1. INTRODUCTION
myPCLab is a very compact Data Acquisition tool that connects to a PC via a
USB port and monitors two universal input analogue variables along with one digital
input. From hobbyists to scientists, from simple technical tasks to complex engineering
activities, myPCLab can be an invaluable tool for on-line monitoring and data logging
in school, laboratory research, machine data recording and industrial understanding.
It comes with intuitive and easy-to-use Windows software which plots and
records the data, shows gauges, bar-graphs and digital readouts. The USB port is
accessed as a virtual serial port, which makes myPCLab compatible with SCADA
software with Modbus RTU driver or with any program with ASCII serial
communication.
Multiple units of myPCLab can be connected to the same computer, easily
expanding the number of inputs. The myPCLab software can simultaneously
communicate with multiple modules.
This manual describes software installation and connection of input signals to a
myPCLab module. Instructions on using the software are available on its help system.
