see
(5) Execute the command by activating the "request for command" (0 -> 1).
(6) After the command execution completes, the "command completed" signal flips from 0 to 1.
(7) If an error occurs during command execution, the "command error" signal flips from 0 to 1. For
details of the error, check the values entered in the "command response".
(8) Details of the command execution result are stored. For details of the result, see
(9) When the "request for command" is set to 0, the "command completed" and "command error"
