KB941: CV49, CV50, CV61 - Setting Up Configurable Strobes

This article was last updated on Oct. 18, 2010, 6:23 p.m. | Print Article | Leave Feedback

Configurable strobes are set up using CV's 49, 50 and 61.

Configurable strobe function leads can be programmed with a limited number of simulated lighting effects similar to FX effects but without as many options. Configurable strobes are offered in those few Digitrax decoders where there was not enough "code space" to provide full FX features.

CV49 controls F0 Forward, the white function lead.

CV50 controls F0 reverse, the yellow function lead.

CV61 enables the configurable strobe operation.

To set up configurable strobe lights:

1. Program CV61 with the CV value "01" to enable configurable strobe operation.

2. Program the CV value for CVs 49 & 50 (the Configurable Strobe CVs) consists of 2 digits in a hex number that are determined as follows:

Configurable Strobe(CV49 & 50)

CV Value first digit

Light is active when

1x

Loco is in reverse direction

2x

Non directional function will be on in either direction



The first hex digit controls the conditions when the light will be active.


The second digit of the hex value controls the effect generated by the blinking of the light

Configurable Strobe(CV49 & 50)

CV Value second digit

Configurable Strobe

Effect Generated

x1

Simulated Firebox Flicker

x2

Simulated Mars Light

x3

Blinking Headlight

x4

Single Pulse Strobe

x5

Double Pulse Strobe

x6

Simulated Rotary Beacon



For example if you program CV49 to a value of x46 hex, the light on the white lead will be on no matter which direction the loco is traveling and will be blinking with an effect similar to a rotary beacon.
