Remote Call Input
Any change in the Remote Call Input jacks (one for
each channel) will be detected by the IDA-4 Plus. For
voltage output remote call, connect the higher potential
to the ring and the lower potential or ground to the tip.
For relay output remote call, the polarity does not
matter. (Refer to the pump manufacturer's service
from pump
manual when preparing a remote-call input cable).
