GD-04 DAVID 1 MKS51203
The GD-04 “David” GSM communicator
User manual
The GD-04 module got its name from David, a biblical king who outsmarted Goliath, a giant. In our
case, Goliath is meant to be the GSM network. We hope that the skills of your tiny David will help you
manage the giant.
1. Basic description

SIM card
Output fuses
1.1. 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)
GD-04 DAVID 2 MKS51203
1.2. 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 deauthorized. 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.
• Examples of David applications can be found on http://www.jablotron.cz/david/en/examples.htm
1.3. David can be supplemented with:
• 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, (see 11.1).
• 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, (see 11.2).
• 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 (see 11.4).
• 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 (see 11.3).
A detailed description of optional accessories can be found in chapter 11.
2. David’s SIM card
• In order to function, David needs a SIM card, preferably a tariffed one.
• Test the SIM card by using it in your mobile phone – SMS sending and calling must work
correctly.
• Switch off the PIN code protection via the phone menu (or set the PIN code to 1234).
• Check the GSM signal strength in David’s location.
3. Installation
1. The GSM antenna should not be shielded by metals. If necessary, an external antenna
designed for the 900/1800MHz GSM band can be connected via a 50Ω SMA connector.
2. Open the cover and release the electronic circuit board by pressing the tabs.
3. Mount the rear plastic cover at the desired location.
4. Insert a SIM card: Open the SIM card case by shifting the moving part in the direction of
the terminals and tipping it off. Make sure that the card is correctly oriented and insert it.
Close the SIM card case (fold and re-shift the moving part).

JABLOTRON ALARMS a.s. hereby declares that this product
is in compliance with the essential requirements and other
relevant provisions of Directive 1999/5/EC. The original of
the conformity assessment can be found on the web site
www.jablotron.com, Technical Support section.
Note: Although this product does not contain any harmful
materials we suggest you return the product to the dealer or
directly to the manufacturer after use.
GD-04 DAVID 3 MKS51203
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.

GD-04 DAVID 4 MKS51203
All parameters are sufficiently described on the page so that you do not need to use David’s
installation or user manual to perform programming.
Programming via the web site is free of charge. No user registration is required. Your David’s
settings are not stored on the web server. Instead, you can save them as a file in your computer
for future use (the file can then be imported to the page). The page does not allow you to
retrieve the current settings of your David. Any programming is only possible if a valid access
code (default = PC) is specified (the code, being a part of David’s settings, is not stored on the
web server, only in your David). This makes the web access to your David both secure and
simple.
6.2. Using a PC running GDLink software
If you need to program David frequently, connecting David to a PC running specialized
software is the recommended option. GDLink software allows you not only to send programming
instructions but also to retrieve the current David settings. For the PC connection, you can use a
GD-04P link cable connected to a USB port (the cable is supplied separately). GDLink software
is available either in the GD-04P’s package or on the www.jablotron.com
web site.
6.3. SMS instructions
David can also be configured via SMS instructions from your mobile phone. The programming
instruction format is explained in the following example:
PC, ARX, heating on, DRX, heating off
where:
PC is the access (programming) code, required at the start of any programming
SMS message* (2 to 8 ASCII characters, the factory default setting is PC)
, is a comma separator
ARX is the name of the instruction for programming the text you wish to use for
switching relay X on via SMS. The desired text (“heating on”) follows, separated
by a comma.
DRX is similar to ARX, related to switching relay X off.
The above SMS instruction tells David that the X relay can be switched on/off by the SMS
instructions “heating on” / ”heating off”.
Note:
This text distinguishes between SMS messages and SMS instructions – an SMS message
can contain multiple SMS instructions in a sequence.
SMS instruction rules:
1. Any programming SMS message must start with a valid access code (the factory default
code is PC). Multiple messages mean multiple codes.
2. A single message can contain multiple instructions. David is capable of long message
processing – if enabled by your phone, you can write and send a programming SMS
message containing up to 2400 ASCII characters.
3. The comma separator is used both between individual instructions and between individual
segments within instructions.
4. Spaces are ignored, except in operational texts which are meant to be a part of a David
setting.
5. The successful processing of a programming SMS is confirmed from David by the SMS
reply “PROGRAM OK”.
6. When an error is encountered, David reports a “PROGRAM ERROR” followed by the text of
the instruction which has not been recognized. Preceding instructions within the message
are carried out, succeeding instructions are ignored.
7. David is not case sensitive (does not distinguish between lowercase and UPPERCASE
letters).
GD-04 DAVID 9 MKS51203
• Normally, an A- or B- enrolled thermostat switches the heating (via the X or Y relay) so that
temperature comfort is maintained. However, you can put the heating in economic mode
by sending an SMS instruction for switching relay X or Y on, which puts the heating back to
normal mode. The same can be done by connecting the A or B input to GND. The thermostat
will then only provide anti-freeze protection: the heating will be switched on when a critically
low temperature is signalled (e.g. 6°C). Sending an SMS instruction for switching relay X or Y
off puts the heating back to normal mode (with A or B disconnected from GND).
• If input A or B is used for thermostat enrollment, the status SMS report (obtained from David
on an SMS request) contains information about the temperature.
Example: STATUS:A0,B0,C0,D0,X1,Y0,GSM:70%,TA:25/24C,TB:22/22C, Vcc:12.2V
where: TA labels data from thermostat A, TB labels data from thermostat B. The data is of
the form maintained temperature / measured temperature.
• Enrolling a thermostat to the A or B input disables relay X or Y enrollments.
• DIP switch g setting has no effect on enrolled thermostat operation.
To delete all enrolled items, press and hold buttons XY and ABCD until two long flashes
occur on the red LED.
11.4. The GD-04P link cable
The GD-04P cable allows you to link David with a PC through an USB port and perform any
desired configuration using GDLink software. The software is supplied on a CD in the package
together with all the necessary drivers. You can also download GDLink from
www.jablotron.com
.
11.4.5. Installing GDLink and the drivers
1. Connect the GD-04P cable to a free USB port on your PC and insert the CD into the CD drive.
2. Wait for “New Hardware Wizard“ to start up.
3. Search for the drivers on the removable medium (CD).
4. When installing for WIN XP, ignore the notification about wrong authenticity with WIN XP and
continue with the installation process. Leave the other parameters without any modifications.
5. Finish the new hardware installation wizard process.
6. There are two devices contained in one, so please wait for the “New hardware wizard” to start
again. Repeat the procedure according to steps 3 to 5.
7. Your PC now has two new devices after successful installation - "Jablotron serial interface" as
a serial port (COM) driver and the USB device with the same name as the driver for USB.
8. Install the GDLink software on your PC.
9. Connect the GD-04P cable into David’s digital bus connector. GDLink is now ready to be started.
11.4.6. Using GDLink
• The program allows for:
o Retrieval and modification of
David settings.
o Displaying the last 127 memorized
events.
o Relays X and Y direct control.
o Inputs A to D status display.
• A comprehensible help option is
provided as a part of the program.
GD-04 DAVID 8 MKS51203
responded to by an SMS report about input activation (a connection to GND). Pressing the B
button is responded to by an SMS report about input deactivation (a disconnection from GND).
• For single-button controls (such as the RC-87 or RC-89), pressing the button is responded to
by an SMS report about input activation.
• Enrolled JA-8x detectors work with the following logic:
o Input activation is reported by SMS in response to detector triggering (body movement,
door opening, breaking glass, fire, tamper...)
o Input deactivation is reported by SMS in response to panic signals or to the de-triggering
of state-providing detectors (JA-8xM)
• Wireless devices can also be assigned by entering their production code using the LRN
instruction.
• An input terminal with a wireless device assigned to it can be configured (see Optional functions,
DIP parameter g) so that connection to GND disables the reception of wireless signals. This
feature allows the setting/unsetting of enrolled detectors.
11.3.3. Controlling the outputs using an RC-8x wireless button unit
Each X or Y output
can have four OASiS wireless button units assigned to it.
1. Press and hold the XY button on the GD-04R module
2. Entering enrollment mode is indicated after 5 seconds by flashing of the LED on the
GD-04R module – release the button.
3. Enroll up to 4 wireless button units to the X output (send enrollment signals to the
module). Press the XY button again to allow enrolling to the Y output. A change of
flashing rate indicates this. Wireless button units are enrolled by pressing them.
Enrollment is confirmed by a long flash of the LED on the GD-04R. Important: Enrolling
the first device erases all the previously enrolled devices. Thus all the desired
devices should be enrolled in a single enrollment session.
4. Exit enrollment mode by pressing the XY button (enrollment is automatically terminated
after the fourth device has been assigned or after 40 seconds).
5. After enrollment mode termination, the LED on the module lights for approx. 5 seconds to
indicate enrollment data storage.
6. It is possible to enroll a wireless button unit with two buttons by pressing any button(s)
(A, B or A+B). Button A switches on an output, button B switches off an output and A+B
changes (toggles) the status of an output (switch on – switch off). A wireless button unit
with one button (RC-87 or RC-89), changes the status of an output (switch on – switch
off).
To delete all enrolled items, press and hold buttons XY and ABCD until two long flashes
occur on the red LED.
11.3.4. Using David for heating operation and status reporting
Each input A–D can have a wireless thermostat of the TP-8x series assigned to it (see 11.3.2).
• Enroll a thermostat to any of the A, B, C or D inputs to get reports about exceeding the
maximum/minimum allowable temperature limits in your house:
o Exceeding the upper temperature limit (e.g. 60°C) is responded to by an SMS report about
input activation.
o Dropping under the lower temperature limit (e.g. 3°C) is responded to by an SMS report
about input de-activation.
• Enroll a thermostat to one of the A or B inputs to take control of the temperature in your
house. An A-assigned thermostat controls relay X, a B-assigned thermostat controls relay Y.
This way heating control is established, supplemented by the reporting described above.
Thermostats enrolled to C or D inputs only provide reporting.
GD-04 DAVID 5 MKS51203
8. The use of accented characters is not recommended.
9. After an SMS message has been received, David switches off both the X and Y relays.
10. See table 1 for a brief instruction list.
7. Remote operation via SMS instructions
When using texts which have been programmed for David SMS operation (relay control, status
interrogation) the following conditions apply:
• David does not distinguish between authorized and unauthorized phones when processing
operational SMS instructions. Instructions can be sent from any phones, but the texts must match the
texts which have been pre-programmed (except the lowercase/UPPERCASE attribute).
• Access codes are NOT part of operational SMSes.
• A single SMS message can contain multiple instructions separated by commas, e.g.
HEATING ON, LIGHTS OFF, STATUS
• David can be so configured that every instruction performance is reported by SMS.
• Received SMSes with unrecognised instructions can be forwarded to the so called service
number (see table 1).
• If you are not sure whether any other text will be automatically added to the SMS on its way to David
(for example, when using an SMS internet gate) type the message like this: %instructions%%.
Example: The SMS text “1/1 www: %heating on%%” is interpreted as heating on.
8. Remote operation via dialling-in
David allows you to control the X and Y relays via dialling-in from pre-authorised phones. If a
call is made to David from a pre-programmed number, the call is rejected and the relay reacts as
follows:
o If a limit is set to the relay switch-on period then the relay switches on for the limit period.
o If no limit is set (zero value is set for the limit) then the relay switches on permanently -
until a switch-off SMS instruction or another dialling-in event occurs.
Notes:
• Up to 50 tel. numbers can be programmed for each relay.
• Each tel. number can have a limit to the number of calls so that any further calls are ignored.
• This feature is not applicable to phones with withheld numbers.
• Dialling-in relay control can be reported by SMS.
9. Using prepaid SIM cards
Prepaid SIM cards are NOT recommended for use in David, because they increase the risk
of David malfunctioning due to a possible credit balance under-run or expiration of the time limit.
If you still decide to use a prepaid SIM card, you can configure David for periodic balance
interrogation. If the reported credit balance is lower than the set limit, the credit balance
message will be automatically sent to the service phone numbers. To program this feature you
need to know some data specific to the GSM provider (see the SIM card documentation). The
programming instruction is of the following form:
PC, CRD, xxxx, dd, hhh, pp
where:
PC is the access code
CRD is the name of the instruction for credit balance interrogation
xxxx is the command string to ascertain the credit (GSM network specific, e.g. *104#)
dd is the auto-interrogation frequency in days
hhh is the minimum acceptable credit balance
GD-04 DAVID 6 MKS51203
pp is the textual position at which the number showing the balance starts in the
reply message from the GSM provider
Example: If you require at least 50€ of credit balance, and the USSD code used to query the
available balance is *104# and you want a weekly interrogation frequency, use the following
instruction:
PC, CRD, *104*#, 7, 50, 01
If you do not want automatic interrogation, you can program David to report the balance in
response to your SMS instruction: PC, CRD . The programming is achieved by a programming
instruction according to the following example:
PC, CRD, *104*#, 0, 0, 0
Note: David’s SIM card balance interrogation may stop working due to changes in GSM
services (e.g. a different response format). You should therefore be acquainted with the
methods your GSM provider uses or will use for querying the available balance.
10. Reset to factory defaults
You can reset David to the factory default settings via the SMS instruction PC, RST, where PC
is a valid access code - see Table 1.
Another option is to use the RESET jumper (next to the SIM case):
a) Turn the power supply off (including the backup module if used).
b) Connect the RESET jumper, turn the power supply on and disconnect the jumper
after about 5s.
Note: Performing a RESET erases all programmed tel. numbers and texts.
11. Optional accessories
David’s functionality can be extended by optional modules or other separately supplied
accessories:
11.1. The GD-04A back-up module
This module is imbedded in a specially-enlarged replacement cover. Installation is performed
by replacing the original cover, together with wiring the GD-04A module to the GD-04 circuit
board via the corresponding connector.
The backup battery requires approx. 72 hours to be fully charged. The battery provides
approx. 12 to 24 hours of backup operation, depending on the output relay state and on the
GSM signal strength (as with any GSM device, David’s consumption is higher in places with a
low signal level as the transmitter power has to be increased).
Only David’s electronics is backed up. No voltage is available on the +12V terminal
during backup operation.
Discharging the battery causes David to be switched off (including the X and Y relays). After
the recovery of the main power supply David will switch on (but the relays stay switched off) and
starts charging the battery. The message POWER FAIL or POWER RECOVERY is sent to the
service number (STN).
11.2. The GD-04D DTMF module
The GD-04D allows relay X and Y control by entering numeric codes (DTMF codes) on the telephone
keypad during calls. The DTMF codes intended for use have to be programmed, see table 1.
The module can be installed by plugging in to the appropriate digital bus connector after the
power supply has been disconnected.
GD-04 DAVID 7 MKS51203
11.2.1. DTMF relay control
• Call David’s tel. number. After about 7 seconds, David responds with a beep on the line
(this means that the call has been answered) followed by relay X and Y status indication (in
this order): 2 short beeps = OFF, 1 long beep = ON.
• Enter the DTMF code. A relay switch-on is confirmed by a long beep, a switch-off by two short beeps.
• Terminate the call (David automatically terminates the call after 60 seconds).
• After the call has been terminated David reports the current relay status via SMS.
Note: Too weak a GSM signal in David’s or your location may result in DTMF control
malfunctions.
11.3. The GD-04R radio module
By plugging the GD-04R radio module into the digital bus connector (after the power supply has
been disconnected) your David acquires the following capabilities:
• Relay X and Y state transmission to UC or AC OASiS wireless
receivers.
• Input A to D activations via RC-8x OASiS wireless buttons or via JA-
8x OASiS wireless detectors.
• Relay X or Y control via RC-8x OASiS wireless buttons.
• Relay X or Y control via a TP-8x wireless thermostat.
The module has a built-in internal antenna. If necessary, a Jablotron
external antenna of type AN-80 or AN-81 can be applied to extend David’s
working range.
Note: The external antenna is always needed when the GD-04A back-up module is used.
11.3.1. Transmitting X or Y relay status to an UC-82 or AC-82 receiver
Enter mode 4 on the receiver and press the XY button on David’s GD-04R module. This
establishes a connection so that the receiver’s relay status mirrors David’s relay status. There is
no limit to the number of UC/AC receivers which can be connected this way.
11.3.2. Wireless device input assignment and operation
Each input A to D can have one OASiS wireless device assigned to it. This way, triggering an
external wireless device has the same effect as GD-04 input activation by physical connection to
GND, effectively making the inputs radio-signal-activated.
Take the following steps to enroll a device:
1. Press and hold the ABCD button on the GD-04R module.
2. Entering enrollment mode is indicated after 5 seconds by flashing of the LED on the
GD-04R module – release the button.
3. Enroll up to 4 wireless devices to the GD-04R (send enrollment signals to the module). The
first device is assigned to the A input, the second one to the B input, etc. Wireless buttons
are enrolled by pressing them, wireless detectors by inserting their batteries. Enrollment is
confirmed by a long flash from the LED on the GD-04R.
Important: Enrolling the first device erases all the previously enrolled devices. Thus all
the desired devices should be enrolled in a single enrollment session.
4. Exit enrollment mode by pressing the ABCD button (enrollment is automatically terminated
after the fourth device has been assigned or after 40 seconds).
5. After enrollment mode termination, the LED on the module lights for approx. 5 seconds to
indicate enrollment data storage.
Notes:
• If the two buttons A and B are present on an RC-8x controller, the device can be enrolled by
pressing either A, B or A+B. The operational logic is then as follows: pressing A or A+B is
