One problem i have is that my PC is on a local network and the IP my computer has, is the local IP. The server has a different IP through we connect to the internet. Which IP I must use and how?
I know almost nothing about TCP/IP (i have use the Labview TCP/IP functions successfully at our local network) and i would like to ask for informations. I know it is a little irrelevant with Labview, but as there are many users who uses GPRS modules, i would like informations about how to connect a GPRS module through TCP/IP. Simple examples will be the best.
Any informations, links, recommended books, will be highly appreciated.
Solved! Go to Solution.

It's not fully clear to me what you want to do but I assume that you want to use a GPRS modem to connect your computer to internet. This is entirely independant of LabVIEW. First you need to install a modem in your system and configure it to communicate with the GPRS modem. It's mostly like installing any other modem in your system and if you use Windows using the Modem Wizard that can be accessed from the Phone and Modem Options Control Panel or similar depending on your Windows version is probably a good start. You will want to install a Standard 19200 or 38400 modem in most cases.

Thanks for answering Rolf.
To be more clear : i have a GSM/GPRS module (like the well known Wavecom's modules (or Falcom, Telit...)). They accept AT commands and they have a D-sub-9 serial connector. They connect to serial port of the PC. I want to connect to the internet with TCP/IP (by sending AT commands). But i can not find any manual..! The module have some commands for TCP/IP but no explanation or examples. Those modems have no drivers, they accept only AT commands.
For example i have to set APN and IP Address which i don't understant what i should write to. It is independant of Labview but i do not know where to look for information.
If someone knows anything similar please reply.

I don't want to sound bold, but there is not much more to it. The challange will be to setup the modem right in your version of Windows, which is a typical Windows problem although one that less and less people get to deal with nowadays and to get your network provider to give you the correct information to be able to connect to their network. All in all things that we here can help even less with than more dedicated forums such as Windows support or your network providers support line. Here in the Netherlands the dialup string to be configured is different for each mobile network provider. Also there are variations depending on the modem type.

Hi
Just Geussing, but it sounds like you need to know which IP's are available from the server or if it runs DHCP. Then program a suitable IP address into the device in a simalar fashion to setting a static IP on a pc. Then the module may be able to start TCPIP command from the server and eventually your pc. There may be a way to communicate directly to the pc without going through the server, however i am unsure about that. Think its called a bridge or something???
Trying to be helpfull but im clutching at straws here 🙂
