Precautions for trouble-free operation
For a 1:N connection involving a link unit, it is necessary to add an normal controlled RS signal from an
upstream controller to a CS signal. The RS signal must be turned OFF within 15 msec after completion of
data transmission. Otherwise, this configuration does not operate correctly.
