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.
myPClab
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.

4. CONNECTIONS
This module operates only when connected to a PC USB bus, using the
included type-A to mini-B cable. The following figure shows all possible input
connections.
myPClab
Warning: Signal wires connected to all inputs should be kept separated from power
wires, and when possible installed inside of grounded electrical ducts.
3.1 Pt100 Wiring
Connections of channel 1 are on terminals 6, 7 and 8. For channel 2
on terminals 2, 3 and 4. Connection with 3 wires from the sensor element to the
module is necessary to cancel the cable resistance error in the measurement.
The 3 wires must have the same length and gauge. To connect a Pt100 with 2
wires, connect terminals 7 and 8 (channel 1) or 3 and 4 (channel 2).
3.2 Thermocouple Wiring
Connections of channel 1 are on terminals 6 and 7. For channel 2 on
terminals 2 and 3. Observe indicated polarity. Cables for thermocouple
connection must have the same thermo-electrical characteristics of the
thermocouple element (compensation or extension cable). Observe that both the
thermocouple and the compensation cable must be connected with correct
polarity. If compensation cable is not used or is not connected with the correct
polarity, large measurement errors will arise.

3.3 4-20 mA Wiring
3.4 0-50 mV Wiring
Connections of channel 1 are on terminals 6 and 7. For channel 2 on
terminals 2 and 3. Observe indicated polarity.
Connections of channel 1 are on terminals 6 and 7. For channel 2 on
myPClab
terminals 2 and 3. Observe indicated polarity.
3.5 0-10 V Wiring
Linear voltage signals from 0 to 10 V can only be connected to
channel 1, terminals 5 and 6. Observe indicated polarity.
3.6 Dry Contact Digital Input Wiring
Digital signals are connected to channel 3, terminals 1 and 2.
The contact connected to digital input must not have any electrical voltage.
ABUS TECHNOLOGIES INC.

3.7 Voltage Digital Input Wiring
Digital signals are connected to channel 3, terminals 1 and 2. Observe
indicated polarity. Voltage levels applied to this channel must be within the
specified limits. See “Technical Parameters”.
5. INSTALLATION
5.1 Recommendation
myPCLab inputs are not electrically isolated from the USB port. Before connecting
myPClab
signals from sensors or transducers, make sure that they are not in contact with any source of
electrical power (wires or conductive surfaces which may get energized). Input channels are not
isolated from each other.

5.3 USB Driver Installation
The following installation steps may be slightly different depending on your PC
configuration and Windows version. Follow the Wizard instructions and use the
following steps and figures to select the correct installation options.
1. Insert the myPCLab CD in the CD-ROM drive.
2. Connect the module to a PC USB port. Windows® will detect the new hardware
and after a few seconds the new hardware wizard will start.
3. The Found New Hardware Wizard will show-up and ask if you want to connect to
Windows Update to get the driver. Select the “No, not this time” and select “Next”.
4. Select “Install from a list or specific location (advanced)” and select “Next”.
myPClab
5. Select “Search for the best driver in these locations” and check option “Search
removable media”. Select “Next”. If the installation files are not in a CD, select
option “Include this location in the search” and type the path for the required files.
6. If a warning message regarding Windows® XP compatibility appears, select
“Continue Anyway”.
7. The myPCLab driver files will be copied to your computer and, when concluded,
a window will show up informing that the wizard has finished installing the
software. Select “Finish”.
8. It is possible that the previous steps repeat a second time for the completion of
installation.
After driver installation, proceed to the next chapter to install the myPCLab
software that provides configuration, visualization, recording and data export.
In future connection of myPCLab modules, it is possible that Windows® prompt
again for the USB driver installation. In this case, the same wizard will be presented.
Follow the above steps, but select option “Install the software automatically
(recommended)”, since the driver files are already installed.
The following figures are examples of Windows XP® New Hardware Wizard. For
Windows 2000® they look different, but the information is the same.

6. CONFIGURATION
Serial Port (COM Port) Assignment
A few seconds after connection of a myPCLab, Windows operating system assigns a COM port
number for communication. The assigned COM port number will not change in future connections to the
same USB port. Users can easily identify and modify the assigned COM port in:
Control Panel / System / Hardware / Device Manager / Ports (COM & LPT)
Select the desired “myPCLab” device, click with the right mouse button and select “Properties”.
Select “Port Settings” and click on the “Advanced...” button. In “COM Port Number” list, select the serial
port to be assigned. Some serial port can be marked as “in use”. Only select one of these ports if you
are sure it is not being used by any other peripheral in your computer.
In some cases, serial port can be marked as “in use” even when the associated device is not in
the computer. In this case, it is safe to assign this port to myPCLab.
