  • Cellular IP Modems (Gateways) allow the user to communicate with serial or ethernet devices from a remote location.
  • Cellular networks use GSM (Global System for Mobile Communication) as a global standard.
  • Data is transmitted to the remote device throught the use of the internet and a cellular modem.
  • To gain a better understanding, the diagram below is broken into four sections:
  • a) Server b) Internet c) Dynamic Cellular IP Network d) Moxa OnCell G3150 IP Modem

  • Server
  • The first step is assign a static IP address on the laptop.
  • Step 1
  • Windows XP:  Click Start > Control Panel > Network Connections.
  • Windows 7:     Click Start > Control Panel > Network and Sharing Center.
  • Step 2
  • Right click on Local Area Connections and select Properties.
  • Step 3
  • Highlight Internet Protocol (TCP/IP) and click Properties.

 

  • Step 4
  • Click “Use the following IP address” and enter an IP address that is on the same subnet as your network or the LAN IP address of your router.
  • Example: If the Moxa OnCell G3150 LAN IP address is 192.168.127.254, set the IP address of the computer to 192.168.127.x, where x is a number between 1 and 253, provided this IP address is not being used on your network.
  • Step 5
  • Click OK twice to save your settings.

  • Internet
  • A static IP address must be requested from your ISP (Internet Service Provider).
  • Most internet users use dynamic IP addresses, which means each time they connect to the internet, their ISP assigns a new IP address.
  • In order to communicate with the Moxa Oncell G3150 in the field, a static IP address must be assigned to the router.
  • This static IP address is also identified in the Moxa OnCell G3150.
  • Dyanamic Cellular  IP Network
  • Obtain a M2M (machine to machine) data sim card.  The data sim card must have a dynamic IP address and an APN (Access Point Name) from the M2M service provider.
  • M2M allows machines to communicate with one another over a cellular network.
  • M2M is a platform that allows the user to diagnose issues, monitor, and to receive alerts.
  • The Moxa OnCell G3150 is an industrial RS-232 and RS-232/422/485 GSM/GPRS/EDGE IP gateways (modem).
  • To better understand M2M cellular providers, click on the following weblink http://m2m.com/index.jspa (Community for machine-to-machine, embedded wireless, and connected consumer devices development).

 

  • Moxa OnCell G3150 IP Modems (Gateway)
  • Cellular IP Modems use a non proprietary cellular technology called GSM (Global System for Mobile Communication).
  • GSM is commonly used for voice calls and SMS (Short Message Service).
  • In sending and receiving high speed data, GPRS (General Packet Radio Service) is recommended.
  • GPRS is a digital based protocol that runs over the GSM network.
  • GPRS is based on data and GSM is based on time.
  • GPRS has two advantages over GSM: 1) Communication speed   2) GPRS enable devices are in the “always on” state. is communication speed.
  • The communication speed of GPRS is 115Kbs and GSM is 9.6Kbs. This means that GPRS is roughly 11 times faster than GSM.
  • The second advantage is GPRS enabled devices are in the “always on” state. This means that you are only charged for the amont of data sent and received.
