Does anyone know how to use this USB cable to split signal?


Recommended Posts

Hello.

 

Does anyone know how to use this USB cable to split between signal and power?

 

I guess that USB A male to USB B male is for purely signal transfer and the USB B female at the back is to feed 5v USB power?

 

If anyone used this type of USB cable before, please enlighten me. 

 

Thank you...

I think you got it the other way around.

 

Male A is used to supply power to male B via the power pins, and you get signal out from female B through another cable. I'm assuming power lines between male and female B had been cut so there is isolation.

Thank you. It is kinda making sense. 

 

I am trying to connect Topping D10 which takes both signal and power from desktop/laptop via USB and I am thinking to split the signal and power and feed the power from 5v linear power supply.

 

Have I understood correctly that USB A male is to be connected to Desktop since desktop does not take USB B type and signal travel from USB A to USB B Male.

USB B Male has signal and power pin separated so LPS is connected to the back of female USB B socket and the male USB B is now carries both signal and power and is to be connected to Topping D10 USB socket.

No I think you plug male B into the D10 and male A into your power source. Like a phone charger or similar.

 

You connect desktop to D10 via a typical male B to male A cable. Call this the printer cable. The printer cable will normally also carry power from desktop to D10, but not in this case because power lines between the female and male B (on the cable in the photo) are cut. In this photo cable, male A supply power to male B so your printer cable's power is unused.
