Commands and Reponses

Using the command/response table

The IPI 201/204 Series intercom can be controlled via either a Telnet (port 23) or RS‑232 connection using ASCII commands. Or it can be controlled via a Web browser (port 80) connection using URL-encoded commands. The ASCII and URL commands listed in the table starting on page B‑8 perform the same functions, but they are encoded differently to accommodate the requirements of each port (Telnet or browser).

The ASCII to hexadecimal (HEX) conversion table shown below is for use with the command/response tables.

The command/response table lists valid ASCII (for Telnet or RS‑232) command codes, the corresponding URL (uniform resource locator) encoded (for Web browsers) command codes, the IPI’s responses to the host, and a description of the command’s function or the results of executing the command.

•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, 11S0X4Q).

•Numbers can be entered with leading zeroes, as 1, 2, or 3 digits.

•There are a few differences in how to enter the commands depending on whether you are using Telnet or a Web browser.

ooWhen using these commands through a Web browser, the URL reference is used to shorten the examples. “URL” refers to the full URL of the intercom and Web page reference including all path information (e.g., http://192.168.100.10/myform.htm).

ooTo send any of the commands using a Web browser you must prefix them with the full URL followed by ?cmd=.
