hi
I am using a device which communicates thru rs485 half-duplex interface.The required baud rate is 19200 bps.Presently i am using the circuit (i have attached it) which uses max 232 and max 485 to do the conversion.Actually i'm in a bit of a hurry and have to do this thing in 2 days max.Also i will not be able to get any other ics besides these so i'm stuck with max232 and max485.
Some of the problems i'm facing are:
1)the device is sending back the same data i'm transmitting
2)wat software should i use ?
3)wat type of flow control should i use?
thnax a ton for seeing my post.
