Using the Command and Response Table
The PCS4 can be controlled via either a Telnet connection (port 23) or a web browser
connection (port 80). The ASCII commands listed in the tables perform the same functions,
but they are encoded differently to meet the requirements of each port (Telnet or browser).
The ASCII to hexadecimal (HEX) conversion table below is for use with the command and
response tables.

The command and response table lists valid ASCII (for Telnet) command codes, the
corresponding URL (universal resource locator) encoded (for web browsers) command codes,
the interface responses to the host, and a description of the command function or the
results of executing the command.

There are a few differences in how to enter the commands, depending on whether you
are using Telnet or a web browser.
When using these commands through a web browser, you can use the URL

reference to shorten the examples. "URL" refers to the full address of the
control interface and web page reference, including all path information (that is,

For control via a web browser, all non-alphanumeric characters must be represented

as the hexadecimal equivalent,

as %, +, and the space character must be encoded as hex bytes, or they will be
misinterpreted by the interface.
Some characters differ depending on the method you use to send the commands:

Escape (hex 1B)
Carriage return (hex 0D)
