Ross Tech Usb Library Version 03.01.19

Older Ross-Tech RS-232 Serial interfaces can be set to power up as "dumb K-Line pass through" interfaces. This allowed those old Serial interfaces to be compatible with a wide variety of third-party applications which expect a "K-line pass-through" serial interface. However, our USB interfaces present additional challenges. Early in their development, we found a number of technical advantages to using a "direct" USB driver which bypasses the Windows Serial drivers entirely. Hence the USB drivers that ship with VCDS do not emulate a serial COM port and cannot be used with applications that expect to communicate via a serial port.
NOTE: The following applies to our legacy USB interfaces (HEX-USB, KII-USB and HEX-USB+CAN). It does NOT apply to our current HEX-V2 or HEX-NET interfaces. These new interfaces do not use a USB UART chip and cannot be be used for "dumb K-line pass-through"!
Now that the Environmental Protection Agency is recommending that every state use their biomonitoring protocol for measuring pollution, Virginia Tech entomologists are assisting the Virginia Water Control Board in implementing these new techniques.
"When kids are given a technological problem to solve by designing and building something, they become personally engaged in the problem," says Sanders. "They may also become more curious about the scientific or mathematical ideas behind the problem."
With over $400,000 from the National Science Foundation, the two are working with Virginia middle-school teachers to integrate hands-on activities in technology education courses with the math and science curricula.
Math, science, and technology education are currently taught as "separate little boxes," says LaPorte. He and Sanders want to put "glass walls" around those boxes so students can see the interrelationships among the subjects.
Student create their own solutions to technological problems. For example, students are asked to design and construct a model of a better transportation device for transporting toxic materials that is pneumatically or hydraulically controlled by syringes and plastic tubes. After students have built their devices, either individually or in teams, the teacher can challenge them to further apply math and science principles, Sanders says.

In an article published in the May 1997 issue of College and Research Libraries Merri Beth Lavagnino traced the history of the systems librarian and systems department in academic libraries. She identified four evolutionary stages, where Stage One was no automation and Stage Four was characterized by the effects of networking and distributed computing. Lavagnino ended her article by predicting the emergence of a fifth stage. However, she pointed out it was too early to describe that stage. This paper examines the growth of automation at two university libraries, with particular attention to the four stages described by Lavagnino. The authors then attempt to provide a more complete description of Stage Five. It seems to be an outgrowth of the distributed computing and networking components of Stage Four. New factors include a growth in digitized resources, integration of systems, and developments in client/server technology, especially as they relate to the World Wide Web. Finally, Stage Five libraries seem to have made changes in the organizational structure, reflecting a need for a technical person at the upper management level.
