Digital Input and Digital Output for External Alarm
The Industrial Managed Switch supports Digital Input and Digital Output on its upper panel. The external alarm enables users to
use Digital Input to detect external device's 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 Industrial Managed Switch port is link-down, link-up or
power-dead.
