Satelline-2ASxE
A versatile PC Compatible UHF Radio Data Modem
Synthesized radio, +/- 1 MHz tuning range
Channel spacings 12.5/20 or 25 kHz
Wide operating voltage
High sensitivity
Programmable settings
Test mode
Data speed 1200...9600 bit/s
Meets Strict European Standard
The SATELLINE-2ASxE complies with the European Specification ETS 300 113. The user has a
few available alternative channel spacings, 12.5 kHz and 20 kHz, or the 25 kHz channel
spacing, depending on the model. The frequency band in use is the center frequency +/-1 MHz,
which means that the number of possible radio channels with channel spacing 12.5/20 or 25 kHz
is 160/100 or 80, respectively. The maximum data speed is 4800 bit/s with channel spacings
12.5 and 20 kHz, and 9600 bit/s with the 25 kHz channel spacing.
Ample Selection of Modes and Functions
SATELLINE-2ASxE incorporates programmable software with a large number of functions and
settings. The operating status of the radio modem is controlled through a table of
parameters, which are conveniently set from a PC through an RS-232 interface. The radio
modem operates usually in one of three operating modes: In the Data transfer mode it is
used for either transmitting or receiving. The selection of functions and setting of the
parameters is performed with the radio modem in the Programming mode. In the Test mode,
the condition of a radio connection can be tested by means of data packets or the
carrier wave.
Excellent Coverage
The output power of the transmitter is 1.0 watts, and the sensitivity of the receiver
-115 dBm, which gives an operating range of 2 to 40 kilometers, depending on local
conditions as well as the gain and installation height of the antennas.
Satelline-2ASxE Special Features
Using Addresses
The radio modems included in a local area network can be given addresses,
for the purpose of identification. Addresses, either the same or different, can
be attached to both the transmitting (Tx) and receiving (Rx) module of the radio modem.
Repeater Function
In case there is a need to extend the coverage of the radio modem network,
the SATELLINE-2ASxE radio modem can be used as a repeater station. In the repeater
function, it receives a data packet (max length 135 bytes) and transmits it
immediately further.
Handshaking not Necessary
The SATELLINE-2ASxE is capable of two-wire operation, which means that
it can be used together with terminals which do not support any kind of
handshaking, provided that the radio channel is free and the length of the data
packet does not exceed 1 kbyte. For maximum reliability, it is however
recommended using the CTS handshaking where feasible.
Application Domain
SATELLINE-2ASxE is primarily used for various local area data communications
applications in industrial and urban environments. Thanks to its small size
it can be easily mounted and integrated into fixed as well as mobile terminals.
The RS-232 interface facilitates easy connection to the customers' terminals
and systems.
Point to Point
By means of two SATELLINE-2ASxE modems a connection between two points can
be easily set up. SATELLINE-2ASxE is compatible with the Model SATELLINE-2ASxm2
radio modem.
