I need converts a card reader/keyboard with RJ11 plug to USB plug, using pinout equivalence Regards
Carlos
There is no equivalence. USB has four pins, data, data ground, 5V power and power ground. You need the tech specs to see which pins are which on the RJ11. RJ11 is usually used on telephones with two twisted pairs carnying data. What is an RJ11 doing on a keyboard/card reader I have no idea. Stuart
