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.
