Simple Control Port Commands - Telnet and Web-browser Accessible

Upper and lower case text can be used interchangeably except where noted. Port 23 is default for Telnet. Port 80 is default for web browsers. They both can be mapped to different ports.

The following commands are for either a Telnet (port 23) or web browser (port 80) connection. There are minor differences when implementing these commands via Telnet or via URL encoding using a web browser. All commands listed will work using either connection method but due to some limitations of the web browser, the encapsulation characters must be modified to be certain the web browser will properly handle them. All examples are shown in a proper implementation of a Telnet or web browser session.

NOTE: When using web browsers, some non-alpha numeric characters must be represented as their hex equivalent such as %xx where xx equal the two character representation of the hex byte that needs to be sent (a comma ‘,’ would be represented as %2C). Characters such as ‘%’ (percent), ’+’ (plus) and ‘ ‘ (space) should also be encoded in Hex.

Telnet

Web Browser

Escape (Hex 1B)

W [must not be encoded]

Carriage Return (Hex 0D)

Pipe Character () [must not be encoded]

When describing the use of SIS commands via a web browser, the (URL) reference is used to shorten the examples. (URL) would be the full URL of the control interface and web page reference including all path information (http://192.168.254.254/mypage.HTML).

To send commands using a Web browser, prefix them with the full URL followed by ?cmd= (http://192.168.254.254/mypage.html?cmd=WSF>).
