We have collected a number of common questions and answers in our Frequently Asked Questions database below.

If you cannot find an answer to your question here, please submit a support request.

Installation problem – Product waiting for activation

Normally the SysManSMS Server will activate the license automatically over the GSM Network, within 1-2 Minutes. If this for some reason does not happen, you will have to activate the license over the Internet. Please read about how to manually activate your license. If you still have problems activating the license, please contact SysMan.

Installation problem – Server stops just after attempt to start

If new installation, or if the SIM card has been replaced when using GSM Modems from Wavecom or Sierra Wireless, you may see that the SysManSMS Server stops after running just for a few seconds. (The green desktop menu arrow blinks a few time, then turn into solid red circle) The servers log file (SysManSMS.log) will have the following entry:

ERR-100-9 Error contacting or init the GSM device
ERROR - PIN code or PUK code failure - Check SIM card

Most likely this is caused by the SIM card locker slide not properly in place. Please see this TechNote for GMS Modem installation instructions.

If this is checked to be OK, you may have a PIN or PUK code problem. With power off, remove the SIM card and install it in a standard mobile. Check the PIN code, and we also recomend to disable the PIN checking.

GSM Modem – Connect a modem to a Virtual PC

The SysManSMS Server works very well with Virtual Windows products like Hyper-V, VMWare and other. To connect the GSM Modem in a safe way, you should use a Serial-over-IP solution. With this you place a box with LAN and Serial connections where you like, and then you just install a driver on the Virtual PC to get a COM port for the GSM Modem. The most critical fail situation, where the LAN breaks, is taken care of with the SysManSMS Modem Watchdog. The Watchdog will let you know by sending out SMS alerts on its own.

GSM Modem – How to change COM port

If you have configured the SysManSMS Server to use a GSM Modem on a specific COM port and need to change the port, you will have to un-install and then re-install the software.

A quick workaround will be to edit the servers init file


with a Notepad carefully change the COM port number and then re-start SysManSMS Server.

GSM Modem – Signal problems

For the SysManSMS Server to run stable you will need a good GSM signal. You may check the signal either in the SysManSMS HTML Status page, the Quick status, or in the SysManSMS.log. It should in average read between 15 and 31. Normally the GSM Modem will use different GSM Base stations, and automatically switch between them dependent on the traffic. For this reason the signal can vary, and you can even loose the signal for a period. If this happens, the SysManSMS Server will wait for the GSM Modem to become ready, and then reconnect. To help a pure signal situation, you can either install an external antenna (maximum 10-12m away) or you can install a serial over IP solution. This can be placed anywhere on your LAN, and gives you more flexibility. If the LAN fails, the SysManSMS Modem Watchdog will send you alerts. The serial over IP is also the best solution where SysManSMS Server is installed on a Virtual PC. If the SysManSMS Server disconnect from the GSM Network, you may set it up to notify you via e-mails.

GSM Modem – Supported Modems with SysManSMS Server

SysManSMS Server has been tested and supports around 40 different GSM Modems. Some modems has limitations on GSM protocol support, and some are missing full character set support. The populare SysManSMS Watchdog function is supported on a few selected devices sold by SysMan.  For latest updates, see Device Support List.

GSM Modem support are closely connected to the GSM Operator capabilities. Please check known GSM Operator issues, if you have problems sending/receiving SMS messages with SysManSMS Server Software.

GSM Modem – Serial-over-ip solution – Firewall ports to open

If Moxa Nport is connected to a network behind a firewall, the following ports must be opened in the firewall:


Port 950 (~965) tcp data tcp, Port 966 (~981) tcp data flow control

All ports used:

Protocol Port No. Purpose
TCP 23 Telnet
TCP 80 Web Console
TCP 4900 1.Save Settings
2.Firmware upgrade
TCP 950(~965) Data port
TCP 966(~981) Command port
UDP 1029 1.Broadcast Search
2.Get Current Settings
3.Real COM Installer mapping

How to query the amount of messages sent by the SysManSMS Server?

You have 3 sources for statistical information:

First of all the, on the Right-Click Desktop Status Menu, you have access to Quick Status that shows you how many SMS’s sent and received since last midnight. From the same menu you can access the full SysManSMS HTML Status page which shows you the same, but also includes a total count since last restart of the server.

You also got a file in

…\SysManSMS\GSMserver\OUTPUT called computername_SysManSMS.csv

that contains some statistical counters to be used from other applications.
The last possibility you got, is to turn on the Accounting file. This is written to same local OUTPUT folder, and is called Accounting.csv. You turn it on and select accounting options, in the Accounting.ini file found in the GSMserver folder. You may read more about accounting in the User and Developers Guide.

Send SMS – How to send from remote command clients

The SysManSMS architecture allows remote client programs to send messages over the LAN to one or multiple SysManSMS Servers on the same network. The most common interface is to execute command lines with the SysManSMS Integration client (Iclient).

Below you will find some rules you have to follow in a remote client/server environment setup

We assume your SysManSMS Server is up and running, and are able to send/receive messages.

SysManSMS architecture uses port 139/445 (NetBios/Named Pipes)

Make sure your security settings on PC’s or Firewalls does not stop the above ports.

Use the SysManSMS SETUP (from CD or network) to install the client components

Make sure you select “Client Installation”, and also enter the SysManSMS server’s IP address or name.

Open a command line Window, got to …\SysManSMS\Iclient

Execute the following command to test sending from a client:
SysManSMS_Iclient.exe “::” “This is my first test from a remote client”
This line will send the above text to all members of your default Number File on the server

If this works fine, then setup your application to execute the same line automatically from application

Please Note:

The client must execute from a domain user account, alternatively you must use same username/password on both the SysManSMS Server and the client executing process. Default user account for SysManSMS Server is Local System Account.

If problems executing from your application, check the following:

  1. View the …\SysManSMS\Iclient\SysManSMS_Iclient.log file
  2. If you have a entry in this log for the same time as your application executed the command line, the settings in your application is OK, and a problem is on the SysManSMS side. If the manually execution from a command line window worked fine, your problem is most likely connected with account privileges and access rights.
  3. If you do not have any entries in the log at the time of execution, you have a setup problem in your application. Carefully follow the applications documentation on how to execute a command line program.

SysMan makes available information and hints on how to setup the most common application. Please visit the Solutions web page.

Send SMS – How to keep a processed Message File in INPUT Folder?

To save SMS Message Files after processing from the INPUT Server, you must go to SysManSMS Desktop Meny, enter “Server Settings” and then “Configure Server Settings”. This will open the Server’s Properties Window, and in the field ”File Selection for Server INPUT Files”, you add “,.BAK” behind the text file selection. Example: “.txt,.bak” will rename the .txt file to .bak after processing it.

Send SMS – How to send urls to the internal HTTP Server

As soon as you upgrade your SysManSMS Server to minimum V8.2, you will by default have a HTTP URL Service running on port 8080.

This Windows service is maintained by the kernel SysManSMS Server. If it stops it will be re-started, and if it fails you will be notified. The SysMan HTTP Server got powerful configuration options, including the possibility to name any parameter as you like to.

The configuration settings are all hold in the servers INI file, found in the server´s home directory. Among the advanced functions are the possibility to turn on DEBUG mode from the url. This tool will help you find out why a url does not execute as expected.

The SysManSMS User and Developer Guide have two pages describing how to configure and use the SysMan HTTP Server.

To test your HTTP Server, simply try one of the following urls:


http://localhost:8080/sms?recipients=your_mobile_number&message=This is my first url message

On older Windows Systems (2003/XP) you may need to install the Microsoft VC Distributable kit before the HTTP Service can run. This kit is placed in the HTTP Server’s home directory.

Send SMS – How to send http urls to numbers with a country code

This topic is only valid when using SysManSMS_HTTPclient for Microsoft IIS

Lets assume you are located in Norway, where the country code is “+47”. By default you can skip the country code and send like this:

yourserver/sms.aspx?message=Hello&recipients=97408361 (will send to 97408361 inside Norway)

If you include the “+47” (Norway) in front of the number, the plus may not work as expected.

yourserver/sms.aspx?message=Hello&recipients=+4797408361 (will send to 4797408361)

In URL strings a “+” indicate a space, and not a plus sign. Some operators will accept “47”, and automatically add a plus in front of the number, so you may see the above string will work inside your country.

Solution 1

The SysManSMS HTTP IIs Module supports a leading “00” to replace a plus sign.

yourserver/sms.aspx?message=Hello&recipients=004797408361 (will send to +4797408361)

Solution 2

It exists a filter function in SysManSMS HTTP Module which can automatically add, remove or replace leading characters in a number specification. This is activated in web.config file. The following two lines will make sure you add the “+” if your number starts with just “47”. (For other countries, add new “NumberFilter” lines for each country code)

<add key="NumberFilter" value="47,+"/>
<add key="NumberFilterMinimumLength" value="8"/>

This will result in the following handling of a line with the “+” specified:

yourserver/sms.aspx?message=Hello&recipients=+4797408361 (will send to +4797408361)

Solution 3

If you still like to be able to specify the “+”, you will have to code the plus sign in country code as “%2B”

yourserver/sms.aspx?message=Hello&recipients=%2b4797408361 (will send to +4797408361)

Send SMS – How to interface RSA with SysMan SMS Gateway

The secure SysManSMS Server is a perfect fit to safely forward SMS messages from RSA Authentication Manager, without sending secret information out to the Internet. RSA sends url’s which can be directed to your local SysManHTTP client module, which again uses the SysManSMS Server (SMS Gateway) for a direct GSM Network delivery.

Another solution would be to create your own PHP script to do the same. Below you will find a sample code to setup your IIs Server to receive RSA url’s and write message files into SysManSMS Server’s INPUT Folder.


$TEMPPATH   = 'c:\\temp';
$INPUTPATH  = 'c:\\program files\\SysManSMS\\GSMserver\\INPUT\\';
$RANDOM           = rand(5, 15).".txt";
$DIMS       = chr(161);
$MSGTYPE    = ""; // * makes it a flash message
$MESSAGE    = strtr($_REQUEST["message"],chr(10),chr(13));

$fcontent = $DIMS."SMS".$DIMS."+".$_REQUEST["to"].$MSGTYPE.$DIMS.$MESSAGE.$DIMS."HTTPclient".$DIMS."Fclient".$DIMS."\n";

$fp = fopen($FILETMP,'w+b');
echo "success";

Send SMS – How to setup SysManSMS to send repeating messages?

SysManSMS Server has an administrative notification service where you can have a small status message sent to you, either as sms, e-mail or both. This happens at midnight while the cleaning process runs. To enable this notification, use the Configure Server menu found inside the SysMan Desktop Menu icon.

In addition to this, you may setup as many repeating messages you like, sent either to one number or to a specified Number File (User group). You may repeat hourly, daily, weekly, monthly, yearly, every week, 2. week, 3rd  week or 4th week.
Setting up such repeating messages is easily done from the Desktop WINclient, found in SysManSMS Desktop Menu icon.

Send SMS – How to limit sending of unwanted SMS messages

In SysManSMS Server you got several techniques to limit sending out SMSs. First of all you got a SMS Storm control which limits the maximum number of SMS’s one mobile can receive per day. You may also set up different filters to search your texts and then either STOP, SEND, CONVERT or APPEND texts, if match found.

Send SMS – Which formats and protocols are supported by SysManSMS Server?

The SysManSMS Server is capable of forwarding texts to mobiles from almost any different source. Files can be dropped as free text, SysMan records, or XML formats, to an INPUT folder. Mails can be sent to a list of mobile numbers, or to individual numbers, either as part of address or taken from subject field. HTTP can by used for single urls or from a web based form. SNMP traps can be forwarded to mobiles. You may send from Command Line by use of small send programs, or you can implement SMS support in your own programs using the SysManSMS standard and .net APIs.

Send SMS – How to HOLD messages during night

In the Number File Editor (user group handling) you can select messages to any specific number to be HOLD (queued) for some hours. This is very useful, for example during nights. But this function does not work across dates.

To hold messages during night, you may specify HOLD 00-07, which will queue any message request from midnight until 07 in the morning. At 07 all queued messages will be sent.

HOLD settings across midnight (for example 19-07) is not supported in current versions.

Receive – How can a received SMS execute multiple server commands?

To have a incoming SMS on your server execute a list of programs or commands, you must create a Windows script file (.BAT) The name of this file (for example DOIT) will be the key to start the script from a mobile. The additional text will be available for the programs in your script as one of the parameters. Consult the SysManSMS User and Developers Guide for details on each program or server command you like to be executed.

Let’s create a script in the servers Programs folder called DOIT.bat

In our example, server’s number is 12345678, and the mobile’s is 87654321

REM Save DOIT.BAT in your servers Programs folder
REM Sending the SMS "DOIT NUMLIST1" will execute the following commands:

REM parameter %1 will contain mobile number that started this procedure
REM parameter %2 will contain the text sent from the mobile
REM parameter %3 will contain the time the message was sent from mobile

REM Make sure your BAT process has correct folder for the program to execute
cd \Program Files\SysManSMS\CMDclient

REM Use the CMDclient to send a command to a mobile or the server itself
SysManSMS_CMD.exe "12345678" ":VCFWD %1"

REM Make sure your BAT process has correct folder for the next program
cd \Program Files\SysManSMS\GSMserver\Programs

REM Execute a program from servers Programs folder
seti.exe %1 %2 %3

This is how your server log will look like after script execution:

Installation problem – Installing .NET Framework on Windows Server 2012

After installing SysManSMS Server on Windows Server 2012 you may encounter a message saying that “Microsoft .NET Framework 3.5 cannot be installed…” when setting up the tray menu tool.

Windows Server 2012 requires you to install .NET Framework 3.5 using the Server Manager GUI, or the DISM (Deployment Image Servicing and Management) command. The latter is the simplest solution. Open a command prompt with elevated rights (right-click and select “Run as Administrator”), and run the following command:

dism /online /enable-feature /featurename:NetFX3 /all /Source:d:\sources\sxs /LimitAccess

This will install the .NET Framework version 3.5 on your Windows Server.

Note that the SysManSMS Service itself does not require .NET Framework and you can run SysManSMS without installing .NET Framework 3.5.

Accessory – Backup battery replacement

Batteries in general will loose capacity over time. If the battery extention for the Sierra Wireless modem formerly supplied from SysMan has lost it’s capacity, you need to replace it with power from a UPS to stay protected from power outages. The battery accessory is no longer being produced, and can therefore not be replaced.

Installation problem – SIM card not supported

GSM Modems are industry type devices, and may not fully support some of the new SIM cards created for modern mobile phones. If you during installation of the SysManSMS Server see such problems, the Server will stop, and a typical error code in the SysManSMS.log file will be:

ERR-120-1 Can't get number of SIM locations in unit

You should first of all try to upgrade your SysManSMS Server to the latest release. If this does not help, you may have a unsupported SIM card.
Please see SIM Card Test Document for layout pictures of some tested  SIM cards for the Sierra Wireless FXT series.
