NexSens iSIC and SDL500 data loggers can communicate using interfaces such as SDI-12, Modbus RS-485 and RS-232. This process shows how to switch from SDI-12 or Modbus to RS-232 communication in order to allow connection to a PC. 1a. Open iChart without a current project. 2a. From the main menu select Advanced | Terminal… 3a. Select […]
Solar panel kits may be connected to iSIC data loggers to recharge the 12V A01 iSIC battery. Solar charging kits are equipped with a charge regulator to prevent overcharging of the A01 battery and damage to the data logger or connected devices. Use the following process to identify and troubleshoot suspected issues with a solar panel kit. 1. […]
When setting up and troubleshooting a system, it may be necessary to manually enable or disable the logger’s switch power. 1. In iChart, open the diagnostic window by clicking on View | Diagnostic Window. 2. Connect to the data logger. See the appropriate iSIC Data Logger or SDL500 category for instruction on connecting directly to the […]
It may be necessary to reset an iSIC or SDL by manually cycling power. This will allow the system to reboot and can solve various problems. iSIC 1. Open the lid of the iSIC enclosure. 2. Remove both black fuses located to the left of the digital terminal strip. While the fuses are removed, check […]
When set up as a direct connect data logger, The SDL500 submersible data logger can be preconfigured to output environmental data to SDI-12 or Modbus devices. SDI-12 output is typically used for connection to other data loggers, while Modbus output is mainly used for integration into Supervisory Control and Data Acquisition (SCADA) systems. The SDL500 […]
Troubleshooting Follow the procedure below to isolate and resolve SDL500 communication problems. Direct Connect Symptom Possible Cause Corrective Action Cannot communicate with iChart Incorrect COM port or wrong port settings Check the COM port the data logger is connected to and verify the Detail field in the iSIC Setup window reads “COM#, 9600 baud, N81, […]
Maintenance There is very little maintenance required for the SDL500 because it is designed for long-term deployments in harsh and/or submersible applications. Cleaning Any bio-fouling that accumulates on the exterior of the SDL should be cleaned using a soft cloth or soft-bristled brush along with soap and water. Storage While the SDL500 can be stored […]
If a different computer than the one used to create the project is being used to download data, it is likely that the COM port will need to be switched. To determine which COM port the data logger is using, please follow the instructions in Verifying iSIC/SDL COM port. 1. Open iChart with the current project file. 2. Right-click […]
The SDL is outfitted with various ports with different functionality. For the most part these are the same across all models, but the top port differs between a direct connect SDL500 and a telemetry version. Pin Numbering The ports on the SDL bulkheads are Underwater Receptacles (UW-R) that accommodate Underwater Plug (UW-P) connections from various sensors and […]
It is recommended that field deployments be carefully planned. It is best to completely configure the system on a lab bench and test it for a period of time prior to departing for the field. This will ensure a successful deployment and quality data collection. Additionally, it is much easier to troubleshoot problems in the […]
