June 10, 2004... VALLEY VIEW, OHIO ? GELcore, LLC, an industry leader in developing innovative LED systems and advanced LED technologies for general illumination products, rounds out its GE Tetra? LED lighting system with the addition of a much-sought -after color: white. Created for major market segments such as retail, restaurant and hospitality, the GE Tetra LED lighting system operates as a light engine in channel letter, reverse halo, box and cloud signage, as well as cove and accent lighting applications .
Produced using a proprietary GE phosphor, the new GE Tetra white joins eight other colors already offered: red, red-orange, lemon yellow, goldenrod, blue, green, sky blue and aqua marine. An easy-to-install, easy-to -maintain alternative to neon lighting, the GE Tetra LED lighting system saves as much as 80 percent in energy costs over neon.
Our GE Tetra white LED system is the first white LED lighting system for signage applications to pass GELcores stringent reliability tests and carry the GE name, says Joe Melchiors, GELcore product manager. Now sign companies have a broad spectrum of colors to choose from, including White, in a system that installs quickly and easily. GE Tetra white is a win-win-win for distributors, OEMs and end-users.
The GE Tetra LED lighting system uses high-brightness LED modules connected to flexible, heavy-duty, 14-gauge wire thats packaged in reel form so it can be cut to any length. The low-voltage GE Tetra is a protected system that is </ br> <br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br><br>
The GE Tetra LED lighting system is virtually maintenance free: there are no burned out or broken bulbs or tubes to replace, no failed transformers to switch and nuisance tripping becomes a distant memory. Benefits include a longer rated life (up to 100,000 hours), The system is UL recognized and classified in the US; CSA approved in Canada; CE approved in Europe; and C-Tick approved in Australia. It holds an IP44 rating for water and dust intrusion. GE Tetra LED lighting systems are warranted for up to five years.

Small computer system interface (SCSI) is an independent processor standard for system level interfaces between computers and intelligent devices (hard disks, floppy drives, optical drives, printers, scanners, etc.). SCSI is an intelligent universal interface standard.
The last SCSI device in the SCSI chain uses a terminator, and the intermediate device does not need a terminator. Once the terminator is used by the intermediate device, the SCSI card cannot find the future SCSI device. If the last device does not use a terminator, SCSI will not work properly. Terminator is composed of resistors, located at the end of the SCSI bus, to reduce the mutual influence of the signal, maintain the constant voltage on the SCSI chain.
Most of the SCSI devices have built-in terminators and use a jumper to control on / off. The SCSI device is highly intelligent and can automatically control the terminator on / off. For example, if a hard disk is connected to a CD-ROM, the CD-ROM can work normally regardless of whether the terminator of the hard disk is on or off. However, when two hard disks are connected, the situation becomes more complicated. Before two Seagate hard disks are connected, one hard disk terminator must be off. Before a Seagate hard disk is connected to a quantum hard disk, a hard disk terminator can work normally regardless of whether it is on or off.
