5. Insert the circuit board back to its position.
6. Do the wiring, see below.
4. Wiring
1. Power supply – use the +12V and GND terminals (grey
colour = +12V). Any power supply adapter used should
provide 12V DC voltage and up to 500mA of current. Do
not turn the power supply on until all input / output wiring
has been done.
2. Output relay contacts – available
at the X1+X2 and Y1+Y2 terminals.
Each contact is fused to 5A. The
circuits which the contacts belong to
are protected from the remaining
electronics by a safety separator
and are capable of switching up to
2.5A at 250V AC. The following
example shows a light bulb control via the Y output relay:
3. Input terminals – marked A to D. The terminals respond to a
connection or disconnection to or from GND by sending an SMS
report. No external voltage supply can be connected to these
terminals – they can only be controlled via a potential-free
switch/contact. Example of wiring a switch to input A:
5. Initial powering up
1. Turn the power supply on, registering to the GSM network is indicated by the LED
flashing (if no indication occurs, check the power supply wiring).
2. After GSM registration the LED stops flashing (usually within 1 minute). Continued
flashing indicates a GSM registration fault. Disconnect the power supply and check that a
valid SIM card has been correctly installed into the device, see 2 and 3).
3. Send the SMS instruction STATUS to David’s SIM card number.
4. David responds by a status report,e.g. STATUS: A0,B0,C0,D0,X0,Y0,GSM:80%,
Vcc:12.2V (which means that all A to D inputs and both the X and Y relays are switched off,
the GSM signal strength is 80% and the power supply voltage is 12.2V). Depending on the
GSM network traffic the response may take some time. If no response occurs, verify that
“STATUS” is spelt exactly right in the text of the message and that you are sending the
message to David’s correct SIM card number (repeat the previous step).
6. Programming
6.1. Via the Internet
The simplest way to program David is via the web site www.david.jablotron.cz.
You fill in all the required parameters in a form on a single web page, press the Send button,
and the Jablotron web server will forward the settings to your David via the GSM network.
Performance of a successful transfer is confirmed from David by an SMS reply "PROGRAM OK"
to your mobile phone.
