Using the Command and Response Tables

These tables contain Telnet (port 23), serial, or web browser (port 80) commands. There are some minor differences between issuing these commands via Telnet and via URL encoding using a web browser. All commands work with either connection method but, due to some limitations of the web browser, the encapsulation characters are modified to make sure that the browser properly handles them.

NOTE: For web browsers, all non-alphanumeric characters must be represented as

their hexadecimal equivalent. An example is the %xx command, where xx is

the two-character representation of the hex byte that needs to be sent. (For example, a comma would be shown as %2C.)

Telnet	Web browser
Escape (Hex 1B)	W (must not be encoded)
Carriage Return (Hex 0D)	Pipe Character ( ) (must not be encoded)

When SIS commands are used through a web browser, the URL reference is used below to shorten the examples. In practice, this would be the full URL of the control interface and web page reference, including all path information; for example, http://192.168.254.254/ index.html

To send any of the commands using a web browser, prefix them with the full IP address, followed by ?cmd=.

NOTE: With Telnet you can use either the Escape commands or the W commands, and

the carriage return or the pipe ( ) character. With the web browser you are required to use the W commands and the pipe character.

In either method, {Data} is data that is directed to a specified port and must be encoded if it is non-alphanumeric.

The Command and Response Tables for SIS Commands, starting on page 55, list the commands that the DVS 510 scaler recognizes as valid, the responses that are returned to the host, a description of the command function or the results of executing the command, and command examples.

NOTE: If the unit does not support or recognize a command that is entered, no action is taken and no response is returned.
