Rs232 ultrasonic sensor to cr300 series

bell2319 Oct 17, 2018 05:28 PM

How can I wire an ultrasonic sensor to a cr300 series data logger? I'm finding it difficult because it cant produce data. Also, I cant connect it to the RS232 port of the logger because it will be used to connect a radio as the communication ofthe logger to the server.

The answer to your question is entirely dependent upon the protocol(s) used by the sensor to report data.  If, for instance, the sensor reports its data using SDI-12, it would be connected to either the C1 or C2 ports and your program would use the SDI12Recorder() instruction to trigger measurements and to poll data.   If, on the other hand, the sensor uses a different protoocol using RS-232 or RS-485 at the physical layer, you would need to use both C1 and C2 as serial I/O for the datalogger program.

Thank you for the tip for this topic.  The protocol that we will be using is RS-232. The sensor to be used is SENIX Toughsonic50-RS232 and we will setup it as remote station via vhf radio. It is possible right?  Thank you very much for the help.

Also just an additional inquiry one set of this read zero values sometimes.  What could be the probable cause?
