Could SN65HVD1791D be used as Half duplex RS485 by simply shorting
A-Y ----> Then using this as 'A' terminal for Half Duplex RS485
B-Z ----> Then using this as 'B' terminal for Half Duplex RS485
or is it not designed to work in Half duplex mode?
I am seeing some issues operating this in Half Duplex mode but instead of shorting
A-Y & B-Z
If I connect 100R between A & Y
& another 100R between B & Z
then it seems to work but not reliably and I am not sure if I should really be adding 100R between the two lines for each pair!?
