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.

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.
