world for controlling all kinds of theatrical equipment (fans, strobes, chain winches, wiggle lights,
etc.).
You can address your Sd-50/8 or Sd-50/40 to respond to any address between 0 and 511. The
Sd-50/8 or Sd-50/40 will support all 512 possible DMX-512 channels.
If you have NOT selected DMX-512 checksums, the ‘Mp3 Config.exe’ will allow you to set the
addresses for DMX-512 to any address from 1 through 512. Address ‘1’ is equivalent to address ‘0’
if you were using checksums.
If you have enabled the DMX-512 checksum on PC•MACs, the 257th and 258th addresses are
used for transmitting a checksum. The Sd-50/8 or Sd-50/40 will automatically sense the presence
of the checksums and use them to verify that the data received from has no transmission errors in
it. Once the Sd-50/8 or Sd-50/40 hear checksum data coming through, it will lock on this feature,
and not update the outputs on any frames of data that don’t have a valid checksum in them. If you
address a light dimmer or other DMX-512 device to addresses 257 or 258, you will see this verifi-
cation data displayed as a flickering pattern.
Even though the DMX-512 standard calls for 512 channels of data, the DMX-512 transmission
from PC•MACs is currently limited to 256 eight-bit wide channels. PC•MACs will be upgraded to
support more channels in the near future.
The Sd-50/8 or Sd-50/40 will stop playing any shows from the onboard flash memory when a
valid DMX-512 signal is received.
You can optically isolate a DMX-512 signal coming into one Sd-50/8 or Sd-50/40, then feed
multiple Sd-50/8s, Sd-50/40s, or other DMX-512 equipment with the DMX-512 output from this
unit. In this way, the upstream DMX-512 is optically isolated from the downstream DMX-512. All of
the ‘downstream’ Sd-50/8s or Sd-50/40s should have their inputs set for RS-422. Note that the
DMX-512 will be delayed by a portion of a frame’s time while going through the first Sd-50/8 or Sd-
50/40. You don’t want to feed the DMX through too many units because of this delay.
MIDI Notes Input
The
of the Sd-50/8 or Sd-50/40 must be in the optoisolated/Low-z posi-
. The MIDI should be fed to the Sd-50/8 or Sd-50/40 as follows:
MIDI pin #1 = no connection
MIDI pin #2 = no connection
MIDI pin #3 = no connection
MIDI pin #4 into - DMX/MIDI In
MIDI pin #5 into + DMX/MIDI In
The Sd-50/8 or Sd-50/40 will respond to MIDI ‘Note On’, ‘Note Off’, ‘Reset’, ‘All Notes Off’ and
‘All Sounds Off’. Running commands for ‘Note On’ and ‘Note Off’ commands are also accepted. All
other defined MIDI commands will be received and promptly ignored. There are two ways the Sd-
50/8 or Sd-50/40 can be configured to respond to MIDI Note commands.
1) When ‘MIDI Notes Trigger Animation’ checkbox is OFF, then MIDI is used to directly ac-
cess the Show Control Outputs and .mp3/.wav audio files:
a) Any MIDI notes which are below the number you have set for the ‘MIDI Offset’ are
ignored.
b) The next eight (Sd-50/8) or forty (Sd-50/40) MIDI notes are mapped directly to the
8/40 Show Control outputs. These can be used to ring mechanical bells or control
animation directly from MIDI notes.
