SATELLINE ® -1870
SATELLINE-1870 is the most economical and smallest
member of the SATELLINE radio modem family. Thanks to
its small size, as well as low output power consumption,
the SATELLINE-1870 is particularly well-suited for internal
applications within factories.
LICENSE-FREE FREQUENCY
The SATELLINE-1870 uses the pan-European free 868
to 870 MHz frequency band. This band is divided into
sub-bands according to the output power and duty cycle
allowed for the transmitter. When changing the frequency
the user need not worry about the output power limitation;
the modem automatically sets the output power according
to the regulations. Due to the limited output
power, the radio’s range is 5 kilometres, depending
on surroundings. By using repeater
stations and multiple addresses, the range of
the radio modem network can be extended.
SPECIAL FEATURES
SATELLINE-1870 is compatible with RS-232
interface. The modem can be connected to
a terminal with a ribbon cable or by wiring
a D9 connector. Like the preceding models,
assembling is performed with 2.5 mm screws,
Velcro ® , tape or the DIN-rail with a special
installation kit. The settings of the SATELLINE-
1870 radio modems can be modified by SL-commands
in the normal communication mode or through an external
terminal in programming mode. The software of the
SATELLINE-1870 resides in a flash memory. The flash
memory is easily re-programmable through a programming
device.
