same (as per selection/allocation).
= 0: no blow-off sound played back
Start-up delay
during blow-off
Opening the cylinder valves and with it the related
blow-off sound on a real steam engine starts most
often before the engine even starts to move.
This can be imitated with CV #273 by automatically
delaying the start of the locomotive.
This effect is cancelled when a shunting function
with momentum deactivation is being activated
(see allocation of F3 or F4 in CV #124!)
= 0: no delayed start
= 1: Special setting for blow-off via speed
regulator; no start-up delay, but setting the
speed to the lowest speed step causes the
blow-off sound to be played without
powering the motor (only with 128 speed
steps).
= 2: Start-up delay in tenths of a second,
Recommendation: no value > 20 (> 2 sec)
Blow-off schedule,
start-up whistle
schedule
Constant opening and closing of the cylinder
valves in real shunting operations, that often re-
quires many short trips with associated idle times,
is usually ommited. CV #274 causes the blow-off
sound to be suppressed if the engine wasn’t stand-
ing still for the time defined here.
Value in CV #274 = time in tenth of a second!
The same stop-time is also used for the start-up
whistle!
Defines a function key to playback the blow-off
sound manually, for shunting with open cylinder
valves for example (that is the same sound pro-
grammed with CV #300 = 133 for automated play-
back).
= 4: usual blow-off key
= 0: no key assigned (use this setting if keys are
needed for other purposes).
Steam chuff
frequency
at
speed step 1
also see CV #267 in
this table
CV #354 works only if used together with CV
#267!
CV #354 compensates for the non-linear speed
measurements of the “virtual cam sensor”:
While the adjustment of CV #267 is done in the
vicinity of speed step 10 (slow but not very slow),
a correction for speed step 1 can be performed
with CV #354 (extremely slow).
= 0: no effect
= 1…127: more chuff beats in relation to CV #267,
= 255…128: less chuff beats.
Bit 1 = 1: DIESEL, ELECTRO: Start immedi-
ately even if idle sound playback is not fin-
ished.
Bit 2 = 1: DIESEL, ELECTRO: Wait for idle
sound at short stops before departure.
Bit 4 = 1: STEAM: Two stage compressor (Z1
for fast refill after coming to a stop, Z2 for
slow pressure loss compensation during
longer stops).
Bit 7 = 1: STEAM: Delay departure until start
whistle has finished playback.
Other Bits: OEM special applications (Pantos)
Bit 0 = 1: SPECIAL MX648: Function output FO1
is used for an automatic control line of an external
energy storage.
Bit 1 = 1: DIESEL-MECHANICAL: No RPM
increase when braking (see CV #364).
Bit 2 = 0: RailCom actual speed (kph) feedback in
“old” format (for MX31ZL, RailCom ID 4).
= 1: RailCom actual speed (kph) feedback in
current format (RailCom ID 7).
Bit 3 = 1: “Looped” driving sounds will be faded
out when switching to a different speed
step in order to shorten the sounds.
Bit 4 = 1: Steam chuff frequency increases slower
at high speed (non-proprotional)
Bit 5 = 1: Braking (even by one speed
step) causes the motor and turbo
sounds to decrease by on sound step.
Bit 6 = 1: Thyristor sound may be louder when
braking (even if the volume is supposed
to decrease according to CV #357); see
CV #357.
Bit 7 = 1: SPECIAL MX645: ELECTRIC: Flashes
of light (approx. 0.1 sec) on FO7 when
switch gear sound is played.
Bit 0 = 1: SPECIAL MX645: ELECTRIC: Flashes
of light (approx. 0.1 sec) on FO6 when
switch gear sound is played.
Bit 4 = 1: Faster acceleration when speed
regulator fully opened.
Bit 5 = 1: Crossfading of chuff samples
