m)! Display Config. from Sd/MMC
This displays a second page of configuration information. See the next section of the manual for the commands
available on the ‘configuration’ page.
o) ! Reload Defaults
This reloads the default values for all the animation variables. It does not affect the variables used to trigger
sounds. These are set through the ‘Mp3 Config.exe’ program. Any Sd/MMC flash card that is inserted into the Sd-
50/xx will be checked for a valid configuration file. It the Sd-50/xx finds a valid configuration file, and it is different
from what is already loaded into the player, it will be read from the Sd/MMC flash card and used to configure the
card.
p) ! Play a Show
This command is available ONLY if ShowFiles have been loaded on the Sd-50/8 or Sd-50/
40.
This command is used to request and play a specific show with the ‘looping’ flag cleared. If the currently run-
ning show (if any) is NOT steppable, The Sd-50/8 or Sd-50/40 will confirm with you that you do indeed want to start
another show. At the end of the show the Sd-50/8 or Sd-50/40 will sit and wait for the next ‘start’ or ‘loop’ command.
Do NOT use this command for controlling the Sd-50/8 or Sd-50/40 except during testing. Use the equivalent Serial
Port command instead.
s) ! Stop Show
This command is available ONLY if ShowFiles have been loaded on the Sd-50/8 or Sd-50/
40.
This command stops any show which is playing or looping immediately. The Sd-50/8 or Sd-50/40 will sit and
wait for the next ‘start’ or ‘loop’ command. Do NOT use this command for controlling the Sd-50/8 or Sd-50/40 ex-
cept during testing. Use the equivalent Serial Port command instead.
u) ! Set ServoMotor Endpoints
This command is the only way to adjust the electronic travel endpoints for any model
airplane-style ServoMotors used with a Sd-50/8 or Sd-50/40.
Unlike ALL of the other serial configuration commands, the ServoMotor ʻEndpointʼ settings
will remain in effect as other Sd/MMC flash cards with different Sd-50.cfg files on them are in-
serted into the player.
If you have to manually enable the ServoMotors before adjustment, this setting may not be
there after you change to other Sd/MMC flash cards with different Sd-50.cfg files on them.
Whether individual ServoMotor PWM outputs are enabled or not is normally set using the ʻMp3
Config.exeʼ program, and stored in the Sd-50.cfg files.
Model Airplane-style ServoMotors use a Pulse Width Modulated control signal. This is a series of pulses sent to
each ServoMotor with a positive pulse width (nominally) between .001 and .002 seconds (1.0 ms to 2.0 ms) to give
a 90º rotation on the ServoMotor’s output shaft. These pulses are sent to each ServoMotor fifty times each second.
A 1.0 ms pulse tells the ServoMotor to ‘retract’ to its ‘minimum’ position. A 2.0 ms pulse width tells the ServoMotor
to ‘extend’ to its ‘maximum’ position. A pulse width of 1.5 ms would tell the motor to move to the ‘halfway’ position.
