Gilderfluke&Co Sd-50 Audio & Show Controllers - Manual (Page 28)

c)
The next eight MIDI notes are sent to the ‘MPU Interface’ to select and trigger
audio files, mute, and otherwise control the .Mp3/.wav player.
d)
The remaining notes are used to directly select and play individual SoundFiles
stored on the .Mp3/.wav player. Only note ‘On’ MIDI commands will have any
effect on selecting and playing SoundFiles. The ‘velocity’ of the note will set the
playback level of the triggered SoundFile, if RealTime level control has been en-
abled on the .Mp3/.wav player.
The DMX/MIDI/Serial LED will be lit once MIDI is received through this port. This LED
will remain on for approximately 10 seconds after the MIDI is removed from the Sd-50/8 or
Sd-50/40. The Sd-50/8 or Sd-50/40 will stop playing any shows from the onboard flash
when a valid MIDI signal is received. It will not restart automatically if the MIDI signal is
removed.
2)
When ‘MIDI Notes Trigger Animation’ checkbox is ON, then MIDI notes are used to directly
access Animation sequences stored in the flash on the Sd-50/8 or Sd-50/40. These se-
quences in turn can access audio files on the .Mp3/.wav player, as well as controlling the
Show Control outputs. When operating in this mode:
a)
Any MIDI notes which are below the number you have set for the ‘MIDI Offset’ are
ignored.
b)
The remaining notes are used to directly select and play individual animation se-
quences stored on the Show Control half of the Sd-50/8 or Sd-50/40. These ani-
mation sequences can in turn select and play audio files and control audio levels
on the .Mp3/.wav player. Only ‘Note On’ commands are used to select and play
animated shows when operating in this mode.
The DMX/MIDI/Serial LED will be flash for 1/10 second each time a prepro-
grammed show is started by a MIDI note. The Show Control side of the Sd-50/8 or
Sd-50/40 can still accept starts though the serial port and four trigger inputs while
operating in this mode.
Net Serial Input
The Optoisolated/RS-422 switch on the bottom of the Sd-50/8 or Sd-50/40 can be in either
position. If feeding multiple Sd-50/8 or Sd-50/40, then the ‘RS-422’ position should be used.
One big disadvantage of the RS-232 serial port on the Sd-50/8 or Sd-50/40 is that only one
Sd-50/8 or Sd-50/40 can be attached to the same serial port at the same time. This is the unfortu-
nate nature of a RS-232 port. If you had a bunch of Sd-50s in the same system, this could quickly
chew up a lot of serial ports! Most of our other products use RS-422 serial ports. Along with being
able to run your wires up to a mile (RS-232 is limited to about 50 feet if the wind is blowing in the
right direction), RS-422 allows lots of devices to be attached to the same serial port at the same
time.
Because it is not uncommon to access and control a large number of controllers on the same
serial line, the DMX-512/MIDI input can be selected to turn the DMX-512/MIDI port into a multidrop
Serial network. This mode parallels the data received on the DMX-512/MIDI input pins with the se-
rial data received on the regular RS-232 serial port. The serial data is still output from the Sd-50/8
or Sd-50/40 still comes ONLY through the RS-232 serial port on the front to the unit.
This serial port can be used to select and play shows or AutoDownload shows from any point
on the network. Since it is 100% compatible with the RS-422 serial ports on all other Gilderfluke &
Company equipment, a multidrop network can consist of up to 256 Sd-50/8 or Sd-50/40 and any
