RTM Elster AMCO applicative PFS Coronis Systems
5.4.5.Encoder model detection
(Refers to DR[3] Section 1.0.17; DR[4,5] Section 1.0.16)
RTM Elster AMCO embeds a feature allowing to recognize the encoder model connected.
This feature is performed either when profile selection parameter is programmed with encoder profile value,
or using a dedicated radio command.
RTM Elster AMCO run all encoders drivers and recognizes the connected encoders models.
Once the initialization is completed, RTM Elster AMCO sends back to the command initiator the encoder
model.
Note :
This command has to be performed once the RTM is connected to the encoder, either in the field during
installation phase or during manufacturing phase of the RTM.

(1) : Encoder model description:
Encoder model is 2 bytes long with the MSByte indicating the encoder manufacturer (ELSTER or SENSUS)
and the LSByte indicating the encoder model (example: Scancoder or Invision for Elster AMCO) and this
value takes different meaning depending on the brand.
The table below describes the different encoder models written in field “Encoder model”:
