Embodiment
Below in conjunction with drawings and the specific embodiments the utility model is further described in more detail.
In order to make equipment have better generality, adopt the Ethernet electrical interface that meets the IEEE802.3 standard to use the RJ45 connector in the utility model device.In a RJ45 connector, having four pairs of pins can utilize, but when providing Ethernet interface by the RJ45 connector in the prior art, has only used two pairs of pins to receive and send signal, and all the other two pairs of pins are idle no.The utility model scheme also uses two pairs of pins of free time, in a RJ45 connector, can provide two-way Ethernet electrical interface like this.
The structure of the preferable embodiment of the utility model Ethernet interface device is referring to shown in Figure 3.This Ethernet interface device comprises: at least one RJ45 interface 301, and more than one indicator light 302.RJ45 interface 301 can adopt the RJ45 interface of common RJ45 connector, and the 1st～8 pin of this RJ45 interface 301 is connected with transformer 201 on the Line Processing Unit 101.In these eight pins, 1st, 2,3,6 pins are one group, 4,5,7,8 pins are one group and connect one road Ethernet data line respectively, two-way 10/100Base-Tx Ethernet electrical interface so can be provided, wherein first group 1,2 and second group 4,5 pins are used for the reception of signal, rectify level signal Rx+ with the reception of transformer 201 respectively and link to each other with receiving terminal negative signal Rx-; First group 3,6 pins and second group 7,8 pins are used for the transmission of signal, rectify level signal Tx+ with the transmission of transformer 201 respectively and link to each other with transmitting terminal negative signal Tx-; Be two indicator lights 302 of each RJ45 interface 301 configuration in the present embodiment, be respectively applied for the state of indication two-way Ethernet electrical interface.The indicator light 302 anodal 3.3V power supplys that connect provide drive current, and negative pole is connected with PHY 202 by 330 Ω protective resistances 303 of series connection, and PHY 202 is according to the switch and the flicker of the Link/ACT index signal control indicator light 302 of Ethernet electrical interface state output.The Link and the ACT indicator light 302 that provide on the existing common RJ45 connector preferably can be provided, these two indicator lights 302 are reset: the solid colour that makes two indicator lights 302, green such as all adopting, and stipulate the Link and the act state of each indicator light 302 indications one road Ethernet interface, for example can stipulate indicator light 302 Chang Liang according to convention, the expression physical layer link is in good condition, normally transceive data; Indicator light 302 is with the certain frequency flicker, and expression has the data transmit-receive activity, and the ports physical state is normal simultaneously.So make and be used for indicating respectively the physical layer link state of same RJ45 interface 301 and the Link and the ACT indicator light 302 of data transmit-receive state originally, become two Link/ACT indicator lights 302, indicate the state of two-way Ethernet electrical interface in the same RJ45 interface 301 respectively, indicator light 302 shown amount of information did not reduce when the quantity of indicator light 302 had to increase.
