INTRODUCTION

System
Overview
The
Columbus
Instruments
Modular
Treadmill
is
an
economical
treadmill
that
can
be
controlled
via
computer
interface
or
manually.
It
is
designed
as
a
stand
‐
alone
system
capable
of
exercising
one
to
four
subjects
simultaneously.
The
basic
system
(“Master
Lane”)
consists
of
three
separate
units:
the
Treadmill
Controller,
the
motor
assembly,
and
the
treadmill
running
lane.
Up
to
three
additional
(“slave”)
lanes
can
be
coupled
to
the
Master
Lane
to
expand
the
system
without
adding
another
controller
or
motor.
The
controller
allows
the
running
belt
to
be
adjusted
from
3
‐
100
meters
per
minute.
The
running
surface
can
be
manually
inclined
from
0
to
25°,
in
5°
increments
above
the
horizontal.
The
electric
stimulus
option
is
recommended
but
not
required.
The
electric
stimulus
can
be
individually
enabled
or
disabled
for
each
lane.
The
repetition
rate
and
the
stimulus
intensity
are
also
user
adjustable.
All
data
collection
of
animal
exercise
can
be
done
manually
from
the
front
panel
or
automatically
with
connection
to
a
PC
or
Oxymax
Indirect
Calorimeter.
The
Treadmill
Controller
allows
the
user
to
set
the
parameters
for
the
treadmill
belt
speed
and
optional
Electric
Stimulus.
A
toggle
switch
commands
the
treadmill
belt
to
“RUN”,
“STOP”
and
“ACCEL(ERATE)”,
a
new
feature
of
the
controller.
An
LCD
display
reports
the
current
speed
setting,
treadmill
belt
status
as
well
as
the
accumulated
distance
traveled.
The
optional
Electric
Stimulus
is
a
200
millisecond
(ms)
pulse
of
electric
current
adjustable
from
0.34
to
1.60
milliamperes
(mA).
The
pulse
is
presented
1,
2,
or
3
cycles
per
second
(Hertz,
Hz).
Individual
toggle
switches
associated
with
each
treadmill
control
the
application
of
the
Electric
Stimulus
to
the
shock
grids.
The
Treadmill
Software
communicates
with
the
Treadmill
Controller,
which
is
used
to
set
the
acceleration
parameters,
as
well
as,
report
the
status
of
the
treadmill
belt
speed
and
the
accumulated
distance
traveled.
Once
set,
the
acceleration
parameters
are
saved
in
the
Treadmill
Controller,
which
are
immediately
available
the
next
time
the
Treadmill
Controller
is
used
with
or
without
the
host
computer.
