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.
