characters), text erased by DRX, ,
Example: DRY,ventilator off
Use TMY for relay Y.
t..t = switch-on period in seconds, or zero
• 1 to 10h entered in seconds, minutes(m) or
hours(h) ( 3600s = 60m = 1h)
• The relay works as a time-switch, activated via
switch-on SMSes or dialling-in. Deactivation is by
time-limit expiration or via switch-off SMSes.
• 0: no time-limit applies, dialling-in is responded to
with toggle logic: on – off – on...
Use ADY for relay Y.
x..x = tel. number. Up to 50 numbers can be entered
(in a single instruction or gradually). The numbers
are added to the list of authorised numbers.
Example: ADX, 777123456, +420608503211
authorises two new numbers for relay X control.
Use LDY for relay Y.
x..x = tel. number. The numbers are added to the list
of authorised numbers, up to 50 in total.
n = limit in the number of calls (1 to 99), exceeding
the limit removes the number from the list – this is
reported to the service number by SMS.
Example: LDX, 777123457, 31 authorises a new
number for relay X control for a maximum of 31 calls.
Use EDY for relay Y. x..x = tel. number. The
numbers (up to 50) are removed from the list.
Example: EDX, 777123457 de-authorises a
single tel. number used for relay X control.
Use ATB for input B, etc.
xxx..x = text (up to 30 characters*)
Example: ATC, heating on
Instruction ATA , , erases the text = no reports
Use DTB for input B, etc.
xxx..x = text (up to 30 characters*)
Example: DTC, heating off
Instruction DTA , , erases the text = no reports
Use TNB for input B, etc.
x..x = tel. number, up to 8 for each input. All
previously stored numbers are erased. Use TNA,
to empty the list.
Example: TND, 777123456, 608123456 sets
David to report input D events to 2 numbers
, n = 1 (ON), 0 (OFF). If
Use TNB for input B, etc.
set to ON, every SMS report is followed by a call.
If you answer the call, you hear a constant tone =
activation, or an interrupted tone = deactivation.

The GD-04 "David" GSM communicator
Factory
The GD-04 module got its name from David, a biblical king who outsmarted Goliath, a giant. In our
default
case, Goliath is meant to be the GSM network. We hope that the skills of your tiny David will help you
manage the giant.
