5.3.1 Front Panel
5.3.2 Power LED
The Power LED lights up when the USB-ME256 is connected via power supply unit to the power
supply system.
5.3.3 Analog Inputs A, C, B, and D
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 left side of the front
panel labeled with A and C communicate with the left digital Trigger Inputs 0 and 2. The 68-pin
MCS standard connectors on the right side labeled with B and D corresponds with the digital
Trigger Input 1 and 3. The MCS 68-pin 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-ME256
for analog data transfer. Please read chapter "Pin Layout" (68-pin MCS Standard connector) in the
Appendix.
5.3.4 Digital Trigger Inputs
The Digital Trigger Inputs 0, 1, 2 and 3 need Lemo coaxial cables with BNC connectors for the
MEA amplifier at one head and Lemo connectors at the other head for the USB-ME256 device.
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.
