5 USB-ME-Systems
5.1 Setting Up and Connecting the USB-ME64-System
USB-ME64-System is a high flexible system. Via MCS high grade cables it is possible to connect,
for example, a MEA60-System or ME-Systems with at least 64 channels to the 64 analog
inputs.
Example: The description of the installation includes an example setup with a MEA1060 amplifier
without blanking circuit.
Warning: Please read the separate manuals of all devices before installation, especially
the warnings and safety information. Make sure all devices are switched off before you
connect them to the power supply. Damage to the devices and even fatal injuries may result
from improper installation or use.
Note: Using a USB hub for connecting the USB-ME64-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.
5.1.1 Front Panel
5.1.2 Power LED
The Power LED lights up when the USB-ME64 is connected via power supply unit to the power
supply system.
5.1.3 Analog Input A
The 68-pin MCS standard connector on the front panel of the device is an analog input
for the data stream coming from the connected amplifier. The connector on the front panel
labeled with A communicates with the digital Trigger Input 0. The MCS high grade cables
(C68x1M or C68x3M) with 68-pin MCS standard connectors on both heads are used to connect
MEA or ME amplifier to the USB-ME64 for analog data transfer. Please read chapter "Pin Layout"
(68-pin MCS standard connector) in the Appendix.
5.1.4 Digital Trigger Input
The Digital Trigger Input 0 needs Lemo coaxial cables with BNC connectors for the MEA
amplifier at one head and a Lemo connector at the other head for the USB-ME64 device
(C-BNC-Lemo). The Digital Trigger Inputs accept TTL pulses from any device, for example,
signals from a stimulus generator STG for triggering the system, and they control the recording.
