NOTES:
Dump readed with FE with diffrent voltages and Power Adapter (two channel in each readout) to choose for you with is better quality to create layout. Also readed first channel with other reader (I packed them in diffrent directories) - if you require diffrent readout let me know pls.

Dump uploading
