Setting Up and Connecting the USB-ME128-System
USB-ME128-System is a high flexible system. Via MCS high grade cable it is possible
to connect, for example, one MEA1060 amplifier or two MEA1060 amplifiers or
a ME-Systems with at least 128 channels to the 128 analog inputs.
Example: The description of the installation includes an example setup with a MEA1060
amplifier two MEA1060 amplifiers 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-ME128-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.
5.2.1 Front Panel
5.2.2 Power LED
The Power LED lights up when the USB-ME128 is connected via power supply unit to the power
supply system.
5.2.3 Analog Inputs A and B
The 68-pin MCS standard connectors on the front panel of the device are analog inputs
for the data streams coming from the connected amplifiers. The connectors on the front panel
labeled with A and B communicate with the digital Trigger Inputs 0 and 1. The MCS high grade
cables (C68x1M or C68x3M) with 68-pin MCS standard connectors on both heads are used to
connect MEA or ME amplifiers to the USB-ME128 for analog data transfer. Please read chapter
"Pin Layout" (68-pin MCS standard connector) in the Appendix.
5.2.4 Digital Trigger Inputs
The Digital Trigger Inputs 0 and 1 need Lemo coaxial cables with BNC connectors for the
MEA amplifier at one head and Lemo connectors at the other head for the USB-ME128 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.
