MAX1482 is functional equivalent to other standard RS485 transceivers, e.g. MAX485 or SN75176. There are datasheets on the internet.

There have been countless threads on edaboard regarding RS-485 operation in general.

Although not strictly specified by the EIA RS-485 standard, the term RS-485 usually designates a half-duplex connection.
In this case, you have to achieve, that only one transmitter is enabled at a time. Some embedded processor are handling the
TX_Enable signal in the UART hardware, others need supporting software routines or auxilary hardware to perform an automatic
Tx switching.

The commuinication protocol has to control Tx access to the bus. A simple solution is by a master-slave protocol, e.g. MODBUS.

Re: max 1482

Hi, Nice to see embedded engineer from rajkot.

I would also suggest to read and understand first rs 485 topology. After understanding all this, it would be easy to deal with MAX1482.
