CONNECTORS
2 lemo00 connectors for connecting the EMAT to the receiver of EMA channel;
2 BNC connectors (one connector for the first pulser, second connector for the second pulser).
1 lemo connector for Encoder connection;
1 power connector;
1 Ethernet connector for transmitting the data to PC;
1 Trigger connector is used either for synchronization between EMA channels, or for EMA channel metrological verification.
