5.5.2 CDMA Setup

The Digi Connect® WAN 3G IA modem (Verizon: DG-WAN-B205, Sprint: DCWAN- B105) is also able to be provisioned by a cellular service carrier to work on a CDMA network. An account must be set up with a local CDMA cellular service provider. To activate the modem, you will require an IP Address supplied by the service carrier to be assigned to the modem.

The cellular service provider will require the modem IMEI and MEID (also known as ESN) numbers in order to provision the modem for use on the chosen network.

The following are the steps required to set up the CDMA modem:

  1. Attach the antenna to the modem.
  2. Connect the Ethernet Cable (null modem cable) from the modem to your PC.
  3. Use the STS Remote Station, with your connected battery, STS Controller, and Distribution Box to connect the modem to a power supply. Turn the modem on using the Modem Control option in the STS Controller.
  4. After the connection has been established, you should see the message as shown in Figure 5-11 at the bottom right of your PC screen. Double-click the network icon.
  5. If using Windows XP, in the Local Area Connection Status window, the Support tab should display the same Default Gateway and Subnet Mask, as shown in Figure 5-12. The IP Address does not have to match, but it should begin with 192.168.1.XXX (XXX is any number between 2 and 255), thus matching the Default Gateway. Close the window.
  6. Note:

    Steps 4 and 5 are based on the Windows XP Operating System. Other Operating Systems may require another path to access the Local Area Connection Status.

  7. Open your web browser and enter the IP Address "" in the URL address bar. The main configuration menu of the modem will be displayed.
  8. Select "Mobile" under the Configuration menu.

    It is recommended to set the TCP Port to 49200 if using a Windows 7 computer, and 49800 if using Windows 8.

  10. If the modem has been provisioned properly, you should see the proper Service Provider listed. Make sure the Service Provider selected is correct. Click on "Serial Ports" under the Configuration menu and click on the Port that is available. This should be Port 1 by default.
  11. In the Port Profile window, select "TCP Sockets" and click Apply.
  12. Make sure the Serial Port Configuration matches the screen in Figure 5-14. Enter the IP Address provided by your Internet Service Provider in the IP Address field. The TCP Port should be set to either "49152", "49200", or "49800" depending on your setup and Operating System. When finished, click Apply.
  13. Select Basic Serial Port Settings to set up the communication parameters. The following settings should be entered:
    • Baud Rate: 115200 bits/second
    • Data Bits: 8
    • Parity: None
    • Stop Bits: 1
    • Flow Control: None
    When finished, click Apply

In the STS Controller Main Menu select "STS Gold Setup", then select "Modem Port Setup". Enter the same settings as above for the Baud Rate, Data Bits, Parity, Stop Bits, and Flow Control.

The modem is now configured and ready to be used with the STS Telemetry System.
