Extron electronic IPI 200, IPI 100 manual Symbol definitions, Telnet, Web Browser

ooFor 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.

ooSome 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)

NWith 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.

NIf 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)

NFor 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! = X1@ =

Version (typically listed to two decimal places, e.g., x.xx)

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.
