LX20BGGPRS/SMS/PSTN/2G/3G transmitters. Telephone line simulation and DTMF receiving. SIA/Contact ID protocols via telephone input – integrated SMA connector – possibility of adding a GSM antenna/radio receiver for remote control

The LX20 succesor - LX20B transmitters are modern, microprocessor devices used for the real time packet data transfer through GSM networks via GPRS and SMS channels.

LX20 transmitters are used mainly as the transfer module from security systems. Devices co-operate with all of the most popular alarm systems. Usage of the packet data transfer allows to reduce the alarm system functioning costs.

The possibility of LX20 application is much broader. They can be applied everywhere where there exists a necessity to collect information and send them over distance in real time. Thanks to the intuitive and flexible configuration they may be applied in systems with specific requirements ex. energy consumption measurements, vending machines control systems, meteorological station, elevator systems and many others.

LX20B transmitter provides the highest security of data transmission through up to transmission channels: / GPRS / UMTS / /HSPA (3G) / SMS. The primary purpose is to use the device as a security systems transmission module. LX20B transmitter works with all most popular alarm systems. The addition of a packet data transmission (GPRS / UMTS / HSPA), can reduce the cost of the alarm systems. This device provides an opportunity to send text messages to private mobile phones.

An advanced encoding methods like a 256 bytes encoding key and AES (Advanced Encryption Standard) provides for security of data transmission. As a result reception of this transmission is possible with OSM.Server monitoring receiver system. Furthermore there is possibility to transmit not coded messages that are to be comprehensible by reception solutions and also by GPRS Server software.

LX20 transmitters are offered independently or in sets with plastic casing, AC adapter and accumulator. In addition we also offer OSM.Server Monitoring System Receiver - a program, which enables to receive data sent by transmitters over GPRS and SMS channels.
