Page 25: Maintenance
Maintenance the SDL500. 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. -

That cellular communication does not function below 9.5 VDC, and spread spectrum radio communication does not function below 7.5 VDC. However, if the remote telemetry capabilities cease to work based on voltage requirements, the data logger can still continue to log data provided that the voltage does not drop below 6 VDC or the smallest sensor input power... -

Page 31: Appendix A: Optional Outputs
SDI-12 (Serial Data Interface at 1200 Baud) is a communications protocol developed for instruments that typically monitor environmental data. When configured for SDI-12 output, an SDL500 data logger is set to run as the slave device in a master-slave configuration. This is beneficial when environmental sensors using communication methods not supported by the master device (data logger) must be integrated into a preexisting network. -
Page 32: Modbus Rtu
9BAPPENDIX A: OPTIONAL OUTPUTS With this setup the SDL500 acts solely as an SDI-12 sensor. It does not log data, but rather reports the data that it collects to another data logger. The data is output in a predefined SDI-12 parameter list, which the master device is programmed to interpret. -
Page 33: Appendix B: Uw Receptacle To Fl Cable
The underwater receptacle to flying lead cable is used to pass sensor signals through cabling that has been outfitted with an underwater plug end for connection to an SDL500. It allows a UW connectorized sensor cable to ultimately terminate in flying leads for manual wiring to external power or communication devices. - Page 34 9BAPPENDIX A: OPTIONAL OUTPUTS...
