13.4 Operations Mode Programming
Operations mode programming lets you program CVs in DCC locomotives
equipped with Extended Packet Format decoders while they are on the main-
line. A typical use for Ops mode programming would be to change the accel-
eration rate (CV03) or the deceleration rate (CV04) of your locomotives to
simulate the weight and braking capability of the train to compensate for
changing the number of cars or power units on a train.
Your DT400 can use ops mode programming to change the CV value in ANY
CV, including 2 digit and 4 digit addresses.
Ops mode programming can be performed by any DT400 at any time since the
throttles are not competing for usage of the single programming track.
Radio throttles do not need to be plugged in to LocoNet during Ops Mode
Programming. When you enter programming mode with a radio throttle,
Ops mode is the only programming mode that will be available unless you
plug in to LocoNet. IR throttles must be plugged in for Ops Mode.
How to use Operations Mode Programming
1. Select the DCC loco address that you want to program on either the L
or R Throttle. Be sure that the address you want to program is the
active throttle, the one with the blinking smoke when you enter pro-
gramming mode.
2. Enter Program Mode by pressing the PROG Key
to enter pro-
gramming mode. The display will show the last CV and CV Value
you programmed.
3. Select operations mode programming mode by pressing the PROG
Key
until the “Po” appears in the Mode Indicator area of the
LCD. If you are using an infrared or radio throttle, the display will
automatically show Po. The DT400 display will show the address
that was selected on the active throttle in the right side of the bottom
line of the display. This is the address that you are preparing to
program.
4. Use the L Throttle knob to dial up the CV you want to modify. Use
the R Throttle knob to dial up the CV value you wish to program for
the CV.
