This
tool allows
you to

When
run,
the last

is displayed.
Press

EEPROM
Initialize Enable
(15)
Performing
this function
sets a
flag in
the
SRAM
(U9)
that
enables the
EEPROM
(U7) to be
initialized when
you
return
to
normal
operating mode
by
selecting Test
9. This initialization
writes
the
16
factory
presets
8
times
into
120 user
registers.
It also
initializes
any corrupt registers variables,
sets
the
DRAM
size to
64K,
disables the
MIDI
Bypass, setsthefootswitchto
“momen-

sets
the
MIDI
channel
to

,
clears
all of the “Cleared Register Flags”
and
turns the
OMNI Mode
off.
MIDI
Troubleshooting Tool
(ALT
1)
This
is a
simple troubleshooting tool that continuously
outputs
a
MIDI clock
message
(F8 hex)
to
the
MIDI
OUT port. To
run
this tool,
press
STORE/
CLEAR.
The
display
will
indicate
r.
On
a scope
this looks

pulse.
Press
PARAMETER/LEARN
to
disable Reflex’s ability
to
detect
incoming
MIDI
clock. To
exit the tool,
press
STORE/CLEAR or
PARAMETER/LEARN.
To return
to
normal operating
mode,
select
9
with the
REGISTER/PRESET
knob, then press
STORE/CLEAR
again.
Sinewave Generator (ALT
2)
This
is
another
troubleshooting
tool that
outputs a
digitally-generated
sinewave
to
the
DAC
(both
outputs).
When
selected,
the display
indicates
either 1
.
(if
the
REGISTER/PRESET
knob is
in
the
RICH
PLATE position) or
4.
(if
the knob
is
in
any other position). The
1
represents
1kHz
and
the
4
represents 440Hz.
To
output
a
sinewave
at the
indicated
frequency, press
any key.
An r
is
displayed.
Press
any key
to
exit
the
generator.
Because
the
sinewave is
digitally
generated the distortion
at
the output should
be
the
lowest
the
system
can
produce (typical
.01%).
Output
level is
full
scale
for
the
converter
(5.5dBu
typical with
the OUTPUT
level
CW).
Set DRAM Size
(ALT
4)
This
tool
allows
you to set
the
DRAM
size
to
64K, 256K
or
1
Meg
in
the
event
that the installed
DRAM
is changed. Currently,
Reflex has 64K
DRAM
installed.
DRAM size
is stored
in
the
EEPROM
(U7)
and
read each
time
the
DRAM
test
is
run. When
the
EEPROM
is
initialized,
the
DRAM size
is set
for
64K
and stored
in
the
EEPROM. The
rule of thumb
here is
that
either
the
EEPROM must
be
initialized
before running the
DRAM
test
or the
operator
must
set
the
size. The size
is
set
manually
using diagnostics
4A (alternate
mode).
When selected, this
diagnostic displays a
numberfrom
0-3
which
can
be
changed
by
turning the VALUE knob. The size
is
set
(written
to
the
EEPROM) when STORBCLEAR,
PARAMETER/LEARN or
REGISTER/
PRESET
is
pressed.
The
+
will flash
on
the display followed
by
4. The
values
represent
the
DRAM
sizes
as
follows:
0
=
64K
1
=
