Hi
I would like to have RS232 and RS485 can be choice by GPIO circuit.
I find this in TI http://www.ti.com/lit/ug/tidua80/tidua80.pdf .
If I let B short to Z, A short to Y, one 120ohm between A-B
It's also can be work?
2. Can I use SN65HVD10DR replace SN65LBC180IDRG4Q1 and use MAX3221CDBR replace TRS3223ECDWG4 ?
