Establishing Cellular Service

Either a static IP account or a dynamic IP account needs to be established. A static IP account eliminates the need for a third party Dynamic Domain Name System (DDNS) such as IP manager. The DDNS translates the dynamic IP address to a domain name so that the RavenXTG can be contacted as if it had a static IP address.

To setup an account, call AT&T at 1-800-331-0500 and ask for an unrestricted data account for an GPRS modem. After the account has been setup, mobile termination needs to be configured onto the account to make the modem accessible through the Internet. Typically this is done by adding I2gold APN to the account. A data account with an I2gold APN will have a Static IP address.

Please note that at one time, feature code G821 was used instead of the I2gold APN. Feature code G821 has been discontinued, and all RavenXTGs need either an I2gold APN or custom APN.

AT&T can also setup a custom APN. A custom APN may offer more efficient routing and better security for large cellular phone networks. It will take four to six weeks for AT&T to develop a custom APN and cost about $250.00.

AT&T will provide a SIMM card for each modem. In some cases the SIMM card can be picked up at a local AT&T store. The SIMM card must be installed inside of the modem (see manual).

Configuring the Modem

The RavenXTG is configured using the following software:

  • AceManager software—activates the modem and configures the generic parameters of the modem. This software can be downloaded at no charge.

    See the Downloads.

  • Campbell Scientific’s Raven GPRS Template—used with Airlink AceManager software to configure the modem. The template sets up the Raven serial interface, which is specific to Campbell Scientific systems. The Raven GPRS Template can be downloaded at no charge.

    See the Downloads.

Datalogger Considerations

The modem connects to the datalogger's RS-232 port via a 9-pin male-to-male null modem cable; Campbell Scientific offers the 18663 null modem cable (see Ordering). Alternatively, the modem can be connected the the datalogger's CS I/O port, but an SC105 or SC932A interface is required.

Compatible Contemporary Dataloggers

Compatible Retired Dataloggers

CR500 CR510 CR10 CR10X 21X CR23X CR9000 CR5000

*Although the CR9000 and CR9000X are compatible, the RavenXTG does not support their fastest communication rates, and therefore may not be practical for many CR9000(X) applications.

Power Considerations

A power cable included with the modem connects to the datalogger’s 12 V or switched 12 V terminal. Connection to the switched 12 V terminal allows the datalogger to switch power to the modem during scheduled transmission intervals, thereby conserving power. When using the switched 12 V terminal, the modem can be powered with a BP12 battery, CH100 or CH200 regulator, and SP10 solar panel. For help on analyzing your system’s power requirements, refer to our Power Supply product brochure or application note.

Enclosure Considerations

A desiccated, non-condensing environment is required. The 14394 Mounting Kit includes hardware for securing the RavenXTG to an enclosure backplate (see Ordering Info).
