noise is heard
If REAC devices are connected incorrectly or if the REAC mode
setting is incorrect, it will not be possible to input from REAC, and
noise may be heard.
In this case, first check the connections between the M-200i and
the input/output units.
●

correct REAC port
●
Make sure that the REAC mode of the input/output units is
correct
