Digital input/output
Digital input allows a user to log an external device (such as an industrial cooler) as
dead or alive, or something else. The system will log a user customized message into
system log and syslog, and issue SNMP trap or an alarm email.
Digital Output allows a user to monitor the switch port and power, and allows the
system to issue a high or low signal to an external device (such as an alarm) when the
monitor port or power has failed.
