Function:
Hands free GSM door entry phone with preprogrammed
numbers for 1 or 2 buttons with name labels:
1. Outgoing call: After button press is dialled first number
from saved list of numbers. The numbers are saved
under names ABUTTON1 to ABUTTON7 –it means
first number under name ABUTTON1. When called
party is busy or not available then automatically second
number under name ABUTTON2 is dialled etc.. When
called party picks up the call the connection is
established and next numbers are not dial (the same
valid for second button and line BBUTTON).
2. Incoming call: up settings will be incoming call picked
up either for all calls or for saved numbers on SIM card
only. (connection for saved numbers only). GDI might
also reject incoming calls (see later in relay function).
Before picks up might GDI alert by preprogrammed
melody ( adjustable) . (Notification for call establishing
–listen in control).
2 remotely controlled switching relay. Each can be
controlled up settings by different ways:
1. By ringing –incoming call is rejected (confirmation of
command accept) and simoultaneously is activated
selected relay for preprogrammed time. Selected relay
can be activated:
a. only from numbers saved in the phone list of the SIM
card, or
b. from any number
2. By code –during voice communication (incoming as
same as outgoing call) . The 1 digit code by DTMF
might be dialled by called party for relay activation ( for
preprogrammed time). For each relay you can
programm different code.
3. By SMS –you can remotely switch ON/OFF selected
relay or activate relay for certain time mention in SMS.

3
Relays might be controlled only from preprogrammed
numbers at GDI SIM card.
4. camera mode –selected relay is ON by picking up the
call and it is OFF by hanging up the call.
5. lighting mode –selected relay is ON by picking up the
call and it stays ON for preprogrammed time after hang
up.
6. button mode –selected relay is ON after button press
and stays ON for preprogrammed time.
1 adjustable input :
1. SMS sending „ALARM ON“ to preprogrammed number
when input is short circuit against ground. SMS
„ALARM OFF“ to next preprogrammed number when
input is disconnected. It might be programmed 1
number only (ON/OFF). Then is send 1 SMS only up
selected status.
2. opening detection. When input is activated during call
(for example by gate ( door) opening ) the GDI
generates into a call 3 short beeps for time of input
activation.
Voice signalling of different status. Up settings might be
different status signalling by voice . ( language adjustable).
When is voice signalling presented during a call it is hearable
on both sides of connection (for example „open“)
Detection of start / restart. GDI indicates the start device
(power) switch relay1 on 7s. This function can be used for
example to automatically open after restoration of power
supply, remote reboot any device (ringing) with automatic
restart after power is restored, etc

Note: All programmed parametres are saved on the SIM. The
SIM you can insert into GDI already preprogrammed or setup
GDI after switching ON ( via bellow).
When you want use calls rejection ( ringing), ask your
GSM provider to switch OFF voice mail at used SIM card!
SIM preprogramming
1. SIM which you desire to use insert to various mobile
phone.
2. When PIN is setup –cancel it (or setup PIN to 1234)
3. When you will want to make remote setting save on the
SIM phone number of desired mobile under name
ADMIN1.
4. On the SIM save phone number which should be dial
after pressing button 1 (A), under name „ABUTTON1“.
5. When you have GDI with 2 numbers –save on the SIM
also phone number which will be dial after pressing
button 2 (B) , under name „BBUTTON1“.
6. When you want dial automatically next numbers ( when
first number is busy or not available) then save those
numbers under appropriate names ABUTTON2..7 and
BBUTTON2..7
7. Similiary you can programm setting of all parametres
(programming table at the end of manual)
The way of phone numbers saving on the SIM depends on
mobile phone type. Please double check that you save
numbers to SIM card and not to internal mobile phone
memory!

2. Switch on GDI
When all neccessary cables are connected (relay, locks, etc.)
CAUTION: antenna must be also connected. Then connect
speaker connector and connect PSU. The RED LED lights on
and after a while yellow LED start flashing (via table). The GDI
signalling by tones or by voice SIM reading, GSM network
registration and ready for operation (via table). Now you can
put on front panel of GDI but dont screw it.
When SIM is preprogrammed you can try first connection –
push the button. The GDI must dial programmed phone
number. When SIM is not preprogrammed then first step is
SIM programming (via following article (3)) and then try
connection. After voice connection you can adjust setting of
speaker volume. Then screw up front panel of GDI.
3. Programm GDI parametres
The parametres in GDI ( must be switch on) you can
programm by 2 ways. By SMS or by PC ( special sw) via USB
port.
A) Programming by SMS.
Due security reasons you can programm GDI parametres from
authorised numbers only. They are saved on SIM under
names ADMIN1 to ADMIN9.
SMS are always written by BIG LETTERS
Each SMS elements are splited by space ( words). First word
is always command. Further word (s) is one or more
parametres.
Example: INIT ADMIN1 [phone]
All commands are in appropriate table at the end of manual

12
1. During first setting when SIM doesnt contents any ADMINx
name is neccessary such number insert to SIM by SMS with
command INIT. SMS you can send from various number.
When SIM already contents even one number under name
ADMINx the command is ignored.
2. When you need control relay eventually setup GDI from
next ADMIN numbers perform following: from mobile phone
with ADMINx number send progressivelly SMS to GDI with
numbers of next ADMINx in SMS format: WRITE ADMIN2
+420xxxxxxxxx (WRITE ADMIN3… etc.)
3. From mobile phone with numbers ADMINx send
progressively SMS to GDI with numbers which should be
dial after button press, SMS format: WRITE ABUTTON1
+420xxxxxxxxx (WRITE BBUTTON1… etc..)
4. Up your needs send next SMS with other parametres for
opening by ringing, SMS alarm sending , etc..
5. Setup parametres GDI (via table). Parametres you can
setup individually for each parametr appropriate SMS.
When you need setup more parametres simoultaneously we
recommend use SMS for batch setting. By SMS „READ
PAR“ read firstly current setting to your mobile.
By editor of SMS messages change at received SMS word
READ to WRITE as same as adjust parametres up your
needs. Such adjusted SMS send back to GDI as reply. The
parametres will be setup.
A) Setting by PC through USB via GDIset ( optional)
1. Connect MiniUSB cable to PC as same as to
programming module –green LED must light on at the
module. During first usage
USB driver might be
installed. USB driver is
available at attached CD.

2. Remove front cover of GDI and insert connector of
programing modul into GDI (via picture). On
programming modul must light on red LED
(It is flashing same way like yellow LED on GDI)
3. Run GDIset programm and setup appropriate port.
4. Program control GDI connection. After that display GSM
signal strength and voltage on GDI (back up ACU). Now
you can programm:
