CP750 Digital Cinema Processor Manual
Remote Control and Monitoring
•
The
Ethernet
connector
supports
direct
and
switched
Telnet
connections
to
port
61408.
The
system
accepts
20
simultaneous
connections
on
the
TCP
port
concurrent
with
one
on
each
of
the
other
ports.
The
21st
TCP
connection
causes
the
oldest
TCP
session
to
disconnect,
and
sends
a
warning
message
to
the
client.
•
The
Remote
RJ
‐
45
connector
operates
at
9600
bps
with
8
data
bits,
1
stop
bit,
no
parity,
and
no
flow
control.
Characters
are
not
echoed
back
to
the
controller,
and
the
Ethernet
and
Remote
connections
do
not
support
terminal
control
characters
such
as
<Backspace>.
The
RS-232
connector
does
support
terminal
control
characters
and
is
therefore
the
most
user
friendly.
7.2.2
Command Syntax
Command
parsing
is
not
case
sensitive.
White
space
is
ignored
on
input
lines.
Most
commands
consist
of
a
parameter
name
followed
by
a
space
and
a
value.
cp750.sys.input_mode dig_2
instructs
the
system
to
use
digital
input
2.
The
system
responds
with
status
text
verifying
that
the
value
has
been
set:
cp750.sys.input_mode dig_2
Queries
consist
of
a
parameter
name
followed
by
a
space
and
a
question
mark.
cp750.sys.input_mode ?
asks
which
input
the
system
is
currently
using.
The
system
responds
with
status
text
for
the
specified
parameter.
cp750.sys.input_mode dig_2
If
you
send
an
unrecognized
value,
the
system
takes
no
action
and
returns
parameter
status.
If
you
send
an
unrecognized
parameter,
the
system
returns
a
blank
new
line.
No
error
messages
are
generated.
There
is
also
a
small
set
of
single
word
commands
such
as
help
,
status
,
and
exit.
