RS485 Half Duplex with DOTS

What is the wright shunt that i must do to make a RS485 half duplex(2 wires).
Tx+ with Tx-
Tx+ with Rx+
Thanks in advance

Hi Thierry,

Our devices allow you to just connect the EIA485 (Two wire) lines to either Tx or Rx connection, as they are internally connected. But you can certainly interconnect the EIA485(+) to both the Tx+ and the Rx+. Then connect the 485(-) to both the Tx- and Rx- if you would like.
