RadioMetrix Ltd has launched a new range of narrow-band multi-channel (LMT2 and LMR2) the provision of multi-channel OEM, power conservation, reliable data link. This combination of transmitter and receiver are well suited for low-power broadband when the modules do not have the range, or low-cost multi-channel is needed, but the functionality of the RF.
Narrow-band multi-channel transmitter and receiver pairThe devices can comm
unicate at distances greater than 500 meters (on the proper use of antennas), the publisher of the sport with an output of +10 dBm (10mW) and the receiver sensitivity of - 120dBm (for 12dB SINAD). The transmitter / receiver combination can be configured to operate at a frequency of 433 MHz ISM band (frequency as other alternatives available, including the UK, 458MHz band). Both devices are managed from a 3.1 - 15V supply, the issuer of the current consumption of 34mA and its partners should 20mA. The maximum speed of the data is 5kbp / s for standard versions (a quasi-DC data recovery circuit improves performance with unbalanced information asynchronous).

The maximum speed of the data is 5kbp / s for standard versions (a quasi-DC data recovery circuit improves performance with unbalanced information asynchronous). The LMT2 and LMR2 are fully re-programmable via RS232 interfaces, a total of 32 discrete channels are programmed into the unit (of which 16 can be selected through a parallel port). These modules are suitable for targeting a wide range of tasks, including handheld terminals, equipment for environmental monitoring, barcode scanners, data loggers, data from the vehicle or download industry telemetry and remote access and security high-end systems. The LMT2 has a 33mm x 23mm x 9mm fully screened package, while the counterpart is 45mm x 23mm x 9mm. Both units are compatible pin-out, creating a common layout for one of them. These radios are designed to conform to both EN 300 220-3 and EN 301 489-3 EMC standards.
