11.6 Steam Chuff/Cam & Gear Rotation Trim CV133 & 134

The cam input is available for steam installations to synchronize chufng.

CV133 controls the Steam Chuff/Cam conguration in the decoder. The range

of values for this CV is 01-128.

Enable an external cam by setting CV133 to the value of 128. Install a cam on

the cam lead to provide feedback that will match chufng to the actual move-

ment of the locomotive.

To get synchronized chufng without installing a cam, Set CV 133 to a value

between 01 and 127. The factory default is 63. This lets you approximate the

diameter of the driver from 1-127 inches to synchronize the chufng. You may

need to experiment with this setting to get the best result.

CV134 controls the gear rotation trim where a value of 32 equals a 100% ratio.
