Operation
Switching Outputs from your Phone Two output terminals (X or Y) can be used as: An SMS-controlled switch. SMS texts for switching particular terminals on/off are configurable (e.g. "light on", "light off" and "sunblind close", "sunblind open"). Any such instruction can be automatically echoed by David sending you an SMS report. A time-switch which can be activated remotely via a mobile phone. (the switch-on period is configurable from 1 second to 10 hours). A relay with dialling-in remote control. Up to 50 tel. numbers can be authorized for each relay. Because calls are not answered dialling-in control within GSM is free of charge. (David only checks the caller’s number and – if the number is authorized – responds with relay activation.) This can be used for parking access control, door lock control, switching lights etc. Each authorized number can have a limit to the number of calls. For example, when the customer is only allowed to open the parking lot entrance for 30 times at most, any further access is denied to him/her. The customer can then be re-authorized for entrance control via SMS by the administrator.   Reporting Inputs to your phone Four input terminals (A to D) can have their switching on/off reported by SMS (e.g. "freezer mains dropout" or "freezer mains recovered") SMS reports can contain up to 30 characters. Each input can have up to 8 tel. numbers programmed for where reports are sent to. SMS reports can be emphasized by subsequent calls. David’s current status (input/output terminal states) can be interrogated remotely via SMS instructions. David can perform periodical calls every 24 hours allowing you to monitor its functioning. If you use a prepaid SIM card, David can send you a warning SMS whenever a critically low credit balance is detected on periodic interrogation.   Configuring DAVID is easy and can be done through sending SMS messages (see the user manual), via the optional software and CD or via a simple web interface. Fill in the web form, and the settings are automatically sent to your DAVID
