詳細請參考wiki
https://en.wikipedia.org/wiki/XL ... l_usage_information

Prior to the introduction of this standard, the wiring of pins 2 and 3 varied. The pin 2 "hot" and pin 3 "cold" convention was typically used by European and Japanese equipment manufacturers, but American companies used pin 3 "hot" and pin 2 "cold". This caused problems when interconnecting equipment with unbalanced connections. The pin 3 "hot" convention is now obsolete but is still found on vintage equipment.[19] Pin 1 has always been ground and/or shield if the cable is shielded, and many connectors connect it internally to the connector shell or case.

小弟門外漢,如何可正確測量出極性就唔識啦,
平衡傳輸涉及正反相波形,應該要用示波器分辦吧。
我會覺得問廠/上網搵資料應該係比較正常做法。
2hot 3cold應該係比較普及接法。
又點解唔直接講出牌子型號?唔係更有幫助大家去諗咩?
