Hi,
I want to test an RS485 port Txd Rxd Only
I was thinking of building another board with an RS 485 transceiver ..But this transceiver should send back what ever data it receives.
so i can test the RS485 port of my DUT by connecting it to my board.
looking http://www.ti.com/lit/ds/symlink/sn65hvd1785.pdf
I see the transceiver has both driver enable and receive enable..
Is it possible to wire the DE and RE so that both are active at the same time..
Will it work?
Thanks for any help.
