Sending power for DS90UB927Q

Hello Atsushi,

Only differential (STP) interconnect is supported on the 927. Typically in an STP cable, there are 2 pairs of wires. One pair sends the data stream (DOUT +/-) and the other pair is typically unused (or GND'ed).

Power can either be sent over the same pair used for data or sent over the unused twin pair. Typically, it is common for customers to send power over the unused twin pair; one line is used for the DC voltage (i.e. 12V) and the other line is used as GND within the pair.

Dear Sean-san,

Thank you for your reply.

I understand we can send power with twist pair wire.

But I don't understand how to realize it very well.

Are there any materials for sending power with twist pair wire?

Best regards,

Atsushi Yamauchi

Dear Sean-san,

Thank you for your response.
I almost understand it.
When I will get the additional questions from the customer, I will ask again.

Best regards,
