Abstract
The utility model discloses a data extender which comprises a near-end unit and a far-end unit. The near-end unit and the far-end unit are connected through a network cable and are respectively provided with an input-output interface, a processor and a network cable interface.The input-output interfaces are connected with the network cable interfaces through the processors. The input-output interface of the near-end unit is connected with an input-output interface of a host computer. The network cable interface of the near-end unit is connected with the network cable interface of the far-end unit. The input-output interface of the far-end unit is connected with an order input unit. By the adoption of the data extender, the order input unit such as a keyboard and a mouse can be connected in a position far away from the host computer. Thus, the host computer can be managed conveniently, and radiation is small. Moreover, an operator can not influence the operation of the host computer easily, and the host computer is good in operation stability.
Description
Technical field
The utility model relates to field of computer technology, relates in particular to a kind of data extender.
Background technology
Main frame of the prior art is generally all indoor, and the instruction input block, such as keyboard, mouse etc. also all is inserted on main frame, by instruction input block main control system.But because the instruction input block is positioned at the place not far with main frame, management host inconvenience, radiation is larger, and operating personnel very easily affect the operation of main frame, and the main frame operation stability is bad.
The utility model content
The utility model provides a kind of data extender, and the instruction input block can be connected with main frame by the data extender, realizes the Long-distance Control to main frame, and management host is convenient like this, and radiation is very little, and the main frame good operation stability.
The technical solution of the utility model is:
A kind of data extender, it comprises near-end unit and the far-end unit connected by netting twine, and near-end unit and far-end unit all include IO interface, processor and cable interface, and IO interface is connected with cable interface by processor;
The IO interface of near-end unit is connected with the IO interface of main frame, and the cable interface of near-end unit is connected with the cable interface of far-end unit; The IO interface and instruction input block of far-end unit connects.
Use data extender of the present utility model, the instruction input block, such as keyboard, mouse etc. can be received the place distant with main frame, realize the Long-distance Control to main frame, can facilitate management host like this, and radiation is very little; And operating personnel are not easy to affect the operation of main frame, the main frame operation stability is relatively good.
The accompanying drawing explanation
Fig. 1 is data extender of the present utility model structure principle chart in one embodiment.
Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the utility model is done to a detailed elaboration.
As Fig. 1, data extender of the present utility model, comprise the near-end unit and the far-end unit that by netting twine, connect, near-end unit and far-end unit all include IO interface, processor and cable interface, and IO interface is connected with cable interface by processor;
The IO interface of near-end unit is connected with the IO interface of main frame, and the cable interface of near-end unit is connected with the cable interface of far-end unit; The IO interface and instruction input block of far-end unit connects.
The operator is by instruction input block input command information, this input command information arrives the processor of near-end unit by network cable transmission after the processor of far-end unit is processed, the processor of this near-end unit will be inputted the signal that instruction transformation is main frame identification, thereby reach the Long-distance Control to main frame.By data extender of the present utility model, the instruction input block, such as keyboard, mouse etc. can be received the place distant with main frame, can facilitate management host like this, and radiation is very little; And operating personnel are not easy to affect the operation of main frame, the main frame operation stability is relatively good.
For the closing or opening of better main control system, the power switch port of main frame is connected with the processor of near-end unit.Can control by long-range power switch to main frame like this, easy to operate.
Described instruction input block can comprise the similarly input block such as keyboard or mouse.
Above-described the utility model embodiment, do not form the restriction to the utility model protection domain.Any modification of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in claim protection domain of the present utility model.
