The analog mode conversion feature is very convenient if you plan to run

your Digitrax decoded locomotive on regular DC layouts. With analog mode

conversion enabled, the decoder will automatically begin operating as a DC

locomotive when no DCC signal is detected by the decoder. This means that if

you place your Digitrax decoder equipped loco, with analog mode conversion

enabled, on a regular DC layout, it will run on the DC layout. Disabling ana-

log mode conversion can be useful too as the following example illustrates:

Brake Generator Example:

If you disable the analog mode conversion feature in a decoder, when DC

power is present the locomotive will stop. This gives you a very inexpensive

way of generating a “brake section” for stopping DCC locomotives in front of

red signals.

By disabling analog mode conversion in the decoder, a relay can supply DC

voltage to a track section in front of a red signal to slow and stop a locomo-

tive in the brake section. When the signal turns green, the relay can restore the

DCC track signal, and the locomotive will restart. The decoder will slow to

a stop and restart at its programmed deceleration and acceleration values. In

addition, if you are using a decoder with FX

functions, the locomotive’s lights

and functions will remain active when stopped on the DC brake section as long

as DC power is supplied to the track while the loco is stopped.

You can use your DCS100’s second DCC output to set up a braking section.

See our website www.digitrax.com Tech Support Depot for instructions for set-

ting up a braking section with DCS100.

7.2.2 Determining CV Value To Program Into CV29

The value you program into CV29 will affect many important decoder charac-

teristics. Each of these characteristics is controlled by a “software switch.” This

switch is either on or off depending on the CV value programmed. There are

three ways to determine the value to program into CV29.

The easiest way to determine this value is to use our on-line CV calculator at

www.digitrax.com/support/cv/. TABLE IV details the CV value for each com-

bination of features.

Our on-line CV Calculator and the Digitrax Tool Box App for mobile devices

make this calculation easy, too.
