Inc.'s SeaLINK+485-DB9 is a new single-port USB to RS-485 serial adapter
with a ruggedized, overmolded enclosure. The SeaLINK+485-DB9 offers fast serial
communication for tough environments, including factory floor, mobile and
The serial port appears as a standard COM port to the
host computer for setup and compatibility with legacy software. The
SeaLINK+485-DB9 has a programmable baud rate and data formats with 128 byte
transmit and 384 byte receive buffers. Each adapter includes a removable
terminal block adapter that simplifies field wiring. Thumbscrews on the TB34
secure the terminal block adapter to the serial port and prevent accidental
SeaLINK+485-DB9 is compatible with standard PC baud
rates and supports high-speed communication to 921.6K bps. The adapter is
powered by the USB port and status LEDs molded into the enclosure indicate
serial data activity and connection to the host.
SeaLINK USB serial adapters ship with Sealevel
Systems SeaCOM suite of Windows drivers and diagnostic utilities. WinSSD, a
full-featured application providing testing and diagnostic capabilities, is
also included. Use WinSSD for Bit Error Rate Testing (BERT), throughput
monitoring and transmitting test pattern messages.
To meet the demands of working in harsh industrial
environments, the SeaLINK+485-DB9 operates over an extended temperature range
of -40 - +85C. The attached 44 inch cable is fully shielded to protect the
adapter from RF and EMI interference, which are common in mobile and industrial
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
Airbus Defence and Space has 3D printed titanium brackets for communications satellites. The redesigned, one-piece 3D-printed brackets have better thermal resistance than conventionally manufactured parts, can be produced faster, cost 20% less, and save about 1 kg of weight per satellite.
A group of researchers at the Seoul National University have discovered a way to take material from cigarette butts and turn it into a carbon-based material that’s ideal for storing energy and creating a powerful supercapacitor.
