The Different Delay Settings in ESU Decoders

There are two different delay settings in LokSound decoders:

 

1)  Setting CV124 bit 2 (bit value 4) takes effect only if speed is zero and Sound Slot 1 (prime mover) is off. It's a startup delay that prevents the user from activating prime mover sound and then moving off while the prime mover is still cranking over (because that's how a real loco behaves). It’s not a fixed time value but depends on how long the start-up sequence takes.

 

2)  Separately, there's a move off delay that takes effect every time speed is zero and prime mover is already running. It prevents the loco from moving off immediately and allows a prime mover spool-up time before the loco actually moves (because that's how a real loco behaves). By default it is set to 3 seconds.

 

Effect (1) can be enabled/disabled  via bit 2 of CV124.

 

Effect (2) is a different story:

• For LokSound V4 decoders, the setting is internal to the Sound Slot 2 schedule (see T1 below, units of 0.25 second). It requires you to have a Lokprogrammer and a copy of the original sound file  as you have to change and rewrite the entire sound project.
• For LokSound Select decoders, the user can't change it because the Sound Schedule part is laced out.
• For LokSound 5 decoders, typical projects have moved this setting to SoundCV13 (CV 167). You can change this with your Power Cab or JMRI DecoderPro. (I strongly recommend that you read and write down the original value in CV167 in case the effect is unwanted and you have to revert.

Thanks to Mark Granville of the ESU Groups.io forum for reminding the forum of the differences. This was in response to a question asked.
