Toronto,Canada – GAO Embedded has released this universal programmer offering a 48 Pin ZiF socket with universal pin-driver. It automatically identifies the manufacture and type of EPROMs, TTL/CMOS logic ICs and dynamic or static random access memory devices; it also conducts device insertion and proof-pin-contact check. This module supports more than 10000 devices to meet various needs for device programming and IC testing. It provides optimum programming for each individual device.
GAO Embedded’s universal programmer, Model VP58B, features high programming speed, vector test capability, multi-array fuse map editor and auto-run mode; auto-run mode starts programming automatically upon detection of chip insertion. It supports 1.5V low voltage devices, as well manages 16-bit and 32-bit word split. With the USB port, it requires no external adapter. The universal programmer supports most compliers in JEDEC format including ABEL, CUPL, PALASM, TANGO PLD, or CAD PLD, PLD Designer and ISDATA.

ng>How to add more USB Ports to your PC or Laptop by using a USB Hub
More and more devices are now connected to PC via USB than ever before and given how simple USB technology is its no surprise. The fact that a USB connector on your PC can deliver power as well as transfer data (if needed) means that technology manufacturers are constantly looking at new ways to take advantage of the ease and simplicity that a USB connection offers. This proliferation of devices that plug into your USB ports is great but it does mean that pretty quickly you’ll find yourself without enough USB ports on your PC to support all the devices you want to connect to your PC via USB.
Fortunately it’s a problem that has a simple solution. A USB Hub (typically a 4 Port USB Hub or a 7 Port USB Hub) allows you to add more USB ports to any PC or Mac. The USB hub connects to your PC via a single USB cable but it then provides either 4 or 7 new USB ports for you to plug your devices into. So, a 4 Port USB Hub will give you 3 additional USB ports (remember you’ll use one to connect the hub to so a 4 port hub actually adds 3 additional USB ports) and a 7 Port USB Hub will give you 6 additional USB ports.
Because the USB ports on your PC will deliver power to the USB Hub the new USB ports the hub creates will have some power (without the need the a separate power supply) - Non powered or USB BUS powered hubs are ideal when you are looking to use the hub for devices likes USB Card readers, USB Memory Sticks, USB Bluetooth adapters, small USB gadgets etc but if you are looking to use the hub to plug in large “power hungry” devices like Printers, Scanners, Modems, Large external disk drives, etc then you would be advised to buy a USB hub that has its own additional power supply.
The vast majority of powered USB hubs can be used without the power but the benefit of the additional power supply is that if the hub can’t get enough power from the USB port its connected to then at least you can power the devices connected to it by plugging in the power supply unit.
At USBNow we carry a wide range of powered and non-powered USB hubs with prices starting from as little as £4.99. If you spend over £10 you can take advantage of our offer to buy a 4-port USB pocket hub for only 99p!!!

HDTV cables are conduits of HDTV transmissions. There are two kinds of HDTV connections: analog or digital. Various HDTV cables are used for these connections. They should be of good quality and well installed to guarantee a fully reliable system.
Analog HDTV cables
Analog HDTV signals are either RGB (usually RGBHV) or component video (Y/Pb/Pr).
Component connections are made using RCA connectors. These connectors transfer SDTV NSTC signals from external devices such as DVD or VHS to HDTV displays. Component cables are usually color coded: green for Y, blue for Pb and red for Pr. Audio cables are also color-coded: red for Right audio and white for Left audio.
Seventy-five (75) ohm video coaxial cables are suitable for these applications. These HDTV cables end with RCA plugs, BNCs or VGA monitor plugs.
HDTV analog signals are ten times stronger than NTSC. HDTV signals scale up to 35 MHz while NTSC reaches only up to 3.5 MHz. It is important that HDTV cables which connect devices together maintain a consistent impedance of 75 ohms. HDTV cables which do not meet proper specifications will cause ghosting or “ringing” of projected images because portions of the signal issues back and forth within the cable instead of being smoothly delivered to the screen.
Before purchasing analog HDTV cables, make sure that the device has been sweep-tested at least up to 105 MHz. Also, check that the impedance tolerance is 75 ohms within +/- 1.5 ohms.
Digital HDTV cables
Digital HDTV cables exist in SDI or Serial Digital Interface. However, this very strong cable is still commercially unavailable. In the market are the DVI (Digital Visual Interface) and HDMI (High-Definition Multimedia Interface ).
Bi-directional connection between computers and monitors is possible through dual-channel versions of DVI. These connections carry only video. Audio must be carried by other HDTV cables.
HDMI carries digital uncompressed audio between devices such as an STB and a display. Smaller connectors are used with HDMI. The HDMI HDTV cable allows for bi-directional interface also. HDMI uses a 19 pin connector for single link or a larger 29 pin connector for dual link.
Cables to interconnect DVI and HDMI devices are also available.
DVI and HDMI are characterized by very short cable lengths because they designed to house a copy-protection scheme. Digital HDTV cables use twisted-pair cable not coaxial cables which analog HDTV cables use. DVI and HDMI work without problems over short distances but some low-quality cables falter beyond ten feet.
Practically no digital HDTV cable works beyond fifty feet. Pre-formed DVI cables up to 10 ft. in length are available. Longer lengths require specialized materials and are expensive. Although digital interconnections produce highest video and audio quality, running over long distances is the limitation of digital HDTV cables.
Other cables
S-Video Cables. are used in some televisions to improve picture quality of NTSC signals. Audio must be interconnected separately using RCA cables. S-Video cables are available in any length.
F Cables are coaxial cables with F-connectors used to connect to antennas or satellite dishes to the TV cable system. Several possible cables are selected depending on the length needed. RG-59 is acceptable for short lengths but a low-loss cable is needed for roof-top antennas.
Mini DB 15 RGB Monitor Cables are used to connect PC to HDTV displays with analog RGB interfaces. These cables extend up to 5 meters. Special cables are needed beyond this length. Screw locks secure the connectors to warrant a firm connection.
Firewire/1394 is designed for digital video connections. Audio and video are carried together. The four pin version is the most common but six pin versions are also available for some devices. Prefabricated HDTV cables like these are up to 3 meters.
Dolby Digital audio in SPDIF format is frequently transmitted in optical form. Fiber link, an optical fiber cable which is also called “optical audio output cable”, may be employed to send these transmissions to the decoder in the audio system. Excessive bending or twisting of these cables must be avoided as not to break the fiber inside.
