Call php mobile/system/ADU-11e/create_system.php and I should generate a ADU-11e system with 8 channels.
Location should be $HOME/tmp/sqlite_db_created.

Naming convention has changed to MTH5; sample_freq(uency) is now sampling_rate, and float values are now int (Hz).
site -> station
filter mtx4 -> 4
So watch out please.

4.1 Scope

Understanding the databases structure on an advanced level.

NoteMTH5

this new interface already uses the naming conventions of MTH5

• station(s) [string]
• sample rate(s) [int, Hz]
• duration(s) [int, s]
• chopper on/off [int 1, 0] to be understood as LF/HF mode [of the coil]

4.2 Definitions

• Sensor: item “outside” the ADU, e.g. electrode, coil, clamp.
• Slot: the physical slot (connector, MP == multi purpose)
  
  • E_x 0
  • E_y 1
  • H_x 2
  • H_y 3
  • H_z 4
  • MP H_x 5
  • MP H_y 6
  • MP H_z 7
• Channel: that is a (sensor + slot) = the data stream, e.g. E_x, E_y, H_x, H_y, H_z, MP H_x, MP H_y, MP H_z.
  Channel number must not necessarily be the same as the slot number!
  For technical details ref.: ADC and Slots Flow.

4.3 Auto Detection

slot 0	slot 1	slot 2	slot 3	slot 4	slot 5	slot 6	slot 7
false	false	true	true	true	true	true	true

The mobile web interface will let you configure E 0 & 1, e.g. E_x, E_y of J_x, J_y (currents).
Slots > 1 are detected and treated as H (magnetic) by default.
