Hi team,
I need some clarity on SN65HVD1473 RS-485 transceiver.
•Can I use the above IC in Half duplex mode by shorting its differential pins (ie; A with Y , B with Z) .
Since my master has 2 wire output(half duplex) and the slave has four wire (full duplex) and I cant alter this.
•If half duplex is possible then what are necessary things(protection, series termination) that need to be done in the circuit to work fine? Can I get any reference(application note, schematics) where these kind method is employed?
•How the IC will get to know that whether to transmit or receive , What should be the status of the RE and DE pins?
Please help me out in this.
Regards,
Karthik
