Operations (OPS) Mode Programming
lets you program CVs in DCC loco-
motives equipped with Extended Packet Format decoders while they are on the
mainline. A typical use for OPS mode programming would be to change the
acceleration 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 DCS51 can use OPS Mode Programming to change the CV value in ANY
CV, including 2 digit and 4 digit addresses, but some decoders may not accept
changing these CV’s in Operations mode.
How to use Operations Mode Programming:
1. Place the loco you want to program on the layout.
2. Select the address of the decoder that you want to program on the local
throttle of the DCS51. The decoder must be capable of operations mode
programming.
3. Press the
prOg
key until
OPS
appears in the display.
4. Press the
Cv
key and use
KeypaD
to enter the CV you want to program.
For example, to program the deceleration rate, enter
03
for CV03 which
controls acceleration. Your display will look something like this:
5. Press the
Cv
key again and use the key pad to enter the value you want to
program for the CV you selected in the previous step. For example to set
the acceleration rate to a value of 6, enter
6
. Your display will look like this:
6. Press the
Cv-Wr
key to write the data value to the selected CV.
7. Press the
exit
key when finished programming to return to normal opera-
tions.
nOte:
OPS Mode Programming on most systems is write only. OPS mode
read back requires Digitrax compatible transponding decoders and transpond-
OPS mode programming can be performed by any
DCS51 or other LocoNet throttle, such as DT402,
DT300, UT1, etc., at any time since the throttles are not
competing for usage of the single programming track.
