Entering SIS Commands: Helpful Tips
•
Upper and lower case characters may be used interchangeably in the command field
unless otherwise specified.
•
Commands may be sent back-to-back without spaces (for example,
2!65V1Z
).
•
Numbers can be entered as 1, 2, or 3 digits. For example:
8V
=
08V
=
008V.
•
There are a few differences in how to enter the commands depending on whether you
are using Telnet or a web browser.
•
When using these commands through a web browser, the URL reference
is used to shorten the examples. “URL” refers to the full URL of the control
interface and web page reference including all path information (such as
http://192.168.100.10/myform.htm
).
•
To send any of the commands using a web browser you must prefix them with the
full URL followed by
?cmd=
.
•
For control via a web browser, all non-alphanumeric characters must be
represented as the hexadecimal equivalent,
%
xx
, where
xx
represents the
two-character hex byte. A comma (,), for example, would be represented as
%2C
.
Characters such as %, +, and the space character ( ) must be encoded as hex
bytes, or they are misinterpreted by the MLC. For example, the ASCII command
+V
must be encoded as
%2BV
for web browser use.

Some characters differ depending on the method you use to send the commands:
Telnet
Web browser
Escape (hex 1B)
W [must not be hex encoded]
Carriage return (hex 0D)
Pipe character (
|
) [must not be hex encoded]
NOTE:
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 is be directed to a specified port and
must
be
hex encoded if non-alphanumeric.
NOTE:
If you make adjustments (such as changes to volume), whether via the
front panel or via RS-232 or IP communication, it takes up to 1 minute 40
seconds (100 seconds) for the data in the RAM of the MLC to be saved to
flash memory. Do not remove power during that period.
