Abstract:
A LAN link tester, comprisinga housing; an input connector for coupling to a LAN port, the input connector configured to couple to a network transmit pair line of the LAN port and a node transmit pair line of the LAN port; detection means for detecting link signals coupled to either the network transmit pair line or the node transmit pair line; line selection means for selectively and automatically coupling the detection means either to the network transmit pair line or to the node transmit pair line; circuit means for causing the line selection means to couple the network transmit pair line of the LAN port to the detection means, and if no link signal is detected, to automatically couple the node transmit pair line of the LAN port to the detection means, and responsive to a detected link signal determining available operational modes or a fault condition; and display means on the housing for displaying an indicia indicative of the operational modes or the fault conditions.
