Chapter 6 Short Message Service Operation
The ACiC supports a Short Messaging Service (SMS Text Message) based Supervisory Control and Data
Acquisition (SCADA). SCADA via SMS is requires nothing more than a common cellular phone to perform real
time data collection and remote control.
SMS messages can be sent to one or more ACiC devices from nearly anywhere in the United States and
Canada and within approximately 15 seconds and a response to this message will be sent back to the user.
Messages can be a simple request for data and/or commands to perform some action. The ACiC can also
originate status or alarm messages per a user specified configuration.
With the SMS system the user does not require a wireless infrastructure or back
office system. There are no internet connections, databases, data viewers,
parsers, or other special hardware required. Any user with a cellular mobile
phone and proper security clearance can contact a remote ACIC to perform
SCADA operations.
6.1 Security
The ACiC provides two methods to ensure only authorized personnel may access data and send commands.
MDN Filtering: The system will limit access via SMS to ACiC controllers by allowing only a pre-specified cellular phone
number also known as a Mobile Directory Number or MDN. Up to ten MDNs can be entered using the iCConnect
software. Each MDN can be setup for one of two levels of service; 1: Data acquisition only or 2: Supervisory Control and
Data Acquisition.
Security Code: A 6 character security code may also be enabled and used with or without MDN Filtering. Users must
enter the security code within an SMS command. When the remote unit receives an incoming message with a valid
security code, the associated MDN is added to a safe senders list. MDN’s on the safe senders list expire after a period
of 5 minutes, after which an SMS with a valid security code will be required to renew the MDN as a safe sender. Valid
security codes contain only alphanumeric characters. The default security code is 654321.
Step 1: User Initiates SMS with Security Code “654321”

Using iCConnect, MDN Filtering and/or security codes can be enabled or disabled. The default state for both
MDN Filtering and Security Codes will be DISABLED. The ACiC will auto-reply to incoming messages from invalid
MDNs and/or security codes with a “Not Authorized” message. The last 64 MDNs and issued commands for all
incoming SMS messages will be logged.
