The Raven XT is an IP modem designed to operate on the internet via cell connections.


These instructions assume that you have this equipment:

  • Raven XT Modem with antenna
  • SIM card with data service and a static IP address. (Dynamic IPs will be discussed in a separate tech note.) Remove the front panel of the modem to insert the SIM card, but wait until later to do this.
  • Power supply for modem. The modem accepts a nominal 12 Vdc up to 15 Vdc.
  • AceManager and ModemDoctor. Install these two programs on your PC. You can find them on the CD supplied with the modem or download them from the Sierra Wireless website. On the CD, look in theTools and Utilities folder.
  • Serial cable to connect PC to modem. This cable has straight -though conductors with a DB9 male and DB9 female connectors. If your PC does not have an RS232 serial port, you will need a USB to serial adaptor.
  • Null-modem serial cable to connect modem to logger. This cable has cross-over wires. Male DB9 connectors are required at both ends. If necessary, you can buy a “gender bender” adaptor to convert a female connector to a male connector.

Step 1: Clear all Settings from the Modem
