PRELIMINAR
Y
X1@
= MLC’s name. The name is a text string of up
to 24 characters drawn from the alphabet
(A-Z), digits (0-9), and minus sign/
hyphen (-). No blank or space characters
are permitted as part of a name. No
distinction is made between upper and
lower case. The fi rst character must be
a letter. The last character must not be a
minus sign/hyphen.
X1#
= Local date and time format
Set
format (MM/DD/YY-HH:MM:SS).
Example: 01/18/05-10:54:00.
Read
format (day of week, date month year
HH:MM:SS). Example: Tue, 18 Jan 2005
18:19:33.
X1$
= IP address (xxx.xxx.xxx.xxx). Leading zeros
in each of four fi elds are optional in
setting values, and they are suppressed in
returned values.
MLC’s default address: 192.168.254.254
Default broadcast address:
255.255.255.255.
X1%
= E-mail domain name; for example, extron.com
X1&
= Time in tens of milliseconds to wait until the
fi rst response character is received via a
serial port before terminating the current
receive operation (Default = 10 = 100 ms,
max. = 32767.) The response includes
leading zeros.
N For commands that use both
X1&
and
X2)
, both
variables must be zero or both must be non-zero.
In the RS (send data) command,
X1&
is optional
as long as
X2)
is also missing.
X1*
= Hardware (MAC) address (xx-xx-xx-xx-xx-xx)
(00-05-A6-xx-xx-xx)
X1(
= Subnet mask (xxx.xxx.xxx.xxx). Leading
zeros are optional in setting values in each
of four fi elds, and they are suppressed in
returned values. Default = 255.255.0.0.
X2)
= Time in tens of milliseconds to wait between
characters being received via a serial port
before terminating the current command
or receive operation. The response
includes leading zeros.
(Default = 2 = 20 ms, max. = 32767)
N For commands that use both
X1&
and
X2)
, both
variables must be zero or both must be non-zero.
In the RS (send data) command,
X1&
is optional
as long as
X2)
is also missing.
Symbol defi nitions
]
= CR/LF (carriage return/line feed) (hex 0D 0A)
}
= Carriage return (no line feed, hex 0D)
(For URL-encoded commands, use the
pipe character,
|
, instead.)
•
= Space
character
|
= Pipe (vertical bar) character
E
= Escape key (hex 1B)
(Use W instead of Esc for Web browsers.)
X!
= Specifi c port number or relay number (01 – 99)
Relays:
1 = relay 1, 2 = relay 2, 3 = relay 3,
4 = relay 4, 5 = relay 5, 6 = relay 6
Other ports:
1 = rear host (Confi g/RS-232 port)
2 = front panel Confi g port
3 = slaved switcher (MLS port)
4 = display/projector port
(Proj RS-232/IR)
5 = IR/Serial port A
6 = IR/Serial port B
7 = IR/Serial port C
X@
= Command data section.
N For Web encoding only: data is directed to
the specifi ed port and must be encoded (URL
encoding) if it is non-alphanumeric. Change
any non-alphanumeric character (%, +,
|
,
}
, etc.) within the data section into the
corresponding hexadecimal equivalent, %xx,
where xx represents the two-character hex byte.
For example, a space (hex: 20) would be encoded
as %20 (hex: 25 32 30) and a plus sign (hex: 2B)
would be encoded as %2B or hex 25 32 42.
X#
= Greenwich Mean Time (GMT) offset value
(-12.00 to +14.00) represents the time
difference in hours and minutes
(+/-hh:mm) relative to Greenwich,
England. The leading zero is optional.
For example, 5:30 = 05:30. Do not use a
plus (+) sign if the GMT offset is positive.
X%
= On/off status
0 = off/disable
1 = on/enable
X*
= Volume level (0 – 100 steps). The maximum
volume level is limited by the max.
volume range command (
X?
*47#).
Default volume = 25.
X1!
= Version (typically listed to two decimal
places, e.g., x.xx)
N
With Telnet you can use either an “Escape” (
E
) command or a “W”
command, and the carriage return or the pipe character. With the Web browser,
you are required to use a “W” command and the pipe character.
In either method, {Data} = data that will be directed to a specifi ed port
and must be hex encoded if non-alphanumeric.
N
If you make adjustments (changes to volume, etc.), whether via the front panel
or via RS-232 or IP communication, it will take 1 minute 40 seconds (100
seconds) for the data in the MLC 226 IP’s RAM to be saved to fl ash memory.
