CENTURION SYSTEMS G-SWITCH-22 Programming Manual

Special Functionality The G-SWITCH-22 offers various advanced and useful features which can be easily set up via SMS or using the G-WEB online user interface. These features are intended to enhance the Module’s capabilities and offer the user more flexibility in applying the Module as a full monitoring and control solution. Below appears a list of the G-SWITCH’s advanced features as well as a definition of each. & Sticky Latches: The Module’s Outputs can be configured to ‘remember’ their state between power cycles. For instance, if Output 2 was active, i.e. the relay in an energised state, and the power is removed, when power is reapplied Output 2 will return to the activated state. This functionality is referred to as a ‘sticky latch’ and can be enabled or disabled. Sticky latches don’t apply to pulsed Outputs and are enabled by default & Filter Time: Filter Time determines how long an Input event (rising or falling edge) must be present before it is recognised, i.e. an SMS is sent. The time is set in increments of one second and the default is 0 & Blanking Time: Blanking Time determines how long the unit will wait between events before it will recognise the next event & Event Count: This refers to how many Input events must occur before it is recognised and an SMS notification is sent to users & All Pass Mode: When enabled, this useful mode allows any number that gives the Module a Missed Call to activate the Outputs, irrespective of whether they are learned into memory. A typical application would be an event such as a wedding where many guests need to be given temporary access. Instead of manually learning in a 100 guests and then having to delete them again after the occasion, the administrator can simply enable All Pass Mode and disable it again afterwards & Permitted The G-SWITCH-22 allows for time-periods to be Access Mode specified during which a specific user's phone (Recurring number will be valid and will be allowed to activate Weekly) the unit's outputs via Missed Call or SMS. Any activation from the user initiated outside of the specified time-period will be ignored. For instance, a user can be granted access between 8:00 and 17:00, Monday to Friday and his access barred from activating the outputs after hours and during weekends & Permitted In this mode, an administrator can specify two Access Mode time-based parameters between which a number (Once off) will be valid. This is ideal for guesthouse and Bed and Breakfast owners, as it enables them to set specific arrival and departure dates and times and allow access to guests based on these time-dependent limits. This feature and only be activated via G-Web Multi-user Capability (1200 phone numbers) It is important to note that the memory of the G-SWITCH-22 2G GSM Module is limited to 1200 authorised phone numbers. In other words, a maximum of 1200 phone numbers can be registered on the system at any one time. Each phone number can be configured uniquely with respect to Inputs and Outputs, as well as activation and notification messages. Each phone number can also be assigned a limited number of uses for each Output. When the memory limit is reached, trying to add new phone numbers will not overwrite or affect the existing numbers stored into the system, it will just not be possible to add the additional numbers. 3. Command Structure Programming commands are sent to the Module using a standard text message (SMS). The command structure must always take the following form: p.xxxx.command1.parameter1.parameter2 command2. parameter1.parameter2, etc. 2. In a Hurry? To simply add a phone number to the Module to trigger Output 1, with the default pulse time activated through a Missed Call, send the following SMS to the Module: p.xxxx.ap.yyyyyyyyyy, where xxxx is the system password (default is 1234¹), and yyyyyyyyyy is the phone number you wish to add. 1. For your own security, it is recommended that the default password be changed and that the SIM PIN code protection is enabled once the unit has been configured. (see CO. ‘Configuring the Module’) Record system password here Record new SIM PIN here Ensure that a record of your system password is kept in a safe place. Ensure that a record of the new SIM PIN number is kept in a safe place.

Command Overview Parameters Four-digit password (Password) System password P Description If you add a ‘space’ and then the text ‘ACK’ to the end of any command, you will receive an SMS back confirming that the command has been received by the Module. For example, p.xxxx.DP.0841234567 ACK (Airtime) Loads or queries airtime ACK

Command Description p.xxxx.CO.NP. yyyy yyyy is the new password Reset to the Factory Default Settings In the event that you forget the system password you will need to reset the Module to the Factory Default settings. To do this, please follow the steps below: 1. Power down the Module. 2. Bridge the following terminals: IN1, IN2 and GND. 3. Short out the defaulting pads by touching across them with the tip of a screwdriver. 4. Power up the Module. 5. Remove the bridges to the terminals as mentioned in point 2 and 3 above, as well as the defaulting pads. 6. The Module will now be reset to the Factory Default settings. STR. Programming Input and Output Text Strings The system allows the user to pre-program up to 20 text messages (of 25 characters each); the user can then associate messages with specific actions such as the activation of an Output or as an Input notification message. Each message is assigned a number, between 1 and 20, by the user and when an Input is configured to send notifications, or an Output configured to be activated via SMS, the user must specify what message number that Input/Output will use. To configure text strings for Output activation and Input notification, send the following command to the Module: p.xxxx.CO.STR.y.‘‘text string’’, where ‘xxxx’ represents the password and ‘y’ represents the memory slot – between 1 and 20 – to which the text string should be assigned in the system’s memory. The text between the double inverted commas is the command that will be sent to the Module in order to activate an Output, or the text that will appear on the user’s mobile phone screen when the associated Input is activated. Text strings are allocated to specific Outputs or Inputs by means of the following command structure: p.xxxx.AP.phone number.OUz.‘‘y’’.INz.‘‘y’’. In this instance, ‘‘xxxx’’ again represents the password, ‘‘z’’ is the number of the Input/Output to which one wishes to assign a text string, and ‘‘y’’ is the text string slot in the system’s memory. Examples & p.xxxx.CO.STR.1.‘‘pump active’’ This command will configure text string ‘‘1'’ as ‘‘pump active’’. & p.xxxx.CO.STR.5.‘‘tan'k full’’.STR.6.‘‘tank empty’’ Configures text string 5 as ‘‘tank full’’ and text string 6 as ‘‘tank empty’’. & P.xxxx.CO.STR.3.‘‘Open gate’’ This command configures text string 3 as ‘‘Open gate’’. The ‘‘Open gate’’ command would be used to activate an output, the next example illustrates this. & p.xxxx.AP.0821234596.OU1.‘‘3’’ Adds phone number 0821234596 to the system and enables Output 1 to be activated by an SMS. To activate the Output, either SMS the text stored in memory location 3 to the Module, or use the Output activation command p.xxxx.OU.OU1on All of the information on the Module will be erased.

Adding a Phone This command allows new phone numbers to be added to the system. When adding a new phone, it is possible to specify which Outputs are to be activated by a Missed Call from the phone, and which Inputs will cause a message to be sent to the phone. The number of times the phone can be used to activate the system can also be specified. Examples (Commands have been highlighted for clarity) p.xxxx.AP.0841 234567.OU2 Adds phone number 0841234567 to the system, and assigns Output 2 to be activated by a Missed Call from this number. Command Description p.xxxx.AP.0841 234567 Adds phone number 0841234567 to the system and, since no parameters are specified, by default assigns Output 1 to be activated by a Missed Call from this number. This allows easy addition of new phones to a basic system. For your convenience, a template has been provided below which can be used to note down which text strings have been associated with which number in the system’s memory. It is also possible to query the Module as to which messages are saved in its memory by sending the following command: p.xxxx.co.lm, where ‘‘xxxx’’ represents the system password. & p.xxxx.AP.0823359981.OU2.‘‘10’’.IN1R.‘‘3’’.IN1F.‘‘4’’ Adds phone number 0823359981 to the system and configures Output 2 to be activated by text string 10, Input 1 to send an SMS with text string 3 on rising edge activation and the same Input to send an SMS with text string 4 on falling edge activation. In such a case, text string 3 would typically be something like ‘‘power off’’ and text string 4 could be ‘‘power back on’’. p.xxxx.AP.0841 234567.OU1. OU2 Adds phone number 0841234567 to the system, and assigns both Output 1 and Output 2 to be activated by a Missed Call from this number. p.xxxx.AP.0841 234567.083765 4321.OU1 Adds phone numbers 0841234567 and 0837654321 to the system, and assigns Output 1 to be activated by a Missed Call from either of these numbers.

Query controller status/settings Command Description p.xxxx.CO.QS Sends an SMS to the querying phone with the following information: & Current state of the Outputs & Current state of the Inputs & Output configuration (Pulsed/Latched) & Output pulse times & Input-Output mappings & IP address and port of host server E. Mapping Inputs to Outputs F. Clearing Memory p.xxxx.CO.IO. Allows activation and deactivation of Input-Output mappings. If an Input is mapped to an Output, and that Input is activated, the mapped Output will also activate, responding according to its configuration settings: IN1OU1: Maps Input 1 to Output 1 IN1OU2: Maps Input 1 to Output 2 IN2OU1: Maps Input 2 to Output 1 IN2OU2: Maps Input 2 to Output 2 DIN1OU1: Deletes Input 1 to Output 1 mapping DIN1OU2: Deletes Input 1 to Output 2 mapping DIN2OU1: Deletes Input 2 to Output 1 mapping DIN2OU2: Deletes Input 2 to Output 2 mapping Even though a preconfigured SMS text may have been assigned to Outputs when adding a phone to the system, the Outputs on the Module can also be explicitly activated by sending an SMS to the Module. For added convenience and flexibility, the system does allow numbers that have not been learned into memory to activate Outputs via SMS; however, this functionality is password- protected and the owner of the originating number will have to be in possession of the system password in order to activate Outputs in this manner. Outputs can be activated with one of the commands below: & OU.OU1on Output command --- Output 1 on & OU.OU2on Output command --- Output 2 on & OU.OU1off Output command --- Output 1 off & OU.OU2off Output command --- Output 2 off & OU.OU1on2off Output command --- Output 1 on and 2 off & OU.OU2on1off Output command --- Output 2 on and 1 off & OU.allon Output command --- both Outputs on & OU.alloff Output command --- both Outputs off Example & p.1234.OU.OU2ON Switches Output 2 on G.
