How to set the SMS module of Haikang alarm host?

1. Connect the alarm to the interface of computer 232, plug in the power supply, and insert the mobile phone card into the alarm module. Be careful not to use the telecom mobile phone card. It is best to use an old mobile phone card, which has a large chip area and is well connected to the machine. Put the mobile phone card into Cato and insert it into the card slot face down. Observe the light next to the card slot. If it flashes every 2-3 seconds, it means it is normal. If the light flashes abnormally, please pull out the mobile phone card and insert it again. Or use another mobile phone to dial the mobile phone card inserted in the card slot. If it is a normal waiting sound, it means that the mobile phone card is plugged in. On the other hand, if the prompt "The number you dialed is power off", it means that the mobile phone card is not plugged in or the signal is not good.

2. Open the system software, click "Alarm Settings", check the alarm light in "Sound Alarm" to enable, and check "Over-standard SMS Alarm" in the column of "SMS Alarm" to fill in the retransmission interval yourself, then click "Add" to fill in the first mobile phone number to receive SMS, and then add the second and third mobile phone numbers to receive SMS.

3. After the above contents are set, you'd better test them first. If a monitoring point does not send a short message after the temperature or humidity exceeds the standard, restart the computer and try again. If you still can't receive the alarm message, please check the COM port settings of the information module.

After the installation and setting of the above steps, the alarm module can work normally.
