The temperature and dissolved expansion connector allows for the addition of multiple temperature and dissolved oxygen sensors to a system. See the diagrams below for exact signal pins. Dissolved Oxygen Sensors The dissolved oxygen expansion connector allows for four dissolved oxygen sensors to be added to a system. Connect the positive signal wire to the […]
The digital expansion connector allows for the addition of multiple RS232, and generic digital I/O sensors, as well as a main communication port. See the diagrams below for exact signal pins: RS232 The digital expansion connector allows for two additional RS232 sensors. These ports operate the same as those located on the digital terminal strip. […]
The analog expansion connector allows for the addition of multiple analog input sensors, such as single and differential 4-20 mA sensors, as well as single and differential analog inputs, analog outputs, and temperature sensors. See the diagrams below for exact signal pins. Analog Inputs Pins AD8-A15 can all be used to interface with single and […]
The Federal Communications Commission defines iSIC data loggers as computing devices and requires the following notice. This equipment generates and uses radio frequency energy and if not installed and used properly, may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class A […]
iChart includes advanced tools to view, diagnose and check sensor and data logger functionality. To access these tools, select Advanced | iSIC | iSIC from the iChart menu system. The iSIC Setup dialog box will open: On the first screen, select the COM port, connection method and address of the desired data logger. […]
Internal Battery Reorder Part Number: A01 Recommended Maintenance Frequency: 36 Months (min.) or As Needed The NexSens iSIC data logger comes standard with a 12V, 8.5 A-hr rechargeable sealed lead acid (SLA) battery. This battery will need to be replaced every 24-36 months. Any battery older than 36 months should be replaced immediately. This ensures […]
High gain antennas are used for all deployments with iSIC data loggers using telemetry. The antennas are mounted on the iSIC box. If the antenna is to be mounted on a pole, the mounting pole should have a diameter up to 2-1/2 inches and have a height as high as practical for the application; also […]
AVSS241608 Stainless Steel Enclosure The stainless steel enclosure (Part # AVSS241608) is ideal for NexSens iSIC Data Loggers installed in harsh environments or vandal-prone areas. This enclosure may also be used to house the NexSens 26 A-Hr battery (Part # A03) for projects with power-hungry sensors and heavy cloud coverage. Each enclosure also comes with […]
The NexSens iSIC is powered from an internal battery. The addition of a float charger or solar panel can provide constant re-charging of the battery for prolonged use scenarios. Before data can be retrieved from sensors, power must be supplied to the iSIC. To do so, open the iSIC enclosure and unscrew the battery mounting […]
Electronic circuits are susceptible to voltage surges. The iSIC has on-board transient voltage suppression devices. Connect the ground lug to a proper electrical ground (i.e. earth ground or a properly grounded pipe/metal fixture). For outdoor applications, use the copper wire supplied with the A38 ground kit to connect the ground lug to the rod’s ground […]
