Connection Timeouts
The
Ethernet
link
times
out
and
disconnects
after
a
designated
period
of
time
of
no
communications.
B
y
default,
this
timeout
value
is
set
to
5
minutes
but
the
value
can
be
changed.
See
the
Configur
e port
timeout SIS command
.
NOTE:
Extron
recommends
leaving
the
default
timeout
at
5
minutes
and
periodicall
y
issuing
the
Quer
y
(Q
)
command
to
keep
the
connection
active
or
disconnecting
the
socket
and
reopening
the
connection
when
necessar
y
.
Number of Connections
A
switcher
can
have
up
to
200
simultaneous
TCP
connections,
including
all
HTTP
sockets
and
Telnet
connections.
When
the
connection
limit
is
reached,
the
switcher
accepts
no
new
connections
until
some
have
been
closed.
No
error
message
or
indication
is
given
that
the
connection
limit
has
been
reached.
To
maximize
performance
of
y
our
switcher,
keep
the
number
of
connections
low
and
close
unnecessar
y
open
sockets.
Verbose Mode
Telnet
connections
to
a
switcher
can
be
used
to
monitor
for
changes
that
occur
on
the
switcher,
such
as
front
panel
operations
and
SIS
commands
from
other
Telnet
sockets
or
a
serial
port.
For
a
Telnet
session
to
receive
change
notices
from
the
switcher,
the
Telnet
session
must
be
in
verbose
mode
1
or
3.
See
the
Set verbose mode SIS command
.
In
verbose
mode
3,
the
Telnet
socket
reports
changes
using
messages
that
resemble
SIS
command
responses.
Establishing a USB Port Connection
A
standard
USB
cable
and
the
Extron
DataViewer
utilit
y
,
version
2.0
or
newer,
can
be
used
for
connection
to
the
DMS
switcher
Configuration
port.
The
USB
cable,
available
at
an
y
local
electronics
store,
should
be
terminated
on
one
end
with
a
mini
USB
B
male
connector
NOTE:
Before
y
ou
use
the
USB
port
for
the
first
time,
install
the
USB
driver
on
y
our
computer.
The
simplest
wa
y
to
do
this
is
to
install
version
8.0
or
newer
of
the
Matrix
Switchers
Control
Program
and
then
run
the
Found
New
Hardware
Wizard.
See
Installing the Program
and
First-time
Connection Considerations
.
Host-to-Switcher instructions
The
switcher
accepts
SIS
commands
through
its
serial
port,
its
USB
port,
or
its
LAN
port.
SIS
commands
consist
of
one
or
more
characters
per
command
field.
The
y
do
not
require
an
y
special
characters
to
begin
or
end
the
command
character
sequence.
Each
switcher
response
to
an
SIS
command
ends
with
a
carriage
return
and
a
line
feed
(CR/LF
=
]
)
,
which
signals
the
end
of
the
response
character
string.
A
string
is
one
or
more
characters.
NOTE:
The
table
that
begins
on
the
next
page
is
a
partial
list
of
SIS
commands.
For
a

listing,
