1. Field of the Invention
The present invention relates generally to a community of peripheral apparatus for computers output/input, and more particularly, it is utilized to integrate a plurality of computers to share the community of keyboard, mouse and monitor, the firmware of the present invention can be upgraded using the existing PS2 ports and current PS2 protocols.
2. Description of the Prior Art
A peripheral community apparatus for computers output/input, such as Central Processing Unit (CPU) and KVM SWITCH, is utilized to integrate a plurality of computers to share the community keyboard, mouse, monitor and so on. In view of the fact that keyboards, mousse and monitors are fast renewing, and that protocols are frequently modifying, the peripheral community apparatus for computers output/input is fast eliminated through competition and its firmware must catch up with new computers. At present, peripheral community apparatuses for computer output/input with the upgrading function(Flash Rom Type) need extra output/input ports, such as RJ-45 -DB-9 -DB-25 port, and signal lines to connect to computers, then by the RS-232/I2C protocol the upgrading firmware programs are burned into the Flash ROM of the current peripheral community apparatus for computers output/input. Illustrated in
Furthermore, the current peripheral community apparatus for two computers output/input 10 comprises a community port 11, a first community port 12, a second community port 13, and a third community port 14; wherein the community port 11 is combined with a monitor 50, a keyboard 60, a mouse 70 by the community line connector 41; the first community port 12 is combined with the keyboard/mouse/monitor port 22 of the first computer 20 by the first community line connector 42; the second community port 13 is combined with the keyboard/mouse/monitor port 31 of the second computer 30 by the second community line connector 43. When the firmware of the current peripheral community apparatus 10 for two computers output/input is upgraded, at first the third community port 14 of the peripheral apparatus 10 for two computers output/input is combined with the first computer 20 or the second computer 30 by the third community line connector 44; in the case with the first computer 20; users store the upgrading firmware programs inside the first computer 20, then operate the keyboard 60 and the mouse 70 following the instructions on the monitor 50 to transmit the upgrading firmware programs, through the community line connector 44, from Serial port of the first computer 20 to the community port 11 and into the Flash Rom of the current peripheral community apparatus 10 for two computers output/input to complete the burning work. Whereby, the current peripheral community apparatus 10 for two computers output/input can keep working right with the new computers and the new peripheral apparatus.
The present invention provides a peripheral community apparatus for computers output/input which needs not extra connection ports and signal lines, but the existing PS2 ports on the current computers in firmware upgrading process.
As described above, the present invention makes use of the existing PS2 ports on both the peripheral apparatus for computer output/input and computers for keyboard/mouse use to upgrade the firmware of the peripheral apparatus for computer output/input. The upgrading firmware program is at first stored in computer, then transmitted into the Flash Rom of the peripheral apparatus for computer output/input through the PS2 line connector to complete the burning work. Using the existing PS2 ports spares extra connection arrangement and complicated operation steps in upgrading process.
The foregoing aspects and many of the attendant advantages of the present invention will become more readily appreciated as the same becomes better understood by reference to the following detailed description, when taken in conjunction with the accompanying drawings, wherein:
FIG.2 shows a framework illustrating how the peripheral community apparatus for two computers output/input is combined with the computers in accordance with one of the preferred embodiment.
What is probed into in the invention is a method needing no extra the connect ports and signal lines, but the existing PS2 ports when upgrading the firmware programs. Detailed steps in production, structure and elements will be provided in the following description in order to make the invention thoroughly understood. Obviously, the application of the invention is not confined to specific details familiar to those who are skilled in electromagnetic inductive system. On the other hand, the common elements and procedures that are known to everyone are not described in the details to avoid unnecessary limits of the invention. Some preferred embodiments of the present invention are described in greater detail in the following. However, it should be recognized that the present invention can be practiced in a wide range of other embodiments besides those explicitly described, that is, this invention can also be applied extensively to other embodiments, and the scope of the present invention is expressly not limited except as specified in the accompanying claims.
As illustrated in
Although a specific embodiment has been illustrated and described, it will be obvious to those skilled in the art that various modifications may be made without departing from what intends to be limited solely by the appended claims. Obviously, many modifications and variations of the present invention are possible in light of the above teachings. It is therefore to be understood that within the scope of the appended claims, the present invention may be practiced otherwise than as specifically described herein.
