[Command procedure]
Commands are sent using the following procedure. Confirm that the controller batch setting is ON.
 Start high-speed data communication
When the start high-speed data communication command is sent to the controller profile data measured
on LJ-V starts to be output.
* When the batch setting is ON, trigger input cannot be received until batch measuring starts.
For this reason, profiles are not output even if the start high-speed data communication command in
step 1 is sent.
