 #### hardware setup
 
-The DMX output required the use of a MAX485 transceiver connected to the TX-pin of the ESP in order to produce DMX output.
+The DMX output required the use of a MAX485 / SN 75176 transceiver connected to GPIO2 of your ESP. As of now, the pin is hardcoded inside of WLED (see below).
 
 I am currently working on an open source PCB design to go along with this feature.
 
 For information about the use of DMX with ESP8266, you might like to read [this](https://robertoostenveld.nl/art-net-to-dmx512-with-esp8266/) tutorial by [Robert Oostenveld](https://robertoostenveld.nl/). Note this is just background information about the hardware and you do not need any of the code listed here when using WLED output.
 
-If you need to use another pin for output than the TX-pin, you'll need to change this in the ESP-Dmx library itself. This setting is located in src/dependencies/dmx/ESPDMX.cpp on line 31.
