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.
