APPENDIX:
SERIAL
COMMUNICATIONS
FOR
THE
TC
1
TEMPERATURE
CONTROLLER
7/26/2013
This
document
provides
the
serial
communications
protocols
for
version
1.0
of
the
firmware
on
the
TC
1
family
of
controllers:
TC
1
/t2
–
for
the
t2,
single
temperature
controller
TC
1
/t2x2
–
for
the
t2x2,
dual
temperature
controller
for
sample
and
reference
TC
1
/Turret
6
–
for
the
Turret
6,
6
‐
position
turret
The
version
number
and
the
ID
(see
below)
are
shown
briefly
on
the
display
when
the
temperature
controller
is
turned
on.
All
functions
of
the
temperature
controller
can
be
managed
from
a
computer,
using
the
command
set
described
below.
If
you
purchased
your
unit
as
a
component
of
a
spectrometer
from
certain
manufacturers,
this
feature
may
be
implemented
through
traditional
RS232
serial
connectors
on
the
computer
or
the
spectrometer
and
on
the
controller.
In
this
case
they
will
be
connected
by
a
standard
15
‐
pin
serial
extension
cable
(male
connector
on
one
end
and
female
on
the
other).
No
driver
installation
should
be
needed.
Otherwise
the
serial
linkage
will
be
established
through
a
USB
connection
between
the
computer
and
the
controller.
In
this
case
the
controller
includes
electronics
which
convert
the
USB
connection
to
a
serial
communications
port.
However,
for
the
port
to
be
available
to
programs
on
the
computer
it
will
be
necessary
to
load
driver
software.
It
is
important
that
the
driver
software
be
loaded
before
connecting
a
USB
cable
between
the
controller
and
the
computer.
Contact
Quantum
Northwest
for
further
information.
Quantum
Northwest
can
provide
a
control
program
written
specifically
for
control
of
all
functions
of
the
temperature
controller.

In
programming
for
the
TC
1
controller,
one
must
adhere
to
the
conventional
notation:
8/N/1.
Baud:

None
For
many
of
the
commands
listed
below
the
controller
returns
information
in
response
to
the
command.
All
commands
and
responses
are
delineated
by
left
and
right
square
brackets
(
[
]
).
Any
text
sent
to
the
controller
not
enclosed
within
brackets
will
be
ignored.
In
this
document
an
ellipsis
(……)
is
used
to
distinguish
responses
from
commands.
[command]
Purpose
of
the
command
(sent
to
the
controller).
......[response]
Meaning
of
the
response
(received
from
the
controller).
