This chapter contains information about connection between device (Datalogger, ATP serie) and computer throuth modem using GPRS (connection through ethernet/internet).

Communication scheme

How it works

Communication through modem is communication by ethernet/internet. Because modem mostly have no public ip address, you can't connect to it directly from your computer. For solution of this problem is used M2M system. M2M communication requires following configuration parts:

1. Modem to M2M server connection
   Configuration
2. PC to M2M server connection
   Configuration
3. Connection between computer and device (modem)
   It means define communication interface in the program for dataloggers (Datalogger/ATP serie communication interface Modem)
