70 4 End marker latitude S32 Degrees x 1e-7 (see Marker triggered definition)
74 4 End marker heading S32 degrees x 1e-5 (see Marker triggered definition)

Note:

  • Trigger rule 1 is always used for start condition 1
  • Trigger rule 2 is always used for start condition 2
  • Trigger rule 3 is always used for end condition 1
  • Trigger rule 4 is always used for end condition 2

Previously this relationship was set by the indexes in old config msg 189, but in practice it was never varied from the above and hence the indexes have been abolished.


Triggered test flags:

Bit 0: Enable analog output
Bit 1: Enable pulse output
Bit 2: Enable distance output (no longer used, but retained in case required again)
Bit 3: Subsequent start triggers reset test (no longer used)
Bits 4->7 Currently unused
