1.3. Safetycriteria
BeforeusingtheSVM,thereareseveralcriteriathattheusershouldmeet:
• TheSVMshouldbeinstalledinacontrolledenvironment(forreasonsofreprevention);
• The SVM should be supplied with power using a SELV-type power supply;
• ExternalEthernetshouldnotbeconnecteddirectlytoanSVM,butshouldbeconnectedviaan
overvoltage protection device;
• To reduce the probability of damage to the equipment, the SVM should be placed in an environment
protectedagainstelectrostaticdischarge(ESD);
• The SVM is intended for use as a modem or alarm dialler. The SVM is not intended for use as part of a
critical safety system in a critical process.
1.4. Checkingthedelivery
Check the packaging for damage. Contact your supplier immediately if the delivery is found to be
damaged or incomplete upon receipt.

2.1. Positioning
PositiontheSVMwhereitisnotaectedbydirectsunlightorotherheatsources.Choosetheplaceof
installation such that moisture cannot penetrate the device. The SVM can be mounted onto the TS35 rail
without screws. The permitted ambient temperature range for the electronics is -20°C to +50°C.

• Place the SIM card in the holder and slide this back into the SVM;
• Reconnect the supply voltage to switch the SVM on.
TheSVMshouldbecompletelyswitchedobeforetheSIMcardisinstalled.FittingorremovingtheSIM
card with the SVM switched on may damage the SIM card.

Page 7Manual SVM 4G modem | Back to Index
Adesys B.V. | Wateringen
The use of a ‘Prepaid’ SIM card for dialling purposes is strongly discouraged. The mobile network cannot
automatically request the call credit, which means that this can be run down without anyone noticing,
resultinginoutgoingnoticationscomingtoastandstill.
For use of the SVM servermode, the SVM should always contain a SIM card or have a subscription to a
static IP address. Consult your telecom provider.
2.4. Antenna
Connect the antenna cable to the SVM’s antenna connection. The antenna plus associated cable can be
obtainedfromAdésys.Theantennashouldbeaxedtoashighapointaspossibletoobtainthebest
possible range.

2.5. Powersupply
2.5.1. SV-20mainsadapter
A230VAC/12VDCmainsadapterwithitemnumberSV-20canbeobtainedasanoptiontosupplypowerto
the SVM.
Whenttingtheterminalblocktothepowersupplycable,ensurethatthepolarityplus(+)andminus(-)is
correct.
Anextrapowersupplyfuseisnotnecessaryhere.
If the SVM is not supplied with power using the above-mentioned mains adapter, the connection
regulations in the section below apply.
2.5.2. Powersupply
ConnecttheSVMtoaDCpowersupplyof15to35VDC(atleast8.5W)oratransformerof20to30VAC.
ThepowersupplyinputoftheSVMisnotgalvanicallyisolatedfromtheotherconnections.TheGND
connectionofthepowersupplyconnectorisdirectlyconnectedinternallytotheGNDconnectionofthe
input connector and the COM port.
If the SVM is connected to an application (process controller, PLC, computer, active sensor, etc.) without
galvanic isolation and the SVM is connected to the same power supply, there is a real chance of earth
loops and/or short circuits in this power supply.
2.6. Resetkey
Theresetkeyhasthreefunctions:rstofall,itisusedtointerruptthealarm.Pressingthisbrieyendsthe
currentnotication;theSMSmessagesthathavenotyetbeensentarenotsent.
A second function of the reset key is to restart the dialler. The dialler can be restarted by holding this key
down for a period of 8 seconds. This only occurs if a power supply is connected.
Ifnopowersupplyisconnected,theresetkeyfunctionsasanobutton.Holdingthekeydownfora
periodof8secondsswitchesothedialler.
Statuses of inputs will not be stored in a permanent memory. If the supply voltage fails, and the built-in
supercap is entirely discharged, the contents of this memory is lost. If the SVM is restarted manually, this
status will also be reset. When the supply voltage is restored, the SVM behaves as if it is being started up
forthersttime.Thismeansthat:
• After the supply voltage has been restored, only active inputs are reported once again;
• No Recovery message will be sent if the status of the input has been recovered during this power
failure.
The fourth functionality is for when there is something wrong and there seem to be no connection. By

SV-prog”.
2.9. 2G/4G connection
To use the SVM with a 2G/4G connection, a SIM card with Internet subscription should be installed in the
SVM. It is important that the correct APN, APN user and APN password are entered, otherwise the SVM will
not be able to connect. This can be entered in SV-prog in the 2G/4G window.
Network locking is possible. By entering a 2 or 4 in the GSM menu at the provider lock, it is possible to lock
the detector to 2G or 4G.
TheSVMdoesnotprovideanoticationifsomethinggoeswrongwiththeAPN.Formoreinformation
about the APN, please contact your provider.
3. SV-prog
3.1. Installation
Setting up the SVM can be done with the SV-prog tool. This program can be downloaded free of charge
from the Adésys website (www.adesys.nl/en/service/downloads). All settings will be stored in the internal
ashmemory.Itisnot possible to store the settings on the SIM card!
SV-prog must be installed on your PC before it can be used. Follow the instructions displayed on your
screen during the installation process. As soon as the installation process is complete, start the program
via the shortcut or via the program menu in MS Windows.
Connect the SVM to a power source and connect the SVM to the PC using the Ethernet cable set supplied.
The SVM can be connected to the local network or directly to the PC.
As soon as the SVM has been switched on, the tool will display this in the overview after a few seconds
andtheSVMcanbeconguredbyclickingit.Whensearchdiallersispressed,SV-progshowsallaccessible

ThestatusscreenprovidesyouwithinformationontheSVM.ExamplesofthisinformationaretheIMEI
code, the serial number, the MAC address and the current status of the inputs and alarms/errors.
3.3. Calllist
A call list is a group of contacts (telephone numbers) that can be coupled to the input to send an alarm
message or alarm recovery message. One to eight telephone numbers can be programmed into a call list.
3.4. I/O
Inputs are displayed in this window. All inputs can be set up separately from one another. Settings can
also be established here for Power Failure and System Errors.

supported. Status changes at the contact inputs can also be reported in this mode.
In this mode, the IP address obtained can be requested with the ATI4 command. This is particularly handy
if the set IP address is unknown, but this information is needed by the installer on site.
3.5.3. Server/clientmode
If the server/clientmode is switched on, the SVM waits in idle mode until a connection is established from
outside. If, however, the status of the contact inputs changes, or if data is sent to the RS-232 port/Ethernet
port, the SVM switches to clientmode and takes the initiative for the connection.
3.6. Advancedconnectionsettings
3.6.1. Connectionstringuponinitialconnection
A string has to be set up for sending to the server application as soon as the connection is transparent.
This informs the server which device is connected and that it is possible to communicate. This string is
senttotheserverapplicationwhenaconnectionisestablishedinthefollowingsituations:
• RS-232 connected, servermode;
• RS-232 connected, clientmode autologon.
3.6.2. Time-outs
Various time-outs have been implemented to prevent the modem from getting stuck in a particular state
due to unforeseen events. These ensure that the modem is reset and will then return to idle mode.
Data time-out
This time-out occurs if there is a connection to the server, but data is no longer coming in via the 4G
network.
• Timecongurablebetween1and10800minutes(7days).
• If the value 0 is entered, this time-out is not active.
Connect time-out
This time-out occurs if the connection with the server takes longer than the set period of time.
• Timecongurablebetween1and168hours(7days).
• If the value 0 is entered, this time-out is not active.
No activity time-out
This time-out occurs if there has been no connection with the server for a set period of time.
• Timecongurablebetween1and168hours(7days).
• If the value 0 is entered, this time-out is not active.
3.6.3. Terminateconnectionintheeventofalarm
If an alarm occurs whilst the SVM is sending data, in this option it is possible to choose whether the data

6. TheSVMasHayesmodem
TheSVMcanbeconguredwithmodememulation,withtheSVMbehavinglikeanystandardanalogue
modem. The basic set of AT commands thus results in the same response regardless of the selected
communication network. It can therefore be used for older PLCs based upon an old-fashioned modem.
6.1. ThebasicAT-commands
Inmostcases,theSVM’sbasicsetofATcommandsoersallcontroloptionsforsettingupamodem
connection. An AT command always begins with the letters AT (abbreviation for ‘attention’). This is
followed by a letter for the command, sometimes followed by a number as a parameter. The command
ends with a return, or enter. After receipt, the modem sends a response to indicate whether the command
has been carried out.
TheSVMATcommands:
Control commando’s
AT Control of connection, does not contain a command

6.1.1. ATA
After receiving a RING, the modem can be started by means of the ATA command. After the ATA command
has been sent, the responses CONNECT (...) or BUSY should be awaited. If data is transmitted via the COM
port during this time, the establishment of the connection is interrupted (without modem response).

6.1.3. ATE
ATE determines whether commands that have been typed are also sent back to a user. This is handy if
a user is in contact with the SVM for terminal emulation, as the user can see precisely what has been
entered. Some applications are, however, impeded by the returned characters. This is often the case
where the modem is controlled by an automated system, such as a PLC. After ATE the modem responds
with OK.
ATE0 (Echoo)typedcommandsarenotsentback
ATE1 (Echo on) typed commands are sent back (=standard)
6.1.4. ATH

6.1.8. ATO
ATO facilitates switching from command mode (see +++) to modem mode. This only takes place if a
modem connection has already been established. The modem responds with CONNECT (..).

ATQ1 (Quiet on) modem does not respond
6.1.10. ATS
The modem has so-called S registers to store certain settings. These registers can be read and described
using ATS.
• Use a question mark (?) to read an S register.
Forexample,thecommandATS0?readsSregister0.
• The equals sign (=) can be used to write to this register.
Forexample,ATS7=55setsSregister7tothevalue55.
The modem responds with the value of the requested register followed by OK.
TheSVMcontainsthefollowingSregisters:
• ATS0 controls automatic answering if the modem is called. If S0 is set to 0, there is no automatic
answering(=standard).Everyvaluegreaterthan0signiesthenumberofringsafterwhichthemodem
must pick up. The modem starts up automatically in the same way as when the ATA command is used.
The modem then responds with CONNECT (...) or BUSY. If data is transmitted via the COM port during
this time, the establishment of the connection is interrupted (without modem response).
• ATS7determinesthemaximumtimethatmaybetakentoestablishamodemconnection.Ifthe
connectionhasnotbeenestablishedafterthespeciedtime(inseconds),theattemptissuspendedand
the modem goes into idle mode. The standard setting is 90 seconds (ATS7=90).
6.1.11. ATV
ATVdetermineswhetherthemodemresponsesaregivenintheformoflegibletextoranumericalcode.
The latter is needed for certain automated systems that control the modem. The modem responds with
OK (or 0).
ATV0 Modem gives numerical responses (numerical code)
ATV1 Modemgivestextresponses(=standard)
6.1.12. ATX
Response to switchboard signals; not supported, but responds with OK for compatibility.
6.1.13. ATZ
ATZ resets the modem to its initial position. All settings are returned to the last stored value and any
connection is interrupted. The modem response is OK.
6.1.14. AT\N
