Macro Recorder Control (Continued)
Record Mode
The macro recorder allows the locomotive operator the ability to record most events as they
occur during a session. An event is defined as a locomotive action such as activating sounds or
throttle control. A session is defined as a time duration running the locomotive on a layout. The
following events are not recorded:
Horn Frequency Shift
Record Macro Event
Emergency Stop
Pressing Emergency Stop during a macro record or play session stops the recording or playback.
Also, using the direction change while the locomotive is moving uses up the macro recording
space quickly.
Activate the macro recorder by pressing F27 (default) or whatever key has been defined to start
the macro recorder. The front light flashes and if the sound is on, the sound mutes. Once the
front light stops flashing, the macro recorder is actively recording events. Stop recording by
pressing F27 (default) or whatever key has been defined to start the macro recorder. The rear
light flashes and if the sound is on, the sound mutes. Writing 16 into CV8 saves the macro
permanently. If desired, CV245 bit 4 may be set and the macro will be automatically saved after
the rear lights stop flashing.
Each event consumes 2 macro memory locations, one location for the event and one for the time
the event occurred. A total of 1020 events may be recorded. The throttle event consumes macro
space quickly. Care should be exercised to minimize unnecessary throttle events (Use fast
increment/fast decrement features; use 28 speed step mode). Horn events are recorded at .25
second accuracy and all other events are recorded at 1 second accuracies. Fractional time units
are added to the next event once they reach .25 seconds for horn events or 1 second for other
events.
A real time counter is kept and records the last throttle zero event in the macro relative to the
start of the record session. The resolution of this timer is .025 seconds. During macro playback,
CV239 may be adjusted to set the loop time closer, giving more predictable loop repetition.
CV239 allow adjustments in .1 second intervals. This adjustment corrects the locomotives loop
end point and is negative only. The correction allowed is 25.5 seconds. If the locomotive loop
