SN65HVD1476: How do I configuration Multi mater Full-duplex RS485?

Part Number: SN65HVD1476

Is it possible to configure RS485 in a multi-master setup with full-duplex communication using the SN65HVD1476?

If so, How do I configuration it?

    The SN65HVD1476 is a plain transceiver and works on the electrical level. It is possible to use it in a multi-master setup, but the channel access method would be implemented in whatever device is connected to the R/D/RE/DE pins.

    Hi Jooin,

    As Clemen's pointed out. The SN65HVD1476 is an transceiver only(helps to redrive the data using fully differential signals across cables). 

    The device itself can drive a signal through a cable (driver) on one channel and can receive a fully differential signal (receiver) on a completely different channel. You can set up your system to use each channel to send data and receive data at the same time using the two different channels.
