The IVR-300/IVR-300W supports Digital Input and Digital Output on its upper panel. This external alarm
enables users to use Digital Input to detect and log external device status (such as door intrusion detector),
and send event alarm to the administrators. The Digital Output could be used to alarm the administrators if the
IVR-300/IVR-300W port shows link down, link up or power failure.
This page provides Digital Input / Output setting as shown below.
