Phoenix Contact has added a basic
version of the Trusted Wireless Ethernet (TWE) radio. The TWE-Basic
(RAD-ISM-900-EN-BD/B) transmits Ethernet data from remote locations, even in
high interference environments.
The "basic" nature of the product
indicates the removal of the standard RS-232 and RS-485/422 ports. The
TWE-Basic is a "slave-only" device, so it must be used in conjunction with a
standard TWE or TWE-BUS radio acting as the master. Like the other Trusted
Wireless radios, the basic version features the MOTR-9 radio platform, a 1W,
frequency-hopping spread spectrum (FHSS) transceiver.† It operates in the
license-free 902-928 MHz ISM band. The MOTR-9 radio lets the user configure
over-the-air data rates up to 500 kbps. Adjustable packet sizes maximize data
speed and minimize latency.†The radio also incorporates selectable
128/192/256-bit AES encryption to prevent unwanted intrusion and keep data
The TWE family also includes the
RAD-ISM-900-EN-BD and the RAD-ISM-900-EN-BD-BUS. Both of these modules are
freely configurable as a master, slave or repeater and include RS-232/422/485
ports for integrating serial devices into IP-based networks. The bus version
also features an integrated expansion bus for connecting analog, digital and
pulse I/O modules that are addressable via Modbus.
Any network PC with a web browser can
configure the devices via embedded software. The entire family is listed for
use in Class I, Division 2 hazardous locations.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicleís parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but thatís just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
