Problem: PicoLog data suddenly dropped from 0.3 to -1.5 though the panel display is 0.3. I have to power off the machine and shut down picoLog, then restart to solve this problem. It happens very often and disturbs my normal tests.
You mentioned if the voltages on the RS232 is not supplying enough voltage then it could fail to respond intermittently.
There are 25pin connector on ADC16 panel. Pin 1: -5 v, Pin 2: +5
and from Pin6 to pin 13 are channels 8 to 1. Is this input voltage or supplying voltage for RS232?
RS232 has 9 pins:
o o o o
o o o o o
Could you please tell me which pins are 4, 5, 7? You said Pin 4=-7v,pin 5=GND, Pin 7= +7 v. Can I use muiltimeter to measure them? And how?
Thank you very much.
