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 […]

The SDL500 supports many standard sensor interfaces and protocols through its UW connector ports, including 1-wire temp string, RS-232, RS-485, SDI-12, pulse count, and both analog and digital input/output devices. NexSens manufactures cables for these common interfaces and can also connectorize user-supplied sensor cables. The sensor bulkhead incorporates ports T, P1, P0, A and D. […]
Reactiviating a Raven XT cellular modem may help resolve communication for a 3100-iSIC modem that can be powered up but is nonresponsive. 1. Unplug the serial DB-9 connector from the iSIC and connect it to an A77 programming cable provided with the data logger. Connect the other end of the programming cable to the computer. […]
iChart Software is used to communicate with the SDL500. Follow the Setup Device Wizard or Installing and registering iChart to install the software. To set up communication, follow the appropriate telemetry steps to establish a connection between the data logger and computer. Direct Connect To establish a direct communication with a computer, first connect the […]
In order to test a cellular modem is functioning properly, a few simple steps can be taken. 1. Connect an antenna to the modem. 2. Connect a RS-232 cable from the modem to your computer. Note: A USB adapter may be necessary on newer computers that do not have a serial port. 3. Supply 12V power to […]
In order to update a SDL’s firmware using a UW-USB-485P communicaiton cable, the communication protocol must be changed to RS-485. 1. Establish temporary RS-485 communicaiton with the device by following the steps in the Direct connection with an SDL500 via RS-485 article. 2. From the menu bar select Edit | Preferences. 3. Switch to the GUI tab. 4. Check the “Enable […]
