ASCII to HEX Conversion Table
ASCII to hexadecimal character conversion table
The command/response tables list valid ASCII (for Telnet) command codes, the
corresponding URL encoded (for Web browsers) command codes, the MGP’s
responses to the host, and a description of the command’s function or results from
executing the command.
Upper- and lowercase characters may be used interchangeably in the
command field unless otherwise specified.
Commands may be sent back-to-back without spaces; for example, 2*2!2*0B.
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.
For control via a Web browser, all nonalphanumeric characters must be
represented as the hexadecimal equivalent, %xx, where xx represents the
two-character hex byte. For example, a comma (,) would be represented as
%2C.
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; for
example, http://192.168.100.10/myform.htm.
Some characters differ depending on the method you use to send the
commands:
Telnet Web browser
Escape (hex 1B) W [must not be encoded]
Carriage return (hex 0D) Pipe character (
|
) [must not be encoded]
With Telnet you can use either the “Escape” commands or the “W”
commands, and either the carriage return or the pipe character. With the Web
browser, you are required to use the “W” commands and the pipe character.
In either method, the data string (shown in braces as {data} in the
Command/response table) is directed to the specified port, and must be
encoded if it is nonalphanumeric.
