Radio Modems

Lotus Wireless Technologies offers Radio Modem, Satelline 1870. This particularly suited for internal applications within factories. This satelline 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. Features: low power, low range perfect for indoor applications; operates a license-free frequency band in Europe; RS-232 interface compatible and software programmable. Special features: compatible with RS-232 interface. The modem can be connected to a terminal with a ribbon cable or by wiring a D9 connector. Like with 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 these 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, which is easily re-programmable through a computer.
