ProCheck PersonnelSDI-12 Will Not Save You Money

If you’re using SDI-12 to save money, stop now.

Budget to Maintain Your System

That is not to say that SDI-12 is a bad idea. SDI-12 is a very good fit for certain projects. It is not, however, a system that you can install and forget. Money that you save on data loggers and cables will nearly always be spent maintaining the system. If you don’t budget to maintain your SDI-12 system, it will frequently ruin your day, sometimes ruin your data, and possibly ruin your life.

Test the System Once a Week

SDI-12 sensors are wired in series, like Christmas tree lights. If one sensor fails, it will bring down all the sensors on that port. A single sensor failure will have a significant effect on your entire system. That means that you should test the network at least once a week in order to prevent major loss of data. This job requires minimal training if you use the ProCheck to test and troubleshoot, but is essential to running a successful SDI-12 network. If this job is not performed both consistently and correctly, massive loss and/or corruption of data can occur.
