The iSIC data logger’s DIO0 and DIO1 lines are programmable digital input/output signals. In revision 6, the signals are 5V logic and can tolerate up to 6V. In revision 7, the signals are 3.3V logic and can tolerate up to 35V indefinitely. The most common use of these lines is to use them to drive […]
Many iSIC data logger commands can be executed remotely. However, this requires editing the .INI file, which can have hazardous effects if done incorrectly. Remote commands should only be used for very specific and deliberate purposes. 1. Open iChart without a current project. 2. From the menu bar select Edit | Preferences. 3. Switch to the GUI tab. […]
NexSens iSIC data loggers can connect to iChart software directly, or through the following telemetry options: analog phone modem, cellular modem, spread spectrum radio, Ethernet, or Wi-Fi. When setting up a new system or testing new configurations it is essential to establish and confirm communication between the iSIC and the PC. 1. Open iChart without […]
Communication issues develop for a number of reasons, including poor signal strength, low battery, damaged hardware, loose connections, or excess moisture inside connectors or enclosures. If loss of real-time data, intermittent performance, or signal failure occurs, the first troubleshooting step is to verify that the iSIC is powered. 1. Disconnect the iSIC from all external […]
iSIC and SDL500 data loggers have optional Power Management settings that can be used to conserve power for systems with a high power demand or when solar charging and battery power are limited. The Power Management settings are implemented through iChart software. Power Management allows users to turn off power-hungry devices such as cellular modems […]
All iSIC data loggers are equipped with a DB-9 serial connector for direct-to-PC communication through iChart software. There are times when it is convenient to connect directly to iChart. For example, while configuring, calibrating or updating the firmware of an iSIC. 1. Open iChart without a current project. 2. Use a DB-9 data cable to […]

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 […]
Overview Electrical grounding is a commonly misunderstood and improperly implemented component of environmental monitoring systems. Systems that do not use electrical grounding components can experience either complete system failures or intermittent problems that are hard to diagnose. However, just using grounding devices is not enough. Improper installation of electrical grounding components can render the components […]
