Other identifiers
 A 9-pin M23 connector always means an 11 µApp interface.
 Encoders connected to the encoder inputs of EXE interpolation electronics are always
11 µApp encoders.
 Encoders connected to the encoder inputs of IBV interpolation electronics are always
1 Vpp encoders.
Note
The identification of the interface type applies to standard HEIDENHAIN encoders.
Deviations from the designation structure are possible (in particular with customer-specific
encoders).
Note
For encoders with D-sub connectors no conclusions can be made about the interfaces.
