13.0 Controlling Functions
The DT402 Throttle will control up to 29 (F0-F28) functions when operating in
walkaround and radio mode. When operating in IR mode the DT402 throttles
will control up to 9 functions (F0-F8). The numeric keypad is always active in
the normal
Fn
operation mode. The functions that are currently on for the
active loco will be displayed on the top line of the DT402 display. The follow-
ing figure shows an example of how the display looks when functions
0
and
1
are turned on for loco
1652
on the
R
Throttle.
13.1 Controlling Functions F0-F12
1. Determine which throttle you want to control functions on and make it the
active throttle by single clicking the
Throttle
knob or by turning the
Throttle
knob a couple of clicks.
2. If the Mode indicator in the center of the bottom line of the display
(between the loco addresses) does not show
Fn
, press the
FUNC
key once
to enter the function mode for the active throttle.
3. The DT402’s numeric keypad is always active in function mode during
normal loco operations. When the mode indicator on your DT402 shows
Fn
, simply press any number on the keypad to activate or deactivate any
function from 1 to 12. The function is on for the active loco when the
function number is displayed on the top line of the display.
Function 0 (F0)
Press the
LAMP / 0
key to toggle F0 between on and off. Each time the
LAMP / 0
key is pressed while in function mode, F0 will change from off to on
or vice-versa. The top line of the display will display a
0
when the F0 is on
and will be blank when F0 is off. F0 is most often used for reversing head
lights but can be set up for other functions as well.
Function 2 (F2)
Press the
HORN / 2
key on the numeric keypad. F2 is labeled with a whistle
icon to remind you that this is the preferred function for whistle or horn opera-
tion.
F2 is a special non-latching function. This means that F2 can be used to con-
trol a whistle or horn sound from the decoder. It will only sound when F2 is
being held down. This lets you vary the length of time that the whistle blows,
just like the prototype.
