The above list includes ALL F functions that an MTH PS3 engine
could have. You are free to change any of the above listed items to
any F function position, 1-28. For example, if you your engine came
from the factory without a smoke unit but you added one at a later
date you could swap out any of the F functions, 1-28, for the Smoke
On/Off and the Smoke Volume.
So, using the example above of moving F13 to F28 here are the
steps:
1.
Refer the MTH Supported CV table to see what CV the
destination Function is assigned to. In doing so, you are looking
only for the Low Byte CV location. In this case it's Cv170
2.
Using your DCC system, bring up CV programming for
Cv170
3.
Now tell the engine which F-Function you want to write at
CV170. So, looking at the Function ID table above you can see that
Coupler Close is a value of 5
4.
Using your DCC system, enter a value of 5 for CV170 and
hit Enter. You have just re-assigned the Coupler Slack sound to F28
on your DCC controller. The engine will give you a two horn blast
indication. Note – You've also left an empty location where Coupler
Slack used to be (F13)
5.
Now you can fill that location with whichever CV you'd like.
For this example we are just going to move the Cab Chatter up to
F13 (we're just swapping F13 and F28)
6.
Since F13's Low Byte is CV140 then bring up CV
programming for Cv140
7.
Now tell the engine which F-Function you want to write at
CV140. So, looking at the Function ID table above you can see that
Cab Chatter is a value of 3
8.
Using your DCC system, enter a value of 3 for CV140 and
hit Enter. Your engine will give you a two horn blast indication
