在本發明一實施例中，當切換電路40判斷出從第三介面43所接收到的訊號S1中包含預定字串時，切換電路40會將第一介面41耦接於第三介面43，並切斷第一介面41與第二介面42之間的電性連接。如此一來，RJ45連接器20的 第二組腳位G2的多個腳位A4、A5、A7和A8即可分別耦接於第三介面43的多個腳位31至34。在此情況下，RJ45連接器20可透過第二組腳位G2及第三介面43與監控裝置90進行通訊，且RJ45連接器20還可透過第一組腳位G1與網路卡30的第三組腳位G3進行通訊。因此，監控裝置90即可透過第三介面43和第一介面41，監控電子設備70的狀態，或更新電子設備70之晶片74的韌體。同時，電子設備70可透過第一組腳位G1和第三組腳位G3連接於網路80。此時，電子設備70與網路80之間的傳輸率為第一傳輸率，而第一傳輸率可以是每秒100兆位元(即：100Mbps)，但本發明不以此為限。上述訊號S1中所包含的預定字串的長度和其內容主要是由監控裝置90決定，不同的監控裝置90其訊號S1所包含的預定字串可以互不相同，而切換電路40可設計成得以判斷不同監控裝置90所產生的不同的預定字串，並依據訊號S1中是否包含有預定字串而將第一介面41耦接於第二介面42或第三介面43。另一方面，當切換電路40並未判斷出從第三介面43所接收到的訊號S1中包含預定字串時(如：第三介面43沒有接收到訊號S1，或所接收到的訊號S1中並未包含預定字串時)，切換電路40會將第一介面41耦接於第二介面42，並切斷第一介面41與第三介面43之間的電性連接。如此一來，RJ45連接器20的第二組腳位G2的多個腳位A4、A5、A7和A8即可分別耦接於第二介面42的多個腳位21至24。在此情況下，RJ45連接器20的第二組腳位G2的多個腳位A4、A5、A7和A8分別藉由腳位11至14及21至24，而耦接於網路卡30的第四組腳位的多個腳位B4、B5、B7和B8。此時，電子設備70與網路80之間的傳輸率為第二傳輸率，而第二傳輸率會高於上述的第一傳輸率。舉例來說，第一傳輸率可以是每秒100兆位元(即：100Mbps)，第二傳輸率可為每秒1000兆位元(即：1000Mbps)，但本發明不以此為限。 In an embodiment of the present invention, when the switching circuit 40 determines that the signal S1 received from the third interface 43 contains a predetermined string, the switching circuit 40 couples the first interface 41 to the third interface 43, and The electrical connection between the first interface 41 and the second interface 42 is cut off. As a result, the RJ45 connector 20 The plurality of pins A4 , A5 , A7 and A8 of the second group of pins G2 can be respectively coupled to the plurality of pins 31 to 34 of the third interface 43 . In this case, the RJ45 connector 20 can communicate with the monitoring device 90 through the second set of pins G2 and the third interface 43 , and the RJ45 connector 20 can also communicate with the first set of pins G1 and the third interface of the network card 30 through the first set of pins G1 Three groups of pins G3 communicate. Therefore, the monitoring device 90 can monitor the state of the electronic device 70 or update the firmware of the chip 74 of the electronic device 70 through the third interface 43 and the first interface 41 . Meanwhile, the electronic device 70 can be connected to the network 80 through the first group of pins G1 and the third group of pins G3. At this time, the transmission rate between the electronic device 70 and the network 80 is the first transmission rate, and the first transmission rate may be 100 megabits per second (ie, 100 Mbps), but the invention is not limited thereto. The length and content of the predetermined string included in the signal S1 are mainly determined by the monitoring device 90. The predetermined string included in the signal S1 of different monitoring devices 90 may be different from each other, and the switching circuit 40 can be designed to Different predetermined strings generated by different monitoring devices 90 are determined, and the first interface 41 is coupled to the second interface 42 or the third interface 43 according to whether the signal S1 contains the predetermined strings. On the other hand, when the switching circuit 40 does not determine that the signal S1 received from the third interface 43 contains a predetermined string (eg, the third interface 43 does not receive the signal S1, or the received signal S1 When the predetermined character string is not included), the switching circuit 40 couples the first interface 41 to the second interface 42 and cuts off the electrical connection between the first interface 41 and the third interface 43 . In this way, the plurality of pins A4 , A5 , A7 and A8 of the second group of pins G2 of the RJ45 connector 20 can be respectively coupled to the plurality of pins 21 to 24 of the second interface 42 . In this case, the plurality of pins A4, A5, A7 and A8 of the second group of pins G2 of the RJ45 connector 20 are coupled to the network card 30 through pins 11 to 14 and 21 to 24, respectively. A plurality of pins B4, B5, B7 and B8 of the fourth group of pins. At this time, the transmission rate between the electronic device 70 and the network 80 is the second transmission rate, and the second transmission rate is higher than the above-mentioned first transmission rate. For example, the first transmission rate may be 100 megabits per second (ie, 100 Mbps), and the second transmission rate may be 1000 megabits per second (ie, 1000 Mbps), but the invention is not limited thereto.

在本發明另一實施例中，當切換電路40並未判斷出從第三介面43所 接收到的訊號S1中包含預定字串時(如：第三介面43沒有接收到訊號S1，或所接收到的訊號S1中並未包含預定字串時)，切換電路40會將第一介面41耦接於第三介面43，並切斷第一介面41與第二介面42之間的電性連接。如此一來，RJ45連接器20的第二組腳位G2的多個腳位A4、A5、A7和A8即可分別耦接於第三介面43的多個腳位31至34。在此情況下，RJ45連接器20可透過第二組腳位G2及第三介面43與監控裝置90進行通訊，且RJ45連接器20還可透過第一組腳位G1與網路卡30的第三組腳位G3進行通訊。因此，監控裝置90即可透過第三介面43和第一介面41，監控電子設備70的狀態，或更新電子設備70之晶片74的韌體。同時，電子設備70可透過第一組腳位G1和第三組腳位G3連接於網路80。此時，電子設備70與網路80之間的傳輸率為第一傳輸率。另一方面，當切換電路40判斷出從第三介面43所接收到的訊號S1中包含預定字串時，切換電路40會將第一介面41耦接於第二介面42，並切斷第一介面41與第三介面43之間的電性連接。如此一來，RJ45連接器20的第二組腳位G2的多個腳位A4、A5、A7和A8即可分別耦接於第二介面42的多個腳位21至24。在此情況下，RJ45連接器20的第二組腳位G2的多個腳位A4、A5、A7和A8分別藉由腳位11至14及21至24，而耦接於網路卡30的第四組腳位的多個腳位B4、B5、B7和B8。此時，電子設備70與網路80之間的傳輸率為第二傳輸率，而第二傳輸率會高於上述的第一傳輸率。 In another embodiment of the present invention, when the switching circuit 40 does not determine that the third interface 43 When the received signal S1 contains a predetermined string (eg, the third interface 43 does not receive the signal S1, or the received signal S1 does not contain the predetermined string), the switching circuit 40 switches the first interface 41 It is coupled to the third interface 43 and cuts off the electrical connection between the first interface 41 and the second interface 42 . In this way, the plurality of pins A4 , A5 , A7 and A8 of the second group of pins G2 of the RJ45 connector 20 can be respectively coupled to the plurality of pins 31 to 34 of the third interface 43 . In this case, the RJ45 connector 20 can communicate with the monitoring device 90 through the second set of pins G2 and the third interface 43 , and the RJ45 connector 20 can also communicate with the first set of pins G1 and the third interface of the network card 30 through the first set of pins G1 Three groups of pins G3 communicate. Therefore, the monitoring device 90 can monitor the state of the electronic device 70 or update the firmware of the chip 74 of the electronic device 70 through the third interface 43 and the first interface 41 . Meanwhile, the electronic device 70 can be connected to the network 80 through the first group of pins G1 and the third group of pins G3. At this time, the transmission rate between the electronic device 70 and the network 80 is the first transmission rate. On the other hand, when the switching circuit 40 determines that the signal S1 received from the third interface 43 contains a predetermined string, the switching circuit 40 couples the first interface 41 to the second interface 42 and cuts off the first Electrical connection between the interface 41 and the third interface 43 . In this way, the plurality of pins A4 , A5 , A7 and A8 of the second group of pins G2 of the RJ45 connector 20 can be respectively coupled to the plurality of pins 21 to 24 of the second interface 42 . In this case, the plurality of pins A4, A5, A7 and A8 of the second group of pins G2 of the RJ45 connector 20 are coupled to the network card 30 through pins 11 to 14 and 21 to 24, respectively. A plurality of pins B4, B5, B7 and B8 of the fourth group of pins. At this time, the transmission rate between the electronic device 70 and the network 80 is the second transmission rate, and the second transmission rate is higher than the above-mentioned first transmission rate.

由於網路介面10是藉由RJ45連接器20耦接於電子設備70的RJ45介面72，而RJ45介面72是電子設備70在出廠後仍會使用的到介面。故藉由本發明上述實施例的說明，監控裝置90通過網路介面10即可連接於電子設備70的RJ45介面72，以對電子設備70進行監控及韌體更新。同時，電子設備70仍可透過RJ45介面72和網路介面10連接於網路80。因此，電子設備70不須另外再設置其他介面，即可透過其原有的RJ45介面72連接於監控裝置90。因此，不但可節省電子 設備70的配置空間，相關人員也可透過網路介面10將監控裝置90連接於電子設備70以對電子設備進行監控及韌體更新，同時還保留了電子設備70連接至網路80的功能。 Since the network interface 10 is coupled to the RJ45 interface 72 of the electronic device 70 through the RJ45 connector 20 , the RJ45 interface 72 is still used by the electronic device 70 after it leaves the factory.
