Galvanically isolated voltage supply and ground. Pin 1, 67, and 68 are connected to the external power
supply, for example, PS40W.
Additional ANALOG IN
Please note that channels 253 to 256 are not used for recording analog data from MEA amplifier.
The 68-pin MCS Standard Connector has 64 possible channels for recording, but MEA amplifier only has
60 channels for recording data. That is why channel 253 to 256 are diverged from 68-pin MCS Standard
Connector D at the front panel and connected to the Analog 1 to 4 at the rear panel. These channels are
used for the additional analog inputs of the
USB-ME256.
