Example GPRS Application > Connecting Remote Serial Devices to Servers using GPRS Networks A GPRS network allows remote monitoring or data collection equipment with serial RS232 connection to send data back to a command center. The GPRS router can be easily configured to relay any data received at its RS232 serial port to a data-collecting server with internet connection (static IP or with DYNDNS assigned name) over a GPRS network.

Example Solution In this example, an array of vibration sensitive sensors are connected to a monitoring and data logger. The data-logger is configured to send our an ASCII string of connected data via its RS232 serial port every 15 minutes. This data is received at the serial port of a FATBOX GPRSV2 router, encapsulated into TCP/IP packets and sent reliably over a GPRS network to an internet connected server running a monitoring software. The server needs to be connected to the internet via a static IP address or assiged a name using a DYNDNS service like www.dyndns.org. Some of the features of the FATBOX GPRSV2 that facilitates succesful implementation of this solution includes, Serial to TCP/IP or UDP transparent transport function Dual-SIM card support for redundancy in critical applications Sleep mode (cellular link disconnected) when serial port data idle to save data costs and power Sleep mode 'wake' on data or remote 'call', e.g. from server using a modem Dynamic DNS client to use with dynamic IP addressed SIM to allow remote connection from server Built in Ethernet router for easy migration to newer IP based devices using same network and router Wide power supply 5~30VDC ensure stability of operation Industrial design and all metal construction for durability Typical Application Examples Backup for DUAL WAN (e.g. ADSL, DSL, Fiber or Cable) connection to the Internet Automatic backup for WAN access to the internet (without DUAL WAN router). Automatic backup for WAN (and VPN) access to the internet using VRRP.
