Not getting any output from RS485 Transceiver, but I do see input on D (Pin 4) of the Transceiver. Not sure of utility of the DIN1 and DIN2 jumpers and the need for the Multivibrator.
Any help is appreciated to get a basic circuit working.
I do believe that the RS485 device that I am trying to comm to is Full Duplex, and I have verified that a off-shelf 232-485 converter is talking to the device fine. Just not this circuit.
Thank for any help. Or even a more simple circuit that might be more reliable. I liked this one originally due to the isolation.
