SIS ™ Programming and Control, cont’d
IPL 250 • SIS Programming and Control 4-4
The command/response tables list valid ASCII command codes, the corresponding
URL (uniform resource locator) encoded (for Web browsers) command codes, the
IPL’s responses to the host, and a description of the command’s function or the
results of executing the command.
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, 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 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 will be misinterpreted by the IPL. 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]
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 specified port
and must be hex encoded if non-alphanumeric.
N If you make adjustments, it will take up to 1 minute 40 seconds (100 seconds)
for the data in the
IPL’s RAM to be saved to flash memory. Do not remove
power during that period.
