Middlesex, United KingdomThe TDi2 from Radiometrix is a RS232 interface board that combines a TDL2A 433-9 OEM multi-channel wireless modem module (operating at a half-duplex serial data rate of 9600bits/s ), an RS232 driver, a 9 way DB9F connector, helical SMA aerial and power connectors, and a local 5V voltage regulator.
A pair can be used as a serial RS232 cable-replacement in many 9600-baud half-duplex applications by hooking them up to a 6 to 15V power supply. In addition, it operates without the need for any additional interface circuitry. Status LEDs indicate reception of valid data packets and power on, and it can be enabled by DTE asserting DTR.
The synthesizer-based TDL2A module operates on five non-overlapping frequencies in the 433MHz European ISM band with the option to choose eight addressed point-to-point links. Its -107dBm sensitive receiver and full 10mW transmit output power combine to offer a typical range of more than 200m
Portable applications include remote data acquisition and industrial telemetry systems, and interfaces easily to handheld terminals, PDAs, laptop computers, and data loggers. It conforms to both EN 300 220-3 and EN 301 489-3 standards.
