I'm trying to interface RS-422 data to the UART on my MCU (TM4C1294ncpdt) to send it through its ethernet interface.

Can anyone help me with how to convert the RS-422 differential signal to be read by the UART?

circuit schematic or what components do i need to do this?


There are plenty of standard RS422-to-LVTTL conversion ICs available, so this should be straightforward.

Have a look at the following devices. Their data sheets should guide you on how to connect them to you UART's serial data output (TXD) and serial data input (RXD):

Maxim MAX3086

Texas Instruments family SN65HVD30 to SN65HVD35 Search TI website for data sheet 'SLLS665K'

  • \$\begingroup\$ What should I look for exactly in the datasheet ? Or would a RS422 to RS232 conversion ,and then rs232 to ttl be better? \$\endgroup\$ – Nidhi Jan 13 '17 at 16:22
