Radiometrix says that its 9600 baud TDL2A radio modem module is, for the first time, totally transparent, making it very simple to create a half-duplex link. The five-channel TDL2A effectively replaces a serial cable interface in a multitude of applications where trailing cables are impractical or undesirable, delivering a foolproof, low power, 100 m data link.
Unlike other solutions on the market that require the user to possess a considerable amount of radio expertise to successfully install, the company claims the TDL2A makes no such demands. Combining a sophisticated 433 MHz band five-channel transceiver with a dedicated data communication processor, the module deals with any 9600 baud asynchronous data stream issues without requiring any user intervention or interface, and provides all necessary buffering, packetisation, framing, coding, decoding and reconstitution. Further, the TDL2A does not require any additional software, and even eliminates the need for a transit-enable pin as it constantly monitors the channel for valid data. All the user has to do is add a 5 V power supply and aerial says Radiometrix.
Unlicensed operation is permitted throughout Europe under EN300-220. For multiple radio systems (polled networks) the TDL2A can be set to one of eight unique addresses. Additonally, as the TDL2A modules operate on one of five non-overlapping pre-set frequencies in the 433 MHz band, several modules can be in use simultaneously in the same area without interference.
Housed in an industry-standard 33 x 25 x 7 mm BiM2 footprint case, the TDL2A has a transmit power of only 10 mW. The units feature good RF specifications, including a receiver blocking performance of 84 dB. Receiver sensitivity is
-107 dBm (1%BER), adjacent channel rejection is 65dB at ±320 kHz and spurious emission is less than 65 dBm.
Applications are numerous and varied, but include machine to machine interfaces, industrial control and telemetry, handheld portable terminals, medical equipment and environmental monitoring and control systems.
