M3 TR8 - 869 MHz



 SATELLINE-M3-TR8 is a UHF data transceiver module in a lightweight single PCB structure. It is designed to be integrated into a host device. 

The radio module configuration can be done with the SATEL SL-commands or SATEL Configuration Manager -software. 

SATELLINE-M3-TR8 is compatible with widely used SATELLINE-EASy 869 radio modems (see notes below).

The M3-TR8 is a flexible module that will fit into a variety of applications.  It is Pan European approved (with default settings) and is allocated for narrowband telemetry alarm and data transfer applications.  It has a choice of mechanical fastneing and antenna connectors and can be added to any EASy 869 system.

The module is manufactured with an option for 128 bit encryption for secure data transfer and is supplied in a PCB format with RF sheilding ready for installing into your system.

Please also read the following important notes:

It is the recommendation ERC/REC 70-03created by the radio communications committee of CEPT, which sets the technical requirements for the licence exempt use of short range devices on harmonised frequency bands around the Europe. CEPT members (spectrum authorities) have to either follow the recommendation in their frequency management or inform the CEPT radio communications committee about any restrictions. Those national restrictions are listed and attached to the ERC/REC 70-03 document.

License exempt 500 mW sub band

 

The sub band 869.400 - 869.650 MHz on the 869 MHz range is specified for

0.5 Werp (radiated power, in reference with a half wave dipole antenna, 0 dBd = 2.15 dBi). On this band, there are 10 x 25 kHz channels with centre frequencies

The official Satel recommendation is to always use the latest firmware version for the Satel radio modems. Please do find the latest firmware version for the SATELLINE EASy 869 and SATELLINE EASy-M3-TR1 869 products behind this link

 

The latest ETSI specification regarding this matter is dated 5-2012. Since the earlier than 3.63.4 firmware versions for the SATELLINE EASy 869 and SATELLINE EASy TR1 doesn’t have the automatic duty cycle limitation, the duty cycle limitation has been left to the responsibility of the connected hardware as an upper layer application task.

 

Defenition for the duty cycle:

For the purposes of the present document the duty cycle is defined as the ratio, expressed as a percentage, of the maximum transmitter "on" time monitored over one hour, relative to a one hour period.

 

If the upper layer application is not capable of limiting the duty cycle to the ETSI specification requirements, the firmware of the SATELLINE EASy 869 and/or SATELLINE EASy-M3-TR1 869 products shall be updated to the required minimum level, version 3.63.4.

 

Please do note that after updating elder than 3.63.4 firmware version to the latest version, the Subband(frequency range) of the radio modem shall be selected by the user in order to take the automatic duty cycle limitation in use in the radio modem. This task can be executed either from the programming menu via terminal connection, via LCD user interface or via SL –commands with terminal connection.
