files onto it. Once the Mp3-50/8 or Mp3-50/40 software drivers
have been loaded onto your computer, you can plug a USB
cable from your computer to the Mp3-50/8 or Mp3-50/40. After
a few moments the Mp3-50/8 or Mp3-50/40 will appear on your
computer as a ‘removable hard disk drive’. You can then access
the SmartMedia card in the Mp3-50/8 or Mp3-50/40 just as you
would any disk that is attached to your computer. You can even
use the Mp3-50/8 or Mp3-50/40 to download pictures from the
SmartMedia card you normally use in your digital camera.
3) Power Supply: (Mp3-50, Mp3-50/8, Mp3-50/40) The power sup-
ply connections to the Mp3-50, Mp3-50/8 or Mp3-50/40 are
available on both a 2.1 mm power jack and two of the screw ter-
minal positions. For mobile, permanent or higher current applica-
tions, you may wish to use the screw terminals instead of the 2.1
mm power jack. It is less prone to being accidentally unplugged
or vibrating loose. The screw terminals are also a very convenient
place to ‘steal’ a little ‘juice’ to power the four optically isolated in-
puts.
If you are not using the onboard amplifier, the Mp3-50, Mp3-
50/8 or Mp3-50/40 can be run from any supply voltage from 9
VDC to 24 VDC. If you are using the onboard amplifier and want
to reach the maximum possible power from the amplifier, you will
need to run the Mp3-50, Mp3-50/8 or Mp3-50/40 from 24 VDC.
The Show Control outputs are powered from this supply con-
nection as well. If you are driving 24 VDC loads, then run the
Mp3-50, Mp3-50/8 or Mp3-50/40 on 24 VDC. If your loads re-
quire 12 VDC, then run the Mp3-50, Mp3-50/8 or Mp3-50/40 on
12 VDC.
The power supply connections are protected from reversed
polarity. An idle Mp3-50, Mp3-50/8 or Mp3-50/40 draws only
about ??? milliamperes. The onboard amplifier and loads which
the Mp3-50, Mp3-50/8 or Mp3-50/40 is controlling will usually
draw far more current than the Mp3-50, Mp3-50/8 or Mp3-50/40
itself. If you are using the onboard amplifier, you should allow at
least 25 Watts for it, in addition to the current for controlling your
animation loads (Mp3-50/8 and Mp3-50/40). If you hear ‘clicks’ or
clipping on your amplifier outputs, then your power supply capac-
ity may need to be increased.
4) DMX-512/MIDI Serial In: (Mp3-50/8, Mp3-50/40) Two position
Screw Terminals. This input can be selected for RS-422 (high-z) or
optoisolated (low-z) input by a switch on the bottom of the unit.
