• Lock Step – This option causes the DC-MP3
to send all controller commands ahead of
time for the next time slice and then give a
global "everybody do their commands"
command. This has the effect of eliminating
the communication line delays when you
have a large number of controller/channels.
This is a recommended setting. This option is
not supported by CTB08 and MC-P cards and
requires firmware version 3.0 or above for 16
channel controller cards.
• Add file to SD card to set the MP3 player's
internal clock – This option puts a file with the
current time on the SD card. The MP3 player
will set its real time clock to this time when the
SD card is inserted into the player for the first
time. Don't take too long to transfer the card!
The MP3 player should be powered up for at
least 15 minutes before using this option so
that the backup capacitor will be fully charged
and can keep the real time clock going when
power is removed from the MP3 player.
• Comm Speed – Use these radio buttons to
select the RS485 communications line speed.
Use the slowest speed that successfully runs
your show. If the speed you select is not fast
enough to run your show, the red E LED will
light. This indicates that the DC-MP3 has
fallen at least one tenth of second behind in
getting controller commands out on the
RS485 network link.
Use the Select Drive with the SD card section to
choose the SD card. The drop-down menu will
default to the first removable drive on your system. If

you forgot to plug the SD card/SD card writer into
the PC, do it now and click the Refresh Drive List
button.
Finally, click the Place Show on the SD Card
button to write the current Show, Schedule and
possibly current time to the SD card. You will see
this window when it is done:
Repeat the above process for each show to be
transferred to the SD card.

(Hardware Utility <1.6.4)
This section describes how to use older Hardware
Utility versions (1.5.8 to 1.6.3) to set up and
schedule show(s) for the DC-MP3. These Hardware
Utility versions do not support the trigger inputs. You
must have:
• At least version 2 of the DC-MP3 firmware,
see the section DC-MP3 Firmware Versions.
• Hardware Utility version 1.5.8 or later, see the
Hardware Utility Version section.
• The USB SD card reader/writer plugged into a
USB port on your PC with the SD card in it, or
have the SD card in your machine's built in
reader/writer.
• It is not necessary to have the DC-MP3
connected to your PC to transfer a set of
scheduled shows to the SD card.
