Abstract:
1. A display device for indicating connection statuses of a communication channel provided between two systems, the communication channel having a plurality of PHY portions defining a plurality of communication links therein, the display device comprising: a detecting circuit coupled to the communication channel for detecting a plurality of link statuses of the communication links, the detecting circuit thereby monitoring a link status of each communication link one independent of the other, wherein the communication channel comprises a plurality of connection statuses including: a first connection status indicating an “ON” state for all the link statuses, a second connection status indicating an “OFF” state for all the link statuses, and a third connection status indicating an “ON” state for at least one of the link statuses and an “OFF” state for at least one other of the link statuses; an light emitting diode (LED) indicator controller coupled to the detecting circuit for determining the connection statuses of the communication channel according to independent variations of the link statuses monitored by the detecting circuit; an LED indicator coupled to the LED indicator controller for displaying a plurality of statuses according to the connection statuses from the LED indicator controller; and a timer coupled to the LED indicator controller for controlling blinking of the LED indicator, wherein the first connection status, the second connection status and the third connection status are represented by “ON”, “OFF” and the blinking of the LED indicator; the first connection status is represented by “ON” of the LED indicator, the second connection status is represented by “OFF” of the LED indicator, and the third connection status is represented by the blinking of the LED indicator.
