If you need to access the SIM card or install your own, refer to this section.

Account Activation

Contact your wireless carrier to activate this device on your account. They will request the IMEI (modem) and ICCID (sim card) numbers.

Once service has been activated, proceed with the setup steps outlined below.

Windows

Troubleshooting

If you are experiencing any issues with the modem, please screenshot each modem config screen linked below and email them to support@onlogic.com along with your system serial number and details of the issue.

http://172.16.0.1/set_cellular.cgi
http://172.16.0.1/sta_modem.cgi
http://172.16.0.1/sta_network.cgi
http://172.16.0.1/sta_signal.cgi (Click the Advanced button before screenshotting)

Your screenshots should resemble the following examples:

Rebooting the modem

The PC needs to be unplugged from power for a few seconds in order for the modem to shut down. If powering down the PC is not desirable, the modem can be rebooted manually via the web interface.

Navigate to Http://172.16.0.1/sys_reset.cgi (Administrator > Manager > Reboot & Reset)

Factory Reset / Resetting the modem password

If you forget the admin password for the modem, it can easily be reset via a button on the modem. Use the search box above to find the “technical resources” page for your specific model. It will feature disassembly instructions. Follow them to get the chassis open so you can access the modem.

  • With the PC powered on, hold down the reset button on the modem for 6 full seconds. This will trigger a factory reset of the modem.
  • Wait approximately 2 minutes and then reboot the PC. Scroll up to the initial account setup instructions and begin again.

Accessing the internal SIM card

Use the search box above to find the “technical resources” page for your specific model. It will feature disassembly instructions. Follow them to get the chassis open so you can access the modem.

  • Locate the AMIT modem card inside the system.
  • Remove the retaining screw
  • Grab the card by its edges and pull it straight upward.
  • Open the SIM card tray as shown.
  • Remove or insert the SIM by sliding it into the metal clip.
  • Ensure the clip clicks back into place.
  • Be gentle – the SIM card tray is fragile.

  • SIM orientation shown
  • Reinstall the modem ensuring the pin header lines up. Secure with the M2 screw removed earlier.
  • Once the screw has been installed, double check that the pin header is aligned and no pins are sticking out. Misalignment can electrically damage the modem or system.

Using the external SIM slot

Some OnLogic systems come with external SIM slots. The modem will default to the internal SIM slot, so a user must intervene in order to change the active slot.

  • Log in to the web interface and navigate to http://172.16.0.1/set_cellular.cgi (Setup > Network > Cellular)
  • Change “SIM Select” to “External”
  • Scroll down and save
  • Power down and unplug the PC for 10 seconds to reboot the modem. At the next boot, the modem should detect the SIM in the external slot and connect to the cellular network after a few moments.

Port Forwarding

The modem functions as a NAT router. To connect directly to the PC, ports will need to be forwarded. The port forwarding configuration is done via the web interface and is similar to a home router.

  • Navigate to http://172.16.0.1/setportfw.cgi (Setup > Network > Port forwarding)
  • Check the enable box next to “virtual server” and click “add”
  • The example below will open port 8088 and forward it to the PC.
