Loading a template into a cellular modem is required for a 3100-iSIC or SDL500 cellular data logger to communicate properly with iChart software. In most cases, NexSens writes the modem template and provisions the modem prior to shipment. However, in some cases, it may be necessary for a user to write the template to a new modem or a modem that has been set to factory defaults.

1. Download the appropriate modem template file from the NexSens Downloads page or contact NexSens to obtain the appropriate file.

2. If using a Sierra Wireless Raven XT modem, use a USB cable and the modem’s mini USB port to connect the modem to a computer. If using a Sierra Wireless LS300 modem, use an Ethernet cable to connect the modem to a computer.

3. Connect the cellular antenna and power the modem. Wait 1-2 minutes for the modem to locate a signal.

4. Open a web browser and type the default IP address into the address bar as follows:
