Using A Pc Running Gdlink Software; Sms Instructions - jablotron DAVID GD-04 User Manual

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 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.cz web site.
David's communication protocol is available for use by other computer programs which can
thus utilize GD-04 transfers (including programming instructions or GSM status information).

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:
where:
is the access (programming) code, required at the start of any programming
PC
SMS message* (2 to 8 ASCII characters, the factory default setting is PC)
is a comma separator
,
is the name of the instruction for programming the text you wish to use for
ARX
switching relay X on via SMS. The desired text ("heating on") follows, separated
by a comma.
is similar to ARX, related to switching relay X off.
DRX
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.
