Question :
hi
i’m using a cable tester that looks like this: http://hongmei.en.alibaba.com/product/200168769/51179510/Cable_Tester/Cable_Tester_468.html
upon troubleshooting a straight cat5 utp cable using the said device, all LEDs (1-8) light up except LED 2 (TX-) didn’t.
can someone enlighten me? is this a bad cable? open circuit perhaps?
Answer :
DTE are using pin 1, 2, 3 and 6, it will be used for TX+, TX-, RX+ and RX- respectively.
So, if LED on 2 is not light on, it would be defect one.
