Hi Everyone!

 

I would like to ask for a help about adm2587 interface and pull-down/pull-up resistors on the pins.

My interface is viewable on the attachment. Now the receiver is working, but the transmit does not send data, only 0.

What is the problem? I connect A and Y to A+,  B and Z to B- to my RS485 USB CONVERTER.
