Settings&Operation
***Strongly Recommend using the APP to program it***
Notice:
- The default Password is 1234.
- The unit cannot support PIN Code Protected SIM Card
- You can program the unit with SMS commands using your phone.
- Remember that commands must be CAPITAL LETTERS. It is PWD not pwd, CAP not Cap, etc. Don’t add spaces or any other character.
- The PWD in the commands is means the password, when you use it, please a stand it by the digital number; the capital letter PWD is the command letter, use PWD directly.
- Some GSM/3G operators use different SMS parameters; the units can’t return the SMS confirmation in some gsm operators, but it can perform the functions correctly. Also, you can try to add the country code before the number, see the below settings:
For example:
E.g.: the country code is 0086, or +86.
The user cell phone number is 13600000000 and has been assigned as a SMS Alert number, the sim card number in the panel is 13512345678.
When you set up the number as the authorized number, please setup as 008613600000000 or +86136000000000. Not 13600000000. - If the password is correct but the command is incorrect, the RTU502x will return: SMS Format Error, Please check Caps Lock in Command! So please check the Command, or add the country code before the telephone number or check the input is in ENGLISH INPUT METHOD and CAPS LOCK. If password incorrect then will not any response SMS.
- Once the GSM/3G Unit received the SMS Command, will return SMS to confirmation, if no SMS return, please check your command or resend again.
- The SMS commands that you will certainly use in the GSM units are the following:
