I'm trying to get the measured conductivity from an Oakton CON2700 conductivity meter into a PLC. The unit has an RS232 output for a printer. Instead of connecting to a printer I plan write a script in the machine's HMI to read the stream of ASCII characters coming out of the RS232 port, decode the conductivity value from that, and pass the value to the PLC.
I purchased a cable from Cole-Parmer that was listed in the Oakton manual, but as soon as I connect it to the serial port on my laptop the measured conductivity value jumps by a significant amount and becomes unstable.
Is there anyone familiar with the conductivity meter who can offer any suggestions?
