Description

The RS485FLDPLXDRCEVM is an EVM from TI that allows quick prototyping of our Full Duplex RS-485 Transceivers in a DRC package. The board allows for testing of single and differential ended communication with potential modifications such as changing the termination resistance or adding a common mode bias to the bus to simulate ground potential differences that can be seen in systems with long cables that share a ground line with high current capacity. The board comes preinstalled with a THVD2412DRCR which allows full duplex communication at up to 250kbps powered by a 3 V to 5.5V power connection on VCC. The board also supports testing of systems with separate EARTH planes separate from the device ground reference plane.
