In order to connect a sensor to the iSIC, the output voltage must be cut down to 2.5V. In order to accomplish this, two resistors must be utilized to act as a voltage divider. The diagram below demonstrates the proper connection for a 5V sensor. Note: ADx is any single ended iSIC analog inputs […]

Removing an iSIC Mounting Plate
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. […]
Power Management – Switch Power
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 […]
Directly Connecting to a 5100-iSIC Data Logger
To directly connect to a 5100-iSIC data logger, simply unplug the Ethernet modem RS-232 cable from the iSIC data logger’s DB9 port and plug in an RS-232 cable directly connected to a PC running iChart software. If the 5100-iSIC is already setup in iChart, select it from the Navigation Panel and then right-click […]
5100-iSIC Connecting Directly to the Ethernet Modem
To establish communication with a 5100-iSIC data logger, the Ethernet modem must be configured for the local network by setting the static IP address, gateway, netmask, and other relevant parameters. Configuration of the Ethernet modem requires direct connection to the device’s serial port. To connect to the Ethernet modem’s serial port: 1. Disconnect the modem […]
Controlling an iSIC Using a Maintenance Switch
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 […]
Verifying the Address of an iSIC or SDL500 Data Logger
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 | […]
Checking the Status of an iSIC DIO Signal
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 […]
Resetting an iSIC or SDL500 in iChart
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. […]
Confirming Connection Between an iSIC and a Computer
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 […]
