EVM User's Guide: RS485FLDPLXDRCEVM
RS485FLDPLXDRCEVM Evaluation Module
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.
