Diesel Version 5:CV 16 0 258

CV 16.0.258 - Startup Delay Timer

Two byte CV (257:258) - defines the maximum delay time (in milliseconds) the decoder will wait and look for a non zero DCC speed packet when powering up. During this delay no sound will be played.
If the decoder sees a non zero speed packet during this time it will skip the startup sound and go right to playing the engine sound

This is useful in cases where the engine was moving along and hits dirty track and resets.
If the delay time is large and the startup sound still plays consider adjusting the command stations stack so that speed refresh packets are sent more often.
