Gilderfluke&Co Sd-50 Audio & Show Controllers - Manual (Page 20)

1) ! Right (Sd-50/0, Sd-50/8, Sd-50/40)
This LED flickers to give you a rough approximation of the audio being played out of the right side of
the audio player. It is downstream of the volume processing done on the Sd-50/0, and will dim to reflect
changes in
volume level . It is upstream of the Right Volume Control Pot. Changes in the Right Volume
Control Pot will not affect the output level of this LED.
2) ! Sd Access (Sd-50/0, Sd-50/8, Sd-50/40)
This LED glows to show accesses to the Sd-card. Even when idle, this led will be flickering slightly as
the audio processor makes sure its friend, the Sd card hasn’t left it stranded.
3) ! Audio Run (Sd-50/0, Sd-50/8, Sd-50/40)
This LED will light to show that the Audio Player is currently playing back an .mp3 or .wav audio file.
4) ! Board Error (Sd-50/0, Sd-50/8, Sd-50/40)
This LED will flash to show you that the Sd-50/8 or Sd-50/40 has sensed one of the following errors:
a)
RealTime DMX-512 Update Error: The optional checksum in the DMX-512 RealTime update
didn’t agree with the data received.
b)
RealTime Serial Update Error: The checksum in the serial RealTime update didn’t agree with the
data received.
c)
Download Error: There was an error in the data being downloaded to the Sd-50/8 or Sd-50/40.
d)
Download Timeout: If the data being downloaded to the Sd-50/8 or Sd-50/40 stops midstream,
this LED will flash as the Sd-50/8 or Sd-50/40 returns itself to normal operating mode.
e)
Data Verification Failure: If you ask the Sd-50/8 or Sd-50/40 to verify the data in its flash mem-
ory, and it finds an error, it will flash this LED as well as displaying an error message on your com-
puter screen.
f)
Memory locked: If you try to clear the flash memory or send a show to the Sd-50/8 or Sd-50/40
while the Write Protect is in the ‘locked’ position.
5) ! Show Run (Sd-50/8, Sd-50/40)
This LED will light to show that the Show Control half of the Sd-50/8 or Sd-50/40 is currently running a
preprogrammed show. This LED will also flash at half of the frame rate (usually 15 Hz) when the Sd-50/8 or
Sd-50/40 is receiving RealTime update data either through the DMX-512 or serial ports. During flash mem-
ory downloads, this LED will alternate on each 256 bytes of data received. At the normal 9600 baud serial
rate, this is about one Hz. This LED flashes at about the same rate when loading files from the Sd/MMC,
even though the data is being loaded much more quickly.
6) ! DMX/MIDI/Serial (Sd-50/8, Sd-50/40)
This LED will light to show that the Sd-50/8 or Sd-50/40 is receiving RealTime Update data through the
DMX-512 , MIDI , RS-232 or RS-422 serial ports. If the Sd-50/8 or Sd-50/40 is receiving show starts from
MIDI input, then this led will flash for about 1/10th of a second each time a ‘start’ happens. During flash
memory downloads, this LED will flash alternately with the Show Control Heart LED at twice the normal
heartbeat rate.
