Commands and Responses
Using the command/response tables
The MLC 226 IP can be controlled via either a Telnet (port 23) or RS-232 connection 
using ASCII commands. Or it can be controlled via a Web browser (port 80) 
connection using URL-encoded commands. The ASCII and URL commands listed 
in the tables starting on page 5-8 perform the same functions, but they are encoded 
differently to accommodate the requirements of each port (Telnet or browser).
The ASCII to hexadecimal 
(HEX) conversion table shown 
at right is for use with the 
command/response tables.
The command/response tables list valid ASCII (for Telnet or RS-232) command 
codes, the corresponding URL (uniform resource locator) encoded (for Web 
browsers) command codes, the MLC 226 IP’s responses to the host, and a 
description of the command’s function or the results of executing the command.
•  Upper and lower case characters may be used interchangeably in the command 
fi eld unless otherwise specifi ed.
•  Commands may be sent back-to-back without spaces (for example, 2!65V1Z).
•  Numbers can be entered as 1, 2, or 3 digits, e.g., 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 
(e.g., http://192.168.100.10/myform.htm).
•  To send any of the commands using a Web browser you must prefi x 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 will be 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]
