SPD
Pressing the SPD softkey enables the dis-
play to show up to 128 speed steps (0-127).
MOM
Pressing the MOM softkey allows you to
set the Momentum of an individual engine
or a lash-up.
REL
Pressing the REL softkey enables Relative
speed stepping. This is particularly useful
when operating items such as Crane Cars
that have 360 degree movement. Rolling
up on the thumbwheel is the same as spin-
ning the knob clockwise on the CAB-
1/CAB-2 remote, while rolling down on
the DCS thumbwheel is the same as spin-
ning the knob on the CAB-1/CAB-2
remote counterclockwise.
