up voltage) after adding external pull-up resistor; the output signal becomes low level
when there is alarm output.
The operating current of alarm output port is recommended to be less than 10mA.
The max current which is used to drive external circuit is 80mA, it is recommended to add
relay externally when it is beyond the value.
Step 3 Log in web interface, and configure alarm input and alarm output in alarm setting.
The alarm input in the web interface is corresponding to the alarm input end of the
I/O port. There will be high level and low level alarm signal generated by the alarm input
device when alarm occurs, set the input mode to "NO" (default) if the alarm input signal
is logic "0" and to "NC" if the alarm input signal is logic "1".
The alarm output in the web interface is corresponding to the alarm output end of
the device, which is also alarm output end of the I/O port.
