2 Introduction
2.1 About this Manual
It is assumed that you already have a basic understanding of technical and software terms. No special skills
are required to read this manual.
If you are using the device for the first time, please read the Important Safety Advice before installing
the hardware and software, where you will find important information about the installation and first
steps.
The device and the software are part of an ongoing developmental process. Please understand that the
provided documentation is not always up to date. The latest information can be found in the Help.
Check also the MCS web site (www.multichannelsystems.com) for downloading up-to-date manuals
and help files.
2.2 Welcome to the USB-ME-System
The USB-ME-System is a stand-alone solution for acquiring data from up to 256 channels. It can replace
the internal computer hardware MC_Card. The analog input signals are acquired and digitized by the
USB-ME-System and the digital electrode signals are transmitted to the connected computer via universal
serial bus (High Speed USB 2.0). Thus, it is possible to use any computer for data processing. Recorded data
are graphed, analyzed and reviewed with the powerful and easy-to-use Multi Channel Suite, the newest
software package from Multi Channel Systems MCS GmbH or the well-proved MC_Rack program. You can
export the data in standard formats.
The USB-ME-System supports up to 256 channels with an amplification factor 1 that means no
amplification, data acquisition only.
It is a high flexible system: You can connect, for example, four MEA60-Systems via MCS high grade cables
or two MEA120-Systems or ME-Systems in different configurations or whatever comes with 68-pin MCS
standard connectors. Please see "Microelectrode Array Systems" and "Microelectrode Array USB-Systems"
for more information. You can stack several USB-ME-Systems but you need a separate data proceeding
computer with software for each system.

3 Software Installation
Please check the system requirements before you install the data acquisition software. MCS cannot
guarantee that the software works properly if these requirements are not fulfilled. Please see the software
help or manual for more information. It is recommended that you check the MCS web site for software
updates on a regular basis.
The USB-ME-System is a plug and play device. The driver is automatically installed together with the
Multi Channel Suite or MC_Rack program. It is easier to connect the USB-ME-System first to the data
acquisition computer and then install the software.
Important: Please make sure that you have full control over your computer as an administrator. Otherwise,
it is possible that the installed hardware does not work properly.
3.1.1 System requirements
One of the following Microsoft Windows ® operating systems is required: Windows 8 and 7, VISTA
or XP (English and German versions supported) with the NT file system. Other language versions may
lead to software errors. Windows 8 is essential for the Multi Channel Suite software.
Hardware: (Not required for offline analysis or demo mode). The data acquisition board USB-ME-System.
If no USB-ME-System is present, MC_Rack opens in a simulation mode. A computer with low
performance may lead to performance limits more often; therefore, MCS recommends an up-to-date
computer optionally with a separate hard disk. Please note that there are sometimes hardware
incompatibilities of the USB-ME-System and computer components; or that an inappropriate computer
power supply may lead to artifact signals. Please contact your local retailer for more information on
recommended computer hardware.
Important: You need to have installed the latest USB-ME-System driver to operate the USB-ME-System,
which is automatically installed with the software. The installation may be invalid if the USB-ME-System
does not respond. Please contact Multi Channel Systems or your local retailer in this case.
3.1.2 Recommended BIOS settings
Recommended operating system settings
The following automatic services of the Windows operating system interfere with the data storage on the
hard disk and can lead to severe performance limits in MC_Rack. These routines were designed for use on
office computers, but are not very useful for a data acquisition computer.
 Turn off Screensaver.
 Turn off Windows Indexing Service. Only important for data hard drive.
 Manual management of automatic Windows Update.
 Power Options: Power scheme: Never turn off monitor, hard disk and system standby.
 It is also not recommended to run any applications in the background when using the software. Remove
all applications from the Autostart folder.
 Be careful when using a Virus Scanner. These programs are known to disturb the software, and even data
loss may occur.
When using an USB-ME-System it is recommended to connect a high performance computer with a
separate hard disk for program files and data storage. The provided possibility to use up to 256 channels
with up to 40 kHz needs high memory capacity. Please remove data and defragment the hard disk regularly
to ensure optimal performance.

3.2 Multi Channel Experimenter 
Double-click the Multi Channel Experimenter icon or select Multi Channel Experimenter from the "Start"
menu. The program starts. The main window opens automatically: "Multi Channel Experimenter (Instance:
1)". It is possible to open up to four instances in parallel. Operation is independent for each instance.
This is your virtual rack configuration in the "Experiment Setup" window, which is blank after program
start. On the left side five classes of instruments are provided: "Data Sources", "Recorder" and
“Stimulators" are hardware components. The virtual instruments available up to now are divided in
"General" and application specific "Neuro".
The header of the dialog contains five buttons: "Start DAQ", "Start Recording", "Load Experiment" and
"Save Experiment" in the main toolbar on the left and the "Menu" button on the right. In the bar down
under the "Recording Time" and the "DAQ Time" are registrated.

Building a Rack
It is very easy to build a rack: Please click onto the button of the desired instrument and move it via drag
and drop from the left to the right side of the main window!
It is also easy to connect the instruments: Please click onto one of the symbols on the lower part of an
instrument button to connect this output port via drag and drop with the input port (symbol on the upper
side) of the target instrument. Please read the next chapter.
