This
section
describes
the
CRC
commands
used
for
the
ProMaster
2500's
programming
electronics.
It
includes
the
following
information:
•
System

—
Explains
how
to
set
up
the
2500
programming
electronics
for
remote

operation.
Includes
information
on
entering
and
exiting
CRC
mode.
•

—
Lists
the

that
may
be
returned
while
the
2500
programming
electronics
is
being
operated
in
CRC
mode.
System
Setup
The
2500
programming
electronics
receives
CRC
commands
and
sends
responses
to
the
host
computer
through
the
RS-
232c
port
labeled
“Programmer
Port”
on
the
back
of
the
2500.
This
is
the
only
port
that
will
respond
to
programming
electronics
CRC
commands.
To
ensure
correct
operation
of
the
2500
port
with
the
host
computer,
set
the
parameters
for
the
2500
port
according
to
the
host
computer
requirements.
Halting
CRC
Operations
To
halt
any
command
or
any
ongoing
CRC
operation,
send
one
of
the
following
commands
to
the
Programmer
port
(neither
command
requires
a
).
Both
commands
act
immediately,
terminating
any
preceding
command
operation.

If
you
exit
remote
mode
using
the
Z
command,
the
2500
programming
electronics'
parameters
are
set
to
the
values
they
held
before
you
entered
remote
mode.
If
you
exit
using
Ctrl
+
Z,
the
2500
programming
electronics'
parameters
remain
at
their
current
values.
Programming
Electronics
CRC
Commands
CRC
commands
are
a
set
of
simplified
commands
for
the
2500
programming
electronics.
The
commands
are
designed
to
be
received
from
a
controlling
computer.
Because
the
commands
are
so
simplified,
they
can
be
cryptic.
