Programming on the Main (PoM)

The Native DCC-EX Protocol allows Engine Driver to read and write CVs of decoders on both the Main ona Prog tracks. The Native DCC-EX Protocol is only available when connectd to a DCC-EX EX-CommandStation and is discussed on the Features when using the Native Protocol when connected to a DCC-EX EX-CommandStation page.

The WiThrottle Protocol, which is used for connecting to Command Stations other that the DCC-EX EX-CommandStation, does not provide for any CV programming.

However it is possible to use a feature implemented in some system to do programming on the main (PoM) to write to CVs (not read).

Important

This feature only works on a very small number of DCC Command Stations. It works by sending a hex packet to the DCC Command Station.

To use this feature, enable the Show WiThrottle PoM Page preference.

Write CVs of decoders on the Main Track

Note that you cannot read CVs or DCC Addresses on the main track. You can only write CVs of a specified loco (DCC Address).

To write a new CV value, enter the DCC address of the loco you want to change, enter the CV number into the ‘CV’ field, enter the new value in the ‘Value’ field and click Write

Optionally, you can use the NRMA CVs pulldown to select a common CV from a list. This just enters the appropriate CV number in the ‘CV’ field.
