7.2 Summary

  • The first two connectors (S → N and W → E) are always on the same slots (0 and 1) and are always associated with the channels 0 and 1, aka Ex and Ey.
  • The connectors (Hx, Hy, Hz) are on slots 2, 3, and 4 and if a sensor is detected, are associated with channels 2, 3, and 4.
  • The connectors (MP Hx, MP Hy, MP Hz) are on slots 5, 6, and 7 and if a sensor is detected:
    • are associated with channels 2, 3, and 4 if Hx, Hy, Hz are not detected
    • are associated with channels 5, 6, and 7 if Hx, Hy, Hz are detected
