Description

Burning adapter board

Technical field

The present invention is a kind of burning adapter board, especially refer to a kind of when the storer on the motherboard is carried out burning program, can utilize this card extender to connect this motherboard and a CD writers, and by the reset indication and the burning signal level of this card extender, this motherboard is started shooting again and detect this burning signal level, and enter the burning state, therefore, this CD writers can be carried out burning program to this storer.

Background technology

Generally to electronic installation (as: computing machine, servies etc.) storer (as: but electronic type clear program ROM (read-only memory) (EEPROM)) on the motherboard (Mother board) carries out the mode of burning program, see also shown in Figure 1, be to be provided with an interface circuit 12 (as: RS-232 interface circuit) in this motherboard 11, one jumper 13 (Jumper) and a connectivity port 14, wherein, this interface circuit 12 respectively with this connectivity port 14, be electrically connected connects a storer 15 on this jumper 13 and this motherboard 11 (as: but electronic type clear program ROM (read-only memory) (EEPROM)), and this connectivity port 14 is electrically connected by a data line 16 and a CD writers (as: personal computer) (not shown) and connects.

Please consult shown in Figure 1 again, when the storer 15 to this motherboard 11 carries out burning program, earlier 131 transposings of the joint on this jumper 13 extremely can be produced on the position of burning signal level, again this motherboard 11 is started shooting again, after making this motherboard 11 start shooting again, can detect the burning signal level on this jumper 13, and enter the burning state, and then this burning function is carried out burning program to this storer 15.

Yet the mode of this existing burning program must install the burning built-up circuit that comprises interface circuit 12, jumper 13, connectivity port 14 additional on each motherboard 11, cause increasing manufacturing cost, and take the usage space of these motherboards 11; And when carrying out burning at every turn, all to set the joint 131 on this jumper 13, and these motherboards 11 are started shooting again, very inconvenience, especially these motherboards 11 are after dispatching from the factory, if forget the joint on this jumper 13 131 changed to original position, then will cause these motherboards 11 to maintain the burning state, and can't normal boot-strap.

Because the mode of aforementioned existing burning program, must on each motherboard, install the burning built-up circuit that comprises interface circuit, jumper, connectivity port additional, and when carrying out burning at every turn, all to set the joint on this jumper, reach the shortcomings such as inconvenience that these motherboards are started shooting again, inventor's development and Design goes out a kind of burning adapter board of the present invention.

Summary of the invention

A purpose of the present invention provides a kind of burning adapter board, and order makes CD writers carry out burning program to the storer on the motherboard by the reset indication and the burning signal level of this card extender.

According to above-mentioned purpose, this card extender is provided with one for the connectivity port that connects CD writers, one interface circuit (as: RS-232 interface circuit), one jumper (Jumper), one resets (Reset) commander sender and for another connectivity port that connects motherboard (Mother board), wherein, this interface circuit respectively with this connectivity port, this jumper, this reset indication transmitter and this another connectivity port are electrically connected, by changing the plug-in position of the joint on this jumper, and produce different signal level, and this connectivity port and this CD writers are electrically connected, and this another connectivity port then is electrically connected with this motherboard.

When to the storer on this motherboard (as: but electronic type clear program ROM (read-only memory) (EEPROM)) when carrying out burning program, can press the button on this reset indication transmitter, make this reset indication transmitter send this motherboard of reset indication, simultaneously, and with the joint on this jumper transposing to producing on the position of burning signal level, make this motherboard start shooting again and detect burning signal level on this jumper, and enter the burning state, so, this CD writers can be carried out burning program to this storer, reach when avoiding prior art to carry out burning program, must on this motherboard, install the burning built-up circuit additional, and set the inconvenience that jumper and system start shooting again.

Another object of the present invention, a kind of burning adapter board is provided, when order extremely can produce on the position of burning signal level when the joint of transposing on this jumper, the signal level of this jumper will by former positive 12 volts (+12V) convert 3.3 volts (V) (burning signal level) to, after this motherboard is started shooting again, can detect the burning signal level on this jumper, and enter the burning state.

Embodiment

The present invention is a kind of burning adapter board, see also Fig. 2, shown in Figure 3, this card extender 21 is provided with one for the connectivity port 22 that connects CD writers, one interface circuit 23 (as: No. 232 proposed standard interface (RS432 interface)), one jumper 24 (Jumper), one resets (Reset) commander sender 25 and for another connectivity port 26 that connects motherboard 31 (Mother board), wherein, this interface circuit 23 respectively with this connectivity port 22, this jumper 24, this reset indication transmitter 25 and this another connectivity port 26 are electrically connected and connect, this jumper 24 is provided with a set of joints 24, order can be by the plug-in position of the joint 24 on this jumper 24 of transposing, and produce different signal level, and this connectivity port 22 is electrically connected by a data line (not shown) and a CD writers (as: personal computer) (not shown), and 26 of this another connectivity ports are electrically connected with this motherboard 31 by another data line 261 and connect.

By forming of above-mentioned member, see also Fig. 2 again, shown in Figure 3, when to the storer 33 on this main frame 31 (as: but electronic type clear program ROM (read-only memory) (EEPROM)) when carrying out burning program, can press the button 251 on this reset indication transmitter 25, make this reset indication transmitter 25 send this motherboard 31 of reset indication, simultaneously, and with the joint on this jumper 24 241 transposing to producing on the position of burning signal level (as: 3.3 volts (V)), make this motherboard 31 start shooting again, and in detecting burning signal level (as: low (LOW) current potential) on this jumper 24 after the start again, and enter the burning state, so, this CD writers can be carried out burning program to this storer 33.

See also Fig. 2, shown in Figure 3 again, after finishing burning program, only need another data line 261 on this another connectivity port 26 is separated with this motherboard 31, can make this motherboard 31 return back to previous status, and not influenced by the burning signal level on this jumper 24.

See also Fig. 2, shown in Figure 3 again, this connectivity port 22 can be one No. 232 proposed standard connectivity port (RS-232 connectivity port), makes this connectivity port 22 be electrically connected by this data line and this CD writers and connects.
