Alarm
The alarm interface is shown as in Figure 2-3. Please follow the steps listed below for local alarm input
and output connection.
1) Connect the alarm input device to the alarm input port of the I/O cable.
2) Connect the alarm output device to the alarm output port of I/O cable. Alarm output port is open
collector output which requires pull-up resistor of 10k to 3.3V eternally.
3) Open the Web, go to the Figure 2-3. Set alarm input and output correspondingly. Alarm input on
WEB corresponds to I/O cable on device. When there is alarm, alarm input device will generate signal
of high and low level. Set corresponding NO and NC inputs.
4) Set the WEB alarm output. The alarm output s for the alarm output port of the device. It is the alarm
output port of the I/O cable.
Figure 2-3 Alarm
Please refer to the following figure for alarm input information. See Figure 2-4.
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 the 5V or is idle, the device collects the
logic “1”. When the input signal is grounded, the device collects the logic “0”.
