Hi. I hope to get some help here.
I have some soil water&temperature probes （TDR） in my lab. The wring connection of the probe is RS485. Four lines in the leading wire are used to connect to anode (12v DC, red) , cathode( black), 485-A (yellow) and 485-B (blue) ,respectively according to the user manual. I am not clear whether the 4 lines can be connect directly to cr1000 terminals. what is the correct conneting mode of the probes to CR1000? the right data collection program for the probes in cr1000 is ?
The CR1000 does not have RS-485 circuitry integrated. An adapter such as a SDM-SIO1A will be needed.
