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 […]
NexSens 4100-iSIC and SDL500R data loggers communicate using 900 MHz spread spectrum radio technology. This telemetry has a limited range, which can be extended by using one or more repeaters. To setup a radio data logger as a repeater, follow the steps below. 1. Open iChart without a current project. 2. If the update will […]
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 […]
When a 4100-iSIC or SDL500R data logger is powered, it defaults to TTL mode for connection via the 900 MHz radio module. There are times when it is convenient to connect directly to iChart. For example, while configuring, calibrating or updating the firmware of an iSIC. To interface with the logger via RS-232 serial connection, […]
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, […]
