B-5 IPI 100 and IPI 200 Series • SIS Programming and Control
o 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 IPI.
o 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 (changes to volume, etc.), whether via the front panel or
via RS-232 or IP communication, it will take 1 minute 40 seconds (100 seconds)
for the data in the IPI 200 series’ RAM to be saved to flash memory.
Symbol definitions
] = CR/LF (carriage return/line feed) (hex 0D 0A)
} = Carriage return (no line feed, hex 0D)
(use the pipe character, | , instead for URL‑encoded commands)
• = Space character
| = Pipe (vertical bar) character
E = Escape key (hex 1B)
(use W instead of Esc for Web browsers)
N For Web encoding only: data will be directed to the specified port and
must be encoded (URL encoding) if it is non-alphanumeric. Change any
non-alphanumeric character (%, +,
| , } , etc.) within the data section into
the corresponding hexadecimal equivalent, %xx, where xx represents the
two-character hex byte. For example, a space (hex: 20) would be encoded as
%20 (hex: 25 32 30) and a plus sign (hex: 2B) would be encoded as %2B or
hex 25 32 42.
X# = Greenwich Mean Time (GMT) offset value (‑12.00 to +14.00) represents the
time difference in hours and minutes (+/‑hh:mm) relative to Greenwich,
England. The leading zero is optional. For example, 5:30 = 05:30. Do not use
a plus (+) sign if the GMT offset is positive.
X% = On/off status
0 = off / disable
1 = on /enable
X1! = Version (typically listed to two decimal places, e.g., x.xx)
X1@ = IPI 200 series’ name. The name is a text string of up to 24 characters drawn
from the alphabet (A‑Z), digits (0‑9), and minus sign/
hyphen (‑). No blank or space characters are permitted as part of a name.
No distinction is made between upper and lower case. The first character
must be a letter. The last character must not be a minus sign/hyphen.
