Configuring Function Mapping
Function mapping CVs allow you to reassign any
effect to any function key, enable effects to
respond automatically to direction and movement
changes, map an effect to the emergency stop
button, and gives you the option of using NMRA
“Legacy” function mapping. It’s easy to customize
function assignments to fit any operating
preference with Flex-Map function mapping
technology!
Note:
To access Indexed CV Page 1 with CVs 257-512, CV 31 (CV Index 1) must be set to a
value of 16 (default) and CV 32 (CV Index 2) must be set to a value of 1 (default).
Function Mapping with Flex-Map Technology
To complement the decoder’s wide range of effects, Tsunami2 puts you in control of all function
assignments. Flex-Map CVs determine default function assignments for Tsunami2, and allow
you to customize function keys and effects according to a simple and versatile format.
Customize Function Assignments
CVs 1.257-1.384 (Effect Map Registers) are used for function mapping. Each effect
corresponds to a CV. The value of each CV determines the F0-F28 function key used to control
that effect. Follow the steps below to use CVs 1.257-1.384 for customizing function
assignments:
1. Ensure CV 31 (CV Index 1) is set to a value of 16.
2. Enter a value of 1 into CV 32 (CV Index 2) to select Index CV Page 1 as the active
indexed CV page and enable access to CVs 1.257-1.384.
3. Access CVs 257-384 from your command station.
4. Enter a value from 0 to 28 into CVs 257-384 to map the
corresponding effect to function keys F0-F28.
5. Enter a value of 255 to disable the corresponding effect.
Refer to Table L on the next page for a list of CVs 1.257-1.384 and corresponding effects.
