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 […]
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 […]
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 […]
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, […]
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.
