SDI12 instructional videos on YouTube
YouTube is a great resource for people who like to see things in action rather than reading the product manual. Here are a few references that we’ve found useful for demonstrating SDI-12 features or functionality.
SDI12 Watch or Sniffer mode
Some dataloggers (such as Campbell Scientific’s CR200X, CR300, CR800, CR1000, CR6, OTT dataloggers and NR Systems SDI12 verifier) support SDI12 watch or sniffer mode. This is a terminal mode that allows you to see the raw SDI12 commands between the datalogger and the instrument
SDI12 Transparent Mode
Similar to sniffer mode but instead of watching the traffic between the datalogger and the sensor, you can enter commands manually to talk directly to the sensor. This is a useful technique for verifying communications, particularly for changing the address. Entering ?! asks for the address of any sensor connected. Once known, the address may be changed with the aAb! command (where a is the current address and b is the new address). These commands are normally only used for fault finding or configuration so transparent mode is easier than writing a custom program.
