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 or switch to a LAN based modem. 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. If the SysManSMS Server disconnects from the GSM Network, you may set it up to notify you via e-mails.

The SysManSMS Server works very well with virtual server products like Hyper-V, VMWare and others.

The best option would be to use a modem with built-in LAN interface, such as the “SysMan 2G/3G/4G LAN modem with Watchdog”. This modem can be purchased from SysMan directly or through resellers.

If you have a serial modem, you should use a Serial-over-IP solution like the Moxa nPort 5110.

If you have a USB modem, you should use a solution like anywhereUSB.

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.

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.
