Programming Track

Your MTH PS3.0-equipped HO engine can function on Programming Track

outputs from DCC systems. Because each DCC system manufacturer's output

capabilities on the Programming Track differ it is recommended that you use a

DCC Programming Track Booster to perform functions on the programming track.

Simply put – try to program or read back the address of an MTH engine on a

programming track. If you can read/write the address then you won't need a

Programming Track Booster. If your DCC system can't read/write then you will

likely need a Programming Track booster. There are a few different manufacturers

of these boosters. Your local dealer can provide you with more information on

these boosters. MTH has used the DCC Specialties Power Pax with some success.

Note – An alternative to writing on a Programming Track is to simply Program on

the Main (PoM). MTH engines support PoM to write any CV on the main.

However, read back is not supported on the main. Check with your DCC system's

manufacturer to see about any limitations they may have to PoM.

So, in the above example you simply add up the values in the “Decimal Value” row

– 128+64+0+16+8 +0+0+1 = 217. You would write 217 to the CV you were

altering.

The above applies to any CV. Also, if you have a CV that already has a value

assigned that you do not want to alter but need to make additions to it, for example

CV29, you would simply add the additional bits you enabled to the existing value to

obtain the new CV value.
