Alarm input, output description:
Step 1 Step 1 Connect alarm input device to the alarm input Connect alarm input device to the alarm input port.
Step 2 Step 2 Connect alarm output device to the alarm output Connect alarm output device to the alarm output port. Alarm output is collector open circuit output
which connects 10K resistor to 3.3V externally.
Step 3 Open the web viewer, set alarm input and output correspondingly.
Please refer to the following figure for alarm input information. See Figure Please refer to the following figure for alarm input information. See Figure 1-4.
Alarm input: When the input signal is idle or grounded, the device Alarm input: When the input signal is idle or grounded, the device can collect the different statuses of the
alarm input port. When the input signal is connected to 3.3V or alarm input port. When the input signal is connected to 3.3V or is idle, the device collects the logic "1". When
the input signal is grounded, the device collects the logic "0". the input signal is grounded, the device collects the logic "0".
