Aquatrac Wireless Communications With EvDO

Setting up the EvDO Router

Abstract

This section will show you the settings that need to be made on the router (Cradlepoint CTR500) to allow for remote communications to the Aquatrac controller.

NOTE: This section assumes the following:
  • The Aquatrac controller used in this example is a Multiflex
  • The IP Address of the Multiflex is 10.10.6.106
  • The EvDO Router used in this example is the Cradlepoint CTR500
  • The Data Card used in this example is the Merlin EX720
  • You know how to make changes to the controller's communications (i.e. IP Address, Port Numbers, etc)
  • The data card is initialized
  • The data card has a Public IP Address assigned to it
  • The data card is installed in the EvDO router
  • The state of the Cradlepoint router is in its default settings (out of the box)

Step 1: Change the LAN IP Address of the Router

  1. Using an Ethernet Straight cable (CAT5), connect your computer to the Cradlepoint CTR500
  2. Allow two to five minutes for the router to assign an IP Address to your computer (Note: your computer must be in DHCP mode)
  3. Open a web browser (Internet Explorer, Firefox, Chrome, etc)
  4. Go to http://192.168.0.1 (this is the default address of the Cradlepoint CTR500 router)
  5. Enter the password of the router (the default password for the Cradlepoint is the last six characters of the Cradlepoint's MAC Address)

  6. In the Cradlepoint admin pages, go to Basic > Network

  7. Change the IP Address of the Cradlepoint from 192.168.0.1 to 10.10.6.1, then click "Save Settings"

    NOTE: The important concept to understand here is that we have just configured the IP Address of the router so that it matches the first three sets of numbers (Octets) of the Multiflex. In other words, the specific IP Address value doesn't really matter, just as long as the first three sets of numbers on the router and Multiflex match.

    For example: If the IP Address of the Multiflex is 192.168.45.122, then we can set the IP Address of the router to 192.168.45.1. Likewise, if the IP Address of the router was configured to be 172.34.21.1, then we could configure the IP Address of the Multiflex to be set to 172.34.21.45.

  8. Reboot the router
  9. Wait two to five minutes for the router to assign your computer a new IP Address

Step 2: Configure Router for Controller Remote Access

  1. In your web browser, go to http://10.10.6.1 then login to the router

  2. In the Cradlepoint admin pages, go to Advanced > Virtual Server

  3. In the "ADD VIRTUAL SERVER RULE" section, enter the following information:

    • Enable: Selected (Checked)
    • Name: MFlex Trackster
    • IP Address: 10.10.6.106 (This is the IP Address of the Aquatrac controller)
    • Protocol: TCP
    • Public Port: 23 - Remember this Public Port number! (This is the Port number that the Aquatrac controller communicates with Trackster (or Telnet))
    • Private Port: 23 (This is the Port number that the Aquatrac controller communicates with Trackster (or Telnet))
    • Schedule: Always
    • Inbound Filter: Allow All

  4. Click the "Save" button.
  5. In the "ADD VIRTUAL SERVER RULE" section, enter the following information:

    • Enable: Selected (Checked)
    • Name: MFlex Browser
    • IP Address: 10.10.6.106 (This is the IP Address of the Aquatrac controller)
    • Protocol: TCP
    • Public Port: 800 - Remember this Public Port number! (The reason for setting a port number of 800 is due to the fact that many EvDO Providers block Port 80. To work around this problem, we are using an arbitrary Port Number.)
    • Private Port: 80 (This is the Port number that the Aquatrac controller communicates with your web browser)
    • Schedule: Always
    • Inbound Filter: Allow All

  6. Click the "Save" button.
  7. Click the "Save Settings" button

Step 3: Change Logon Passwords

  1. In the Cradlepoint admin pages, go to Tools > Admin

    1. In the "ADMIN PASSWORD" section, enter a new password (Remember this password for future use!)
    2. In the "INTERNET ACCESS PASSWORD" section, enter a new password (Remember this password for future use!)
    3. In the "ADMINISTRATION" section, select "Enable Remote Management"
    4. Take note of the "Remote Admin Port" number. The default value is 8080. This port number is critical when you need to access the router Admin Pages from a remote location.

Step 4: Determine IP Address of Device

  1. In the Cradlepoint admin pages, go to Status > Device Info

  2. In the "WAN" section, write down the "IP Address" of the device. This will be the IP Address that you use to connect to the controller from a remote location.
NOTE: If an IP Address is not defined, you will need to initialize your Data Card

Step 5: Router Configuration Done!

Now that you have configured the router, you should be able to communicate with the router and the Aquatrac controller via the Internet. Here's how...
  1. Disconnect the Ethernet cable from your computer and plug it into the Aquatrac Controller's Ethernet port (CAT5 Jack)
  2. Connect your computer to the Internet
  3. Open a web browser (Internet Explorer, Firefox, etc)
  4. Connect to Router Admin Pages

    In your web browser, go to the IP Address of the router (actually, it's the IP Address of the data card) that you wrote down in Step 4 and make sure you append the "Remote Admin Port to the IP Address. For example: http://72.62.206.164:8080

  5. Logon to the router using the "INTERNET ACCESS PASSWORD" you defined in Step 3.

Connect to Multiflex

  1. In your web browser, go to the IP Address of the router (actually, it's the IP Address of the data card) that you wrote down in Step 4 and make sure you append the "Public Port of the "MFlex Browser" setting that you wrote down in Step 2.5 to the IP Address. For example: http://72.62.206.164:800

  2. Congratulations! You now have full access to the Aquatrac controller from a remote location.
