Connect to iSIC V2 Logger Terminal

  1. Download the free open source terminal program Tera Term (or use a comparable terminal program) here.
    1. Select the link for the ‘teraterm-4.97.exe file’. The download will begin automatically.
    2. Complete the installation with the default components shown.
  2. Connect a RS485-USB cable to the PC.
    1. Allow Windows to download the driver automatically.
    2. Verify the COM port of the cable once the download is complete by viewing the Ports (COM & LPT) segment of Window’s Device Manager.
  3. Launch Tera Term. The following screen will appear. Click Cancel.
  4. Navigate to Setup|Serial Port and enter the COM port of the USB cable in addition to the other serial settings shown in the screenshot below and click OK.
  5. Connect the UW-end of a UW6-USB cable to the iSIC-V2 (disconnecting any existing 6-pin power plug connected) . The logger will power from the 5V input and a startup message will display.
    1. Certain units in Stainless Steel Enclosures will have a USB pre-wired into one of the two terminal strips of the logger for terminal communication with the system powered under 12V.

Enter the Cell Terminal

  1. Depending on the schedule, the iSIC-V2 may attempt to take a reading or send data during configuration and output text similar to that in the image below. Hit Enter or Ctrl+C to stop the text and open up a command line.
  2. Send the cellterm command to open up a communication channel with the modem.
  3. Turn on the cell modem using the !on command.
  4. Send the AT+CGDCONT=<cid>,<PDPType>,<APN> command to set the APN
    1. <cid>
      1. Will typically be 1 for 2G3G global modems, 3G AT&T and Verizon modems, and 4G AT&T modems.
      2. Will be 3 for most Verizon 4G modems
    2. <PDPType>– note the double quotation before and after must be included
      1. Is “IP” for 2G3G global modems
      2. Is “IPV4V6” for most 4G networks
      3. If using one version does not seem to work with the APN, try the other option.
    3. <APN>
      1. If unknown, consult with the cellular provider. Common APNs for Domestic Verizon and AT&T accounts are provided below for reference.
        AT&T (dynamic IP)broadband
        AT&T (static IP)i2gold
        VZW (dynamic IP)vzwinternet
        VZW (static IP)xx.vzwstaticxx is dependent on the account region

        ne01.vzwstatic (North East)

        nw01.vzwstatic (North West)

        so01.vzwstatic (South)

        mw01.vzwstatic (Midwest)

        we01.vzwstatic (West)

      2. Several preset commands are available. Send the !? command to see what is available. In the screenshot below !attapn, !attapn3g and !vzwapn are available to automatically configure the APN for dynamic 4G/3G AT&T and 4G Verizon modem, respectively.
    4. Example of manually setting an AT&T 3G modem with a dynamic APN.
  5. Send the ^C (Ctrl+C) command to verify the configured APN matches what was sent.
  6. Send the ^S (Ctrl+S) command repeatedly until the signal quality is 9 or higher (leading digit).
  7. Send the ^G (Ctrl+G) command repeatedly until 0,1  is returned.
  8. Send the ^R (Ctrl+R) command and wait up to 30 seconds for a response. This will report the IP address in the form the modem acquired if it was able to successfully connect to the network.
  9. Exit the modem terminal with the !exit command.
