Commands and Responses
Using the command/response tables
The MPX 423 A can be controlled via a Telnet connection (port 23) or a Web browser
connection (port 80). The ASCII and URL commands listed in the tables starting on
page 4-9 perform the same functions, but are encoded differently to accommodate
the requirements of each port (Telnet or Web browser).
This ASCII to hexadecimal (HEX) conversion table is for use with the command/
response tables.
ASCII to HEX Conversion Table

Figure 4-1 ASCII to Hex conversion table
The command/response tables list ASCII command codes (for Telnet or RS-232),
the corresponding URL encoded command codes (for Web browsers), the unit’s
responses, and a description of the command’s function or results.
The following rules apply for commands and responses:
• Upper and lower case characters may be used in the command field unless
otherwise specified.
• Commands may be sent back-to-back without spaces (for example, 2!65V1Z).
• Numbers can be entered in 1, 2, or 3 digits, e.g., 8V = 08V = 008V.
• Telnet control versus Web browser control differences include:
• For a Web browser, “URL” is used to shorten the examples. “URL” refers
to the full URL of the control interface and Web page, including all path
information (e.g.,
http://192.168.100.10/myform.htm
).
• To send a Web browser command, prefix it with the URL and
?cmd=
.
• For Web browser, all
non-alphanumeric characters
must be coded with
the hexadecimal equivalent,
%xx
, where
xx
is the two-character hex byte.
For example, a comma (
,
) is coded as
%2C
. Characters such as
%
,
+
, and
space ( )
must
be coded with hex bytes to be interpreted correctly.
• Some characters differ depending on the method used.
Telnet
Web browser
Escape = W
or
(hex 1B)
Escape = W [must
not
be hex encoded]
CR = Pipe (
|
)
or
(hex OD)
CR = Pipe (
|
) [must
not
be hex encoded]
In either method, {Data} = data that will be directed to a specified port
and
must
be hex encoded if non-alphanumeric.

If you make adjustments (changes to volume, etc.), via the front panel, RS-232
or IP, it takes 100 seconds for the new data to be saved to flash memory.
