SATELLINE®-3AS 869 MHz

New Frequency Band

According to the recommendationCEPT/ERC/REC 70-03 new commonspectrum allocations for Short RangeDevices (SRD) have been taken into usein the countries within the CEPT (TheEuropean Conference of Postal and Tele-communications Administrations). The868 ... 870 MHz band is divided into sub-bands according to transmit power (max0.5 W) and duty cycle allowed for trans-mitter.

Satel’s newest version of SATELLINE-3AS uses the 869.4 ... 869.65 MHz fre-quency band. This band has 10 separate25 kHz channels for a maximum powerof 0.5 W ERP* and 10 % of transmitterduty cycle. Transmitter duty cycle andthe maximum constant transmission time(max 36 seconds) must be controlled bydata terminal equipment. Other features

of the SATELLINE-3AS 869 MHz versi-on are equivalent with the older 450 MHzversion. The receiver of the SATELLINE-3AS/869 has been designed to meet therequirements of receiver class 1 accordingto EN 300 220-1 standard. High perfor-mance of the receiver enables it to beused in an environment with potentiallyinterfering transmitters.

*ERP means antennas effective radiatedpower relative to a half-wave dipole in acertain direction. 0.5 W ERP is achievedwith 0.5 W fed to a dipole antenna, or forexample 0.25 W fed to an antenna with 3dBd ( 5,2 dBi) gain.

New Frequency Version of Satelline-3AS

SATELLINE-3AS is a half-duplex radio modem suitablefor a variety of data transfer applications, in particularones demanding high speed and precision. In additionto the maximum data speed of 19.2 kbps at channelspacing 25 kHz SATELLINE-3AS offers a number offeatures and functions. 869 MHz is a new frequencyversion of SATELLINE-3AS for narrow band telemetry,alarms, data etc. applications.

The SATELLINE-3AS software includes a selectableerror correction, which improves the functioning ofthe radio modem under interference.

SATELLINE-3AS is compatible with the interfacetypes RS-232, RS-422 and RS-485. Without changingthe hardware all the parameter settings of the radiomodem can be modified through the interface froma PC.

The model SATELLINE-3ASd is equipped with aLCD display of its own, which facilitates programmingof the radio modem.

A versatile radio modem witha number of user’s choices

The SATELLINE-3AS radio modemconsists of a synthesized transceiver anda modem board, packed in a compactaluminium case. The model SATEL-LINE-3ASd is additionally equippedwith a user interface LCD display.

SATELLINE-3AS exhibits a maxi-mum data speed of 19.2 kbps. Withinthe new frequency range 869 MHz thereis 10 separate 25 kHz channels. SATEL-LINE-3AS is compatible with the threemost widely used standard data interfacesRS-232, RS-422 and RS-485. The radiomodem can be connected to a terminalwith any one of these interfaces. Thedata speed is selectable within the limits300...38 400 bps.

In the SATELLINE-3AS the errorrate is minimized by means of advancechecking and correction of the data pac-kets. In Forward Error Correction (FEC),the data packets are split in severalblocks. The radio modem adds correctioninformation inside the blocks duringtransmission.

The setting of operating parametersand selection of mode and function isperformed with a PC through the RSinterface. The model SATELLINE-3ASdis equipped with a LCD display and fourpush buttons. In addition to changingthe setups of the radio modem, the dis-play is used for testing operating condi-tion of the radio connection betweentwo stations.

The software of the SATELLINE-3AS resides in a flash memory. The up-dating of the radio modem programs isentirely software-based. The flash me-mory is re-programmable through an RSinterface.

SATELLINE-3AS can be operatedat a voltage range of 9...30 V. In practicethis means that the radio modem isadaptable to both 12 Vdc and 24 Vdcsystems.

Auxiliary functions

With the radio modem in the Test Mode,the state of the radio connection can betested by means of data packets.

The Data Transfer mode of theSATELLINE-3AS includes a CommandProgram function in which the radiochannel and addresses can be changedon-line from the serial port of the radiodata modem. The changes are effectedby means of a specific programming pac-kage (SL command), which is entered

amidst ordinary data.Note! Propagation of radio signals at

higher frequencies differs from the pro-pagation at lower frequencies. The ruleof thumb is that when you double thefrequency you cut the communicationdistance in half. So compared to the 450MHz version the maximum communica-tion distance is half when SATELLINE-3AS 869 MHz version is used. By usingproperly designed antenna installationsor repeater stations required communi-cation distances can be achieved.
