I am using the DL06-DD and a F0-2AD2DA-2 reading one Analog Input( 0-5 V Pressure Transducer). If I calibrate it using my laptop everything works. If I switch to 'RUN ' mode nothing changes and everything works fine. BUT ! When I disconnect the serial RJ-45 connection, the pressure settings change by about 10%. I assume this is have some sort of ground problem (even though the laptop is ungrounded) But, I wondered if anyone had seen this exact or similar effect before.
