EC-Lab Technical Notes 21: External device control and recording

Latest updated: August 16, 2021

Introduction

This Technical Note relates to the control and recording of external devices from EC-Lab®. Most BioLogic instruments, controlled by EC-Lab® software, offer the ability for the user to control external devices such as rotating electrodes and thermostatic baths and to record external analog signals through the auxiliary DB9 connector. The user has to configure the “Analog OUT” to control an external device and “Analog In1” and “Analog In2” inputs to record external signals. Our instruments can control and record analog signals from – 10 to + 10 V. Most of the external devices work in a 0 to + 5 V range.
