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
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:
oInput activation is reported by SMS in response to detector triggering (body movement,
door opening, breaking glass, fire, tamper...)
oInput 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, see 11.3.4.
11.3.4. Using David for heating operation and status reporting
Each input A to D can have a wireless thermostat of the TP-8x series assigned to it (see
11.3.3).
•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:
oExceeding the upper temperature limit (e.g. 60°C) is responded to by an SMS report about
input activation.
oDropping 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.
•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
via an SMS instruction or 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
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.
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.cz.
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).
