USER MANUAL
Scavenger Transmitter Module
STM 330 / STM 331 STM 331U / STM 332U / STM 333U
(Stepcode DE and later)
3.9.2
Configuration via serial interface
Via the programming interface the configuration area can be modified. This provides a lot
more configuration options. Values set via serial interface override hardware settings!
These settings are read after RESET or power-on reset only and not at every wake-up of
the module!
The interface is shown in the figure below:
EnOcean provides EOPx (EnOcean Programmer, a command line program) and Dolphin
Studio (Windows application for chip configuration, programming, and testing) and the
USB/SPI programmer device EOP 350 as part of the EDK 350 developer´s kit.
The configuration page of DolphinStudio is shown in the figure below.

Wake up cycle
See section 3.9.1 Value can be set from 1 s to 65534 s
Redundant
Retransmission cycle
See section 3.9.1 Min…Max values for random interval
If Min=Max -> random switched off
Threshold values for
inputs
(transmission of telegram if
threshold value exceeded)
No
The default values are:
Temperature measurement: ±0.5 K
Set point measurement: ±10 digits
Edge of wake pin change
causing a telegram trans-
mission
No
Every change of a wake pin triggers a wake-up.
For both wake pins it can be configured indi-
vidually if a telegram shall be sent on rising,
falling or both edges.
On STM 330 / STM 331 only the wake1 pin can
be configured. The wake0 behaviour is fixed
due to mode switch between secure and en-
hanced mode.
Manufacturer ID and EEP
(EnOcean Equipment Profile)
No
Information about manufacturer and type of
device. This feature is needed for “automatic”
interoperability of sensors and actuators or bus
systems. Unique manufacturer IDs are distrib-
uted by the EnOcean Alliance.
