Digital Input/Output (GE-DSH-73)

The 7 10/100TX + 3 10/100/1000T/100/1000 SFP Combo w/ X-Ring L2 Managed
Industrial Switch contains two digital inputs and two digital outputs. The digital inputs
may be used to receive the voltage-changing signal of the remote equipment to
sense the state of the remote equipment like heater, pump, and other electrical
equipment. Therefore the switch can be configured to send system log, SMTP and
SNMP traps to syslog server, SMTP server and SNMP trap station respectively (please
refer to System Event Log and SNMP configuration section). Outputs are open-
collector transistor switches used to connect to the external device like alarm buzzer
or LED to inform the user of the port/power status.
