-* Feedback can also be sent to the rotary encoder by using 2 Vpins, and sending a SET()/RESET() to the second Vpin.
+* Further to this, feedback can be sent to the rotary encoder by using 2 Vpins, and sending a SET()/RESET() to the second Vpin.
 * A SET(vpin) will flag that a turntable (or anything else) is in motion, and a RESET(vpin) that the motion has finished.
 *
-* In addition, defining a third Vpin will allow a position number to be sent so that when an EXRAIL automation or some other
-* activity has moved a turntable, the position can be reflected in the rotary encoder software. This can be accomplished
-* using the EXRAIL SERVO(vpin, position, profile) command, where:
-* - vpin = the third defined Vpin (any other is ignored)
-* - position = the defined position in the DCC-EX Rotary Encoder software, 0 (Home) to 255
-* - profile = Must be defined as per the SERVO() command, but is ignored as it has no relevance
-*
-* Defining in myAutomation.h requires the device driver to be included in addition to the HAL() statement. Examples:
-*
-* #include "IO_RotaryEncoder.h"
-* HAL(RotaryEncoder, 700, 1, 0x70)    // Define single Vpin, no feedback or position sent to rotary encoder software
-* HAL(RotaryEncoder, 700, 2, 0x70)    // Define two Vpins, feedback only sent to rotary encoder software
-* HAL(RotaryEncoder, 700, 3, 0x70)    // Define three Vpins, can send feedback and position update to rotary encoder software
-*
 * Refer to the documentation for further information including the valid activities and examples.

+// If you do not need the EEPROM at all, you can disable all the code that saves
+// data in the EEPROM. You might want to do that if you are in a Arduino UNO
+// and want to use the EX-RAIL automation. Otherwise you do not have enough RAM
+// to do that. Of course, then none of the EEPROM related commands work.

+// DEFINE TURNOUTS/ACCESSORIES FOLLOW NORM RCN-213
+//
+// According to norm RCN-213 a DCC packet with a 1 is closed/straight
+// and one with a 0 is thrown/diverging.  In DCC++ Classic, and in previous
+// versions of DCC++EX, a turnout throw command was implemented in the packet as 
+// '1' and a close command as '0'. The #define below makes the states
+// match with the norm.  But we don't want to cause havoc on existent layouts,
+// so we define this only for new installations. If you don't want this,
+// don't add it to your config.h.
+//#define DCC_TURNOUTS_RCN_213
+
+// The following #define likewise inverts the behaviour of the <a> command 
+// for triggering DCC Accessory Decoders, so that <a addr subaddr 0> generates a 
+// DCC packet with D=1 (close turnout) and <a addr subaddr 1> generates D=0 
+// (throw turnout).
