NOTE - CV21 is ONLY used when you have some value other than 0 written to
CV19. If CV19 = 0 then the values of CV21, CV22, CV23, and CV24 are not used
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.
