being fed RealTime update messages, or the Show Control
flash memory, if shows have been programmed into the
Mp3-50/8 or Mp3-50/40.
DMX-512 transmission is limited to sixteen, eight bit wide
channels. The addresses of these DMX-512 channels are
set in one of two ways:
a) If running from RealTime updates through the RS-232
serial port, the DMX-512 data will always start with
channel ‘0’ (which is channel ‘1’ on most dimmers).
Data after the first channel will be padded with ‘0’ val-
ues through the 256th byte, and then followed by two
checksum bytes.
The Show Control Outputs, Audio Level Control,
And Repeater Control channels typically overlap with
some of the lighting control channels when operated
in this mode.
b) If running from a show file which has been AutoDown-
loaded to the Mp3-50/8 or Mp3-50/40’s Flash memo-
ry, the ‘First address’ of the downloaded data will be
the first DMX-512 channel to have your programmed
data in it. Channels before and after these sixteen
channels will be padded with ‘0’ values up until the
256th bytes sent, then followed with a two byte
checksum.
The Show Control Outputs, Audio Level Control,
And Repeater Control channels often overlap with
some of the lighting control channels when operated
in this mode. If you don’t want to do this, you can ac-
tually use all sixteen DMX-512 channels for lighting
control if you address your Show Control Outputs,
Audio Level Control, and Repeater Control channels
after the sixteen lighting control channels. Of course
this will eat up your Flash memory capacity mighty
quickly
Enable DMX-512 Reception: Turning this mode on disables
MIDI, IR Triggers and Net Serial input on the DMX-512/MIDI
serial port. Data output from the DMX-512/MIDI serial port
will be buffered and repeated, but otherwise an unaltered
version of what is received on the input.
When this mode is enabled, any valid DMX-512 will take
