4 OPERATING MODES
The radio transceiver module has the following modes of operation:
Mode
Ready to receive
from RF
TX
Safe mode
Sleep mode
Power Save
mode
4.1 Safe mode
When a fault has been detected by the Firmware, the module is set to Safe mode. In this mode
the module toggle's the Stat Pin in 250ms interval indicating an Error and reboots the device
after 5s. Transmitting/Receiving is prohibited during malfunction. When connecting to the device
with SATEL Configuration Manager the Error code is shown in pop up box. If the device does not
recover after multiple reboots, please contact Satel Oy.
Satel Configuration Manager can be downloaded from website www.satel.com/downloads.
The version 1.3.15 or newer is compatible with SATELLINE-M3-TR3 and –TR4 radio transceiver
modules.
4.2 Power up / power down scenarios
The transceiver module can be set in four (4) states, "ON", "OFF", "sleep1" and "Power Save".
When power is applied to the module, the module switches to ON state when voltage in
ENA_MOD pin is >1.2V.
The module can be shut down by driving ENA_MOD line to <0.2V.
In the "OFF" state current consumption is only that of leakage current from an LDO (0.34 mA).
In this state all non-essential parts off the module are powered down and all settings / state
information that are not stored in NVM are reset.

Description
Module is searching for the start of a radio
transmission from the RF signal.
The module has found a valid radio transmission and
is receiving data.
The module transmits
Mode is entered when a fault has been detected and
the device has been Rebooted. In safe mode fault
codes can be read from the module.
Will turn the module into a state where it will hold
parts of the radio on, wakeup will take approx. 30 ms
Automatic sleep/wake-up procedure where module
sleeping time is dynamically adjusted to received data
packets. Decreases the power consumption of
complete receiving cycle approx. 30%.
