1. Call up your Middle engine (address 2 in the example)
2. Since you want to have the Middle engine respond to F3 only then write a value
of 4 (CV21, bit 2 = ON)
3. Call up your Rear engine (address 3 in the example)
4. Since you want to have the Rear engine respond to the Start-Up/Shut Down
(F3) and Rear Coupler (F8) functions you want to write a value of 132 to CV21
Your engines are now set up according to the example above.
You will note that there is no F0 in CV21. This is because that function (FL) is
controlled by CV22. Please refer to the Advanced Consisting section for more
information regarding CV22.
Programming Track
Your MTH PS3.0-equipped 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.
