The iSIC plate is designed to hide all the parts that are not meant to be altered by the customer. However, there are a few occasions when it is necessary to remove the plate. For example, parts could fall behind the plate, or the PCB may need to be sent back to NexSens for repair. […]
Switch power is used in data logging applications where power must be conserved. There are two separate implementations of this concept within the iSIC data logger. Sensor Switch Power Sensors plugged into SDL ports P1, T, and A or powered through pin 2 of an iSIC’s digital terminal strip are powered using switch power. This […]
The maintenance switch is a feature in iChart software that can be used for external control of an iSIC data logger. Once the feature has been enabled and a channel has been set, a simple switch controls if the iSIC logs data or not. 1. Open iChart without a current project. 2. From the menu […]
NexSens iSIC data loggers have a default address of 1. When connecting multiple iSICs to a single PC COM Port, unique addresses must be assigned to differentiate between them. This problem occurs most often when using a system of 4100-iSICs. 1. Open iChart without a current project. 2. From the menu bar select Advanced |iSIC | […]
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 […]
