4.6 The USB-MEA256-System
USB-MEA256-System is a high flexible system with integrated amplification, data acquisition,
and analog / digital conversion. Via USB High Speed 2.0 it is possible to transfer a digitally
converted and amplified data stream of up to 252 electrode channels to any data acquisition
computer.
Note: Using a USB hub for connecting the USB-MEA256-System to the computer is not
recommended. The system needs a broad bandwidth for the data transmission. Recording
might not be possible, especially if a second device that sends or receives continuous data
streams, for example a web cam or USB speakers, is connected to the same USB port.

4.7 Connecting the USB-MEA256-System
1. Provide a power supply in the immediate vicinity of the installation site.
2. Place all devices on a stable and dry surface, where the air can circulate freely and the devices
are not exposed to direct sunlight.
3. Set up the computer (with installed MC_Rack program).
4. Set up the MEA256 amplifier as described in chapter "Setting up the Amplifier".
5. Connect the USB output connector to a free USB 2.0 port of the data proceeding computer.
It is not recommended to use an USB hub.
6. Connect the USB-MEA256 via power supply unit to a power outlet of the same electrical system
(connected to the same ground / earth wire) as all other components of the setup, for example,
the computer or shielding.
7. If necessary, connect the system to an external ground.
8. Connect the internal heating element to the temperature controller's output channel (D-Sub9
socket) with the integrated cable. Do not connect the heating element cable to the computer!
9. Turn the toggle switch at the rear panel on.
10. Check the power LED. It should light up as soon as the power line is connected, and the toggle
switch is switched on. If not, check the power source and cabling.
11. Install the MC_Rack program from the installation volume if it is not already installed.
The USB-MEA256-System is a plug and play device. The driver is automatically installed
together with the MC_Rack program.
12. Start the MC_Rack program and select the USB-MEA256-System as the data source.
Please see the MC_Rack help or manual for more details on how to define the data source.
