UPGRADING FLASH ROM SOFTWARE VERSION/MIDIによるバージョンアップの方法
MC-505 uses the FLASH MEMORY. So the program can be update the
program by transferring the data from the upgrading disk (SMF format),
through MIDI.
NOTICE : Before executing this software upgrade(including "Factory
Preset"), save user data referring to the section "Saving and
Loading user data", if necessary. If not , the user data will be
erased.
SS Required Items
•MC-505 Version Up Disk Set (PNo. 17048669)
(The Version up disk contains the MC-505 program converted into SMF
data.
Obtain the latest version from the service center.)
•Sequencer ÅiAnything that will playback SMF will do.
•MIDI cable
SS Update procedure
1.Connect MIDI OUT of the Sequencer with MIDI IN of the MC-505.
2. Turn the power on while holding down [TEMPO/MIXER], [PTN SET]
than 16.)
While playing, a check sum appears on the display.
One=**** : Check sum of the each file.
Al=**** :Total.
After all the files have been played, compare the original checksum
(described on disk label) with the current checksum for discrepancy.
4. Perform the Factory Preset Data loading.
(See page 7(FACTORY PRESET) for more details.)
NOTICE : As for MC-505, this procedure must be carried out after
executing the update procedure.If not, some strange problem
may occur later.
The update procedure is now complete.
NOTICE/修理作業時の注意事項
1. Adjusting DBeam controller
When you replace MAIN ESCT ASSY, DBeam controller adjustment is
necessary.
1-1.Remove the bottom cover.
1-2.Connect the test probe of the oscilloscope to the Tap
Point of the MAIN BOARD.
TP 1: +TP 2: -(GND)
1-3.Adjust the voltage output from TP 1 to 0V by using
VR1.
NOTE : When you adjust the voltage, be sure to keep MC-
505 in a horizontal position, and keep any object and
strong light (fluorescent lamp etc.) away from around
the photoreceiver.
Please don't observe the voltage in a state of the
photoreceiver side down.
2. Group wires
The wirings that connect MAIN ESCT BOARD ASSY and PANEL
BOARD are tied.
This action is necessary to keep wirings from contacting with Power
Supply Unit.
Once you cut the tie, please take this action again for safety.
3.Press the [ENTER] button, then MC-505 checks the ROM-ID number.
And display shows as follows.
Check to see that the display shows as described above and then
playback the SMF data.
When the update procedure is in normal operation, [PATCH] LED will
blink.
The file names are as follows.
_000001.mid
_000002.mid
|
_000016.mid.
(For cases where program data volume is small, the file count is less
