• New Password

  Change the current password with a new one. If this field is empty, it means no need to change the password.

  Note: In particular, it always will be empty when reading this field.

• Device Name

  The name of the terminal device. If this field is empty, it means no need to change the device name.

• SMS Command Number Limit

  Specify whether the terminal needs to limit the SMS senders when receiving @Track commands via SMS.

  • 0 - No limit. No matter from which number the short message is received, it will be processed.
