Abstract
The utility model provides a multi-serial port device with six serial ports, and belongs to the computer device filed. The multi-serial port device comprises a main board, a SIO chip, a DB26 interface and a patch cord; the main board, the SIO chip, the DB26 interface and the patch cord are connected in sequence, and the six serial ports are led out by the patch cord. Because of the adoption of a single chip supporting mode, the multi-serial port device has the advantages of cheap cost, no occupation of other interface resources and good stability.
Description
[technical field]
The utility model relates to a kind of many serial equipments, and particularly a kind of many serial equipments with six serial ports belong to the computer equipment field.
[background technology]
Nowadays, rapid development of computer technology, every field has been goed deep in the application of computer equipment.Systems such as postal service, bank have used many serial equipments in a large number, the terminal platform of such industry needs the many serial equipments of prolonged application, its demand for serial ports quantity is also continuing to increase, because the serial ports of common many serial equipments is not enough, and Interface design is very crowded, substantially, be difficult to satisfy the demands, therefore need the quantity of serial ports is expanded, usually it is expanded to 6 serial ports.
As shown in Figure 1, many serial equipments of the prior art need use 2 SIO (being system's input and output) chip just can realize the expansion of 6 serial ports, one of them SIO chip is drawn 4 serial ports, mouse interface, keyboard interface and parallel interfaces, and another SIO chip is drawn 2 serial ports.Or other interface by mainboard, carry out the expansion of serial ports as interfaces such as PCI, USB.There is the cost height in it, and takies other interface resource of mainboard, shortcomings such as poor stability.
[summary of the invention]
The technical problems to be solved in the utility model is to provide a kind of many serial equipments with six serial ports, and it uses the single-chip support pattern, and is with low cost, and does not take other interface resource, good stability.
The utility model is achieved in that a kind of many serial equipments with six serial ports, comprises a mainboard, system's I/O chip, a D type 26PIN interface and a patchcord; Described mainboard, system's I/O chip, DB26 interface and patchcord connect in turn, draw six serial ports by described patchcord again.
Wherein, this mainboard comprises a South Bridge chip, and described system I/O chip links to each other with this South Bridge chip.
Wherein, described system I/O chip is also drawn a mouse interface, a keyboard interface and a parallel interface.
The beneficial effects of the utility model: it adopts the single-chip support pattern, with system's I/O chip be connected with mainboard the back by a DB26 interface again through patchcord 6 serial ports of transferring out, on the one hand, need not to utilize two system's I/O chips, effectively reduce cost; Need not to take other interface resource of mainboard on the other hand; Moreover single chip solution has promoted mainboard stability and reliability, has effectively saved the space of rear port plate, creates favorable conditions for placing other interface.
[description of drawings]
In conjunction with the embodiments the utility model is further described with reference to the accompanying drawings.
Fig. 1 is existing configuration diagram with many serial equipments of six serial ports.
Fig. 2 is the configuration diagram that the utlity model has many serial equipments of six serial ports.
[embodiment]
See also shown in Figure 2ly, a kind of many serial equipments with six serial ports comprise a mainboard 1, one SIO (being system's input and output) chip 2, a DB26 (being D type 26PIN) interface 3 and a patchcord 4, and this mainboard 1 comprises a South Bridge chip 12.Described mainboard 1 links to each other with SIO chip 2 by this South Bridge chip 12; Described SIO chip 2, DB26 interface 3 and patchcord 4 connect in turn again, draw six serial ports 5 by described patchcord 4 at last, are respectively COM1, COM2......COM6.Wherein, described SIO chip 2 is also drawn a mouse interface 6, a keyboard interface 7 and a parallel interface 8.
For banking system graphic terminal platform, mainboard 1 model is ICH6, SIO chip 2 employing models are that the chip of SCH3116 carries out the design of 6 serial ports, described SCH3116 chip carry on the LPC of mainboard ICH6 (Low Pin Count promptly saves the interface of line number) bus, is expanded mouse interface, keyboard mouth and a parallel interface as LPT by the SCH3116 chip simultaneously.And described SCH3116 chip is drawn six serial ports by DB26 interface and patchcord again, is respectively COM1, COM2......COM6.
Because generally external unit only needs the transmission and the received signal of serial ports, though the serial ports 1 of SCH3116 chip can be drawn complete serial ports to serial ports 4, for saving the space, choose and used the port of DB26F to expand, only keep a full signal serial ports, other five serial ports are only drawn and are sent and received signal, and the DB26 port can be drawn 6 serial ports like this.The DB26 port has the good intensity that patches, and can fix by trip bolt, and reliability has bigger assurance.
In sum, the utility model adopts the single-chip support pattern, with system's I/O chip be connected with mainboard the back by a DB26 interface again through patchcord 6 serial ports of transferring out, other interface resource that need not to utilize two chips and take mainboard, effectively reduce cost, simultaneously also promoted mainboard stability and reliability, effectively saved the space of rear port plate, created favorable conditions for placing other interface.
