Every hour the iSIC will run self diagnostic. If during this process an error is identified the iSIC will remain in the boot loader. This can happen if the iSIC has not been used for 10 or more years, experienced a high surge (possibly due to nearby lightning or an Electrostatic Discharge), or had insufficient […]
Overview SDI-12 is a data communications protocol developed specifically for environmental monitoring applications. The motivation to develop SDI-12 began in the 1980s when a group of environmental monitoring specialists started to become frustrated with the complexity of interfacing analog sensors with the data loggers of the time. In addition, these low-power analog sensors were extremely […]
By default, NexSens iSIC and SDL500 data loggers are set in data logger mode. An iSIC or SDL500 logger set in data logger mode can be programmed by and interface with iChart software for data collection and acquisition. iChart can communicate with the logger through direct serial RS-232 connection or via telemetry (radio, cellular, satellite, […]
NexSens iSIC firmware dictates how all functions and procedures are run in iSIC, CB-iSIC, and SDL500 data loggers. New firmware versions are released on a regular basis, so it is important to routinely check for updates. iChart software must be periodically updated in order for the most recent firmware version to be located.

To check the signal strength of a 3100-iSIC cellular modem, use a program called AceManager. The utility is available from the support section of the Sierra Wireless website: www.sierrawireless.com or on one of the Modem Setup Software downloads on the NexSens downloads page. After installing AceManager on the computer, open the program and click Connect. […]
This guide is designed to help fix common problems associated with failed over-the-air communication between a cellular iSIC or SDL data logger and a computer. Cellular communication problems can arise for a number of different reasons, including low power, weak cellular signal strength, improper physical connections, activation issues or data account setup problems. To troubleshoot […]
