iSIC

In iChart, go to the Advanced | iSIC | iSIC menu. The iSIC Setup dialog box will open:     The first screen gives the iSIC connection options. Enter the COM port and connection method of the desired iSIC as well as the iSIC Address. For example, if trying to connect to a 2100-iSIC with […]

Single-Ended (Non-Isolated) 4-20mA Sensors Connect single-ended 4-20 mA sensors to the internal analog terminal strip. A diagram of this is shown below:   Pins AD0 through AD7 can all be used for connecting 4-20 mA sensors. Eight 4-20 mA sensors can be connected at the same time using these pins on the analog terminal strip. […]

Environmental measurements can be determined by reading a simple voltage output from a sensor. The voltage level is proportional to the measurement parameter. Every NexSens iSIC ships standard with (8) analog channels. (8) additional analog channels can be added with a factory installed analog expansion. The iSIC can measure voltages up to 2.5V (i.e. 0-1V, […]

If an SDI-12 sensor reading shows -99999.99 or -100000 in iChart, it indicates that there is a communication problem between the data logger and the SDI-12 sensor. In this situation, there are several possibilities: 1. Insufficient power supply 2. Loose wiring between the logger and sensor 3. The data logger SDI-12 interface is not functioning […]

Multiple SDI-12 Sensors can be wired to the same digital terminal strip. Up to ten SDI-12 devices can be connected to the SDI-12 pin on the iSIC Data logger. Any NexSens iSIC data logger can “pass-through” telemetry and allow SDI-12 commands to be sent directly to the sensor. Because each sensor in a multiple SDI-12 […]

RS232 In addition to the single RS232 port located externally on the iSIC via the MS8 connector, three RS232 ports are available on the internal Digital terminal strip. Ports 1, 2, and 3 are available for use. To connect your RS232 sensor to the iSIC, open the enclosure, unscrew the correct pins on the terminal strip, […]
