Hi All,
I tested well with CR200 with AVW200 via SDI-12,
But Now and in fact, I need connect CR200 with AVW200 via MUX16/32 and connect CR200 and AVW200 is SDI-12.
I can not create Array two dimensional as exmaple in AVW200 user manual,
Please help me this solve.
We don't recommend the use of the AVW200 when using more than 2 sensors, precisely because of the limited variable space in that logger. Try a CR800 for better results.
However, if you want to proceed, you should install the new Std 4 OS in the AVW200. If you have more than 8 sensors wired to the mux you will not be able to keep all 6 sensor parameters in variables, so you will have to create one 6 element public array and copy the freq and temp from that array to legitimate variables for each sensor.
Also note this new feature in the Std4 OS :
New functionality has been added so that the AVW200 series device can control multiplexers via SDI-12 commands. This allows multiplexers to be connected directly to the AVW200 for SDI-12 measurement scenarios instead of being connected to the Datalogger or other controller. SDI-12 extended commands are used to set the absolute channel address of the multiplexer. The commands are aXMUXaa,ttt! or aXCMUXaa,ttt! (CRC check), where aa is the channel address and ttt is a timeout for how long the multiplexer will remain on and hold the address specified. An address of zero or timeout of zero will reset the multiplexer and zero any previous timeout setting. The timeout can also be updated by sending a new aX! command and selecting a new channel and timeout. In this way, a zero in-between commands isn't required.
Correction:
We don't recommend the use of the *CR200* when using more than 2 sensors...
(We do recommend the AVW200 for much much more than 2 sensors, via mux, etc.)
Also, the implication was that you can't declare multi-dimensional arrays on the CR200. Hence you have to use individual (single-dimensioned) arrays, and even then there are limitations (48 total values).
