 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 r

emote register.

Data number: Write the data number of the parameter to be written, by referring to "Command

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 "Command

Parameter List" (p

age 3-24).

(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 "Command

respons

e list" (page 3-8).

(9) When the "request for command" is set to 0, the "command completed" and "command error"

parameters flip to 0.
