GD-04 "David" GSM communicator
The GD-04 DAVID is a universal GSM dialer and controller. Provides 2 power relays and 4 input terminals. Configuration web page.
DAViD provides:
- 2 output contacts of power relays X and Y (each allows up to 5A/250V)
- 4 input terminals A to D for SMS reporting (the inputs react to a connection or disconnection to or from a common GND terminal)
David can be used as:
- A switch with SMS remote control. SMS texts for switching particular terminals on/off are configurable.
- 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 latch control etc.
- A relay with validity-limited dialling-in remote control. Each authorized number can have a limit to the number of calls. When the call count reaches the limit the tel. number is de-authorized. This can be useful for pre-paid services such as e.g. parking. Any tel. number can be re-authorized via SMS by the administrator.
- An SMS reporter. Input A to D activations or deactivations can be reported by SMS and optionally confirmed by phone calls. Each input can have its own message texts and up to 8 tel. numbers programmed.

Specifications
 |
A GD-04A back-up module, which provides David with the ability to work approx. 12 to 24 hours continually without an external power supply
|
 |
A GD-04D DTMF module, which allows you to control David’s output relays by entering numeric codes (DTMF codes) on the telephone keypad during calls
|
 |
A GD-04P link cable, which allows you to connect David to a PC through a USB port and perform any desired configuration using GDLink software.
|
 |
A GD-04R radio module, which allows input A to D activations via wireless buttons or detectors of the OASiS series and also provides David with the capability of output relay X or Y state transmission to UC or AC OASiS receivers. In addition, you can control relays X or Y "locally" via RC-8x keyfobs (so that an appliance can be controlled both via a mobile phone and a keyfob). The module also allows heating control (again locally or remotely via a mobile phone) using wireless thermostats of the TP-8x series.
