DCC-EX Native/Serial Commands - Overview

When the DCC-EX team designed the DCC-EX EX-CommandStation they found the 'WiThrottle Protocol' too limiting and came up with a new protocol referred to originally as DCC++ but later as DCC-EX Native Serial Protocol or DCC-EX Native Serial Commands.

The EXRAIL Full Command List page contains the full list of supported commands and is automatically updated from the source code.

The Grouped DCC-EX Serial Command Reference page contains a list of supported commands, broadly group by what they relate to. This list is manually updated and may a) be incomplete and b) may lag behind the full list.

Usage

Engine Driver, EX-WebThrottle, EX-Toolbox, JMRI and a few other apps can use the more powerful DCC-EX Native Serial Protocol (rather than WiThrottle) when connecting to a DCC-EX EX-CommandStation.

Engine Driver can also use the DCC-EX Native Protocol to connect to a DCC-EX EX-CommandStation via JMRI but you need to enable the 'DCC++ over TCP Server' in the 'DCC++'' menu in Decoder-Pro.

See the WiThrottle Protocol VS DCC-EX Native/Serial Commands page for general information.
