You can construct a gateway between RS232 and RS485 interfaces, but usually you will see the RS485 protocol connecting directly to USB, GSM or Ethernet ports. You can do this by using a bus terminator, moving a switch or with a small resistor screwed onto a terminal.Ĭare must be taken to ensure that the correct interface is being used as the RS485 and RS32 protocols are not completely compatible. This eliminates the need to have several interfaces available when querying multiple devices. One of the reasons that RS485 interfacing is employed in industrial settings is its ability to serve several devices attached to the same bus. The two protocols use different electric signals to enable data transmission. RS485 is a protocol similar to RS232 that is used to implement serial data communication.
