Description

M244534 V. Creation Instructions (1) [Scope of Creation] This creation is an external flash memory card reader with 1 3 94 interface specifications, especially a 1 3 9 4 connection cable to connect to a computer 1 3 9 4-port plug-in box, the plug-in interface can insert external flash memory cards (FLASH CARDS) and other external memory cards into the shell, for external flash memory read-write transfer function, which has a 1 3 9 4 size The computer with transmission characteristics can connect external memory cards to achieve 1 3 94 fast data transmission. [Background of creation] Due to the increasing diversification of computer peripherals and the various transmission specifications set by various vendors in the early stages of computer development, many plug-in connections between computer hosts and various peripheral devices have appeared. Connection specifications, the use is extremely confusing 'from the most basic and popular C0M1, COM2, PARALLEL / PRINTER port in the early days, to the current SCSI and other transmission connectors with multiple pin numbers' increase the user's external peripheral equipment to plug in the computer In particular, the few plug connectors with different transmission specifications have so far broken the tacit understanding of the standard specifications of different device plug connectors, often causing users to insert the wrong peripheral device connection bee, making the computer installation and use difficult to popularize the consumer. In addition, 'Various hardware peripherals need to be filled with driver software of the corresponding specifications under the operating system of the computer and carefully set conflicting addresses' in order for the computer to smoothly drive the connected peripherals. When the device is installed, the port of the peripheral device is incorrectly inserted. After the corresponding driver software is installed and set, the peripheral device cannot be operated. People often think that the address conflict is not resolved and the most basic connector is ignored. The problem of incorrect insertion makes it more difficult to eliminate errors on the computer installation.

Creative Instructions (2) Certificates were installed immediately, software and hardware equipment, and various peripheral settings were adjusted without worrying about misplug and plug and play.业 者 所 # Both can plug in a single type to further make it drive software specification capture. "The concept is popularized to the idea of operating a unified connection specification port, you can connect positive programs can be easily" so there is "Compaq", "DEC", "IM", "Int e1", "MiCr0Sft", etc., and USB (Universal Serial Bus) specifications developed by the USB organization Hope that with the usb interface

Consumers can replace the traditional interface with consumers that make PCs more rusty. They can also plug and play and use personal computers easily. However, the USB interface is only suitable for slow and medium speeds (1Mb it ~ 12Mbit) such as keyboards and mice. Etc., the peripheral equipment is used, so the storage system that needs high-speed transmission must use the high-efficiency serial bus (I EEE 1 3 9 4) formulated by the "American Institute of Electronic and Electrical Engineers (IEEE)" The effect of high-speed transmission, today's 1 3 94 transmission bandwidth is as high as 40 0Mb it is more efficient than USB, | $ 7, after thousands of years from outside the town, ㈣ personal computers and peripherals are very reasonable == faster and faster '1 3 9 4 specifications will gradually become popular, but the current 1 394 interface specification, which is an expansion device for external flash memory cards for computers,

Still, the people in the computer industry need to work hard to build a bridge using 1 394 standard equipment. Therefore, in view of the high-efficiency 1 3 9 4 specifications, there is still a lack of expansion equipment for setting up an external memory card for the computer. The creator is actively creating and researching, and after a arduous creative process, this creation finally came into being. [Overview of Creation]
