Component Locations

Power Input

Normally, power is supplied by the attached
controller via the RJ45 jack(s.) This barrel connector
can be used to supply power if
• the DC-MP3 is more than 50' from the
nearest controller or the controller is an older
model that cannot supply enough power
• the DC-MP3 is to be connected to a PC
without using a USB485B powered adapter or
an attached lighting controller (I.e. using a
USB485 or SC485 adapter)
• the DC-MP3 is to be put on a timer or switch
to control it (See the Jumper section below in
this case)
Use a 12 VDC power brick to supply external power
to DC-MP3 if needed.

Audio Output

This is a standard 1/8" stereo mini-jack. It supplies
line-level output. You can directly plug headphones
or FM transmitter into this jack. Use an amplifier to
drive speakers.

Jumper

This jumper is put in place for two reasons
1. The DC-MP3 is connected to a PC via an
SC485 adapter and therefore needs to supply
power to SC485
2. The DC-MP3 is to be powered by the nearest
controller, the normal case
This jumper is removed when the DC-MP3 is to be
controlled by an external timer or switch and is
therefore powered through the power barrel.

Reset Button

Press the Reset button to reset the DC-MP3 or
whenever you change the Selector Switch to have
the change take effect.

SD Card Slot

The SD card is inserted into the SD card slot with
the gold connectors facing down. Press the card into
the slot until it "clicks" into place. To remove the
card, press the card into the slot and it will spring
eject.
