Wireless data modems

01/24/2007



Wireless data modems from Futaba Corp. are now available in module form and ready for integration into electronic products. Futaba Corp. offers three choices of its wireless technology, the FRH-SD07T, the FDL-01, and the FDP01T. This family of modules share similar operating characteristics in the 2.4 GHz ISM band under FCC Part 15.247. All three devices can support various network configurations, and include an asynchronous serial 3V CMOS level interface for ease of connection to an embedded host or an RS-232 type driver. The FRH-07T features high performance with an extremely low current consumption of & 35mA for transmitting/receiving operation, and & 70uA for‘sleep’ mode operation. The data rate is settable from 300 bps to 115.2 kbps. Single frequencies or groupings are selectable from an available 94. Automatic error detection and retransmission are included in the firmware. A diversity antenna feature helps overcome reception problems in areasprone to multi-path fading commonly encountered in manufacturing plants. The FDL-01 also features a higher data rate of 300 bps to 230.4 kbps. The FDP01T provides a smaller, lower cost solution. Lower cost is achieved by using FSK modulation in 80 frequencies and lower transmitting power.

Annual Salary Survey

After two years of economic concerns, manufacturing leaders once again have homed in on the single biggest issue facing their operations:

It's the workers—or more specifically, the lack of workers.

The 2017 Plant Engineering Salary Survey looks at not just what plant managers make, but what they think. As they look across their plants today, plant managers say they don’t have the operational depth to take on the new technologies and new challenges of global manufacturing.
