The wafer reader supports many Native Mode commands that allow the wafer reader to
be controlled from users’ custom application programs over Ethernet or serial port.
The Native Mode protocol is divided into two sets of commands: Basic and Extended.
Basic Native Mode commands are two characters long, plus parameters (if any) and a
terminator character; Extended Native Mode commands include additional functions or
commands. The commands are not case sensitive. The terminator is CR + LF (ASCII
characters 13 + 10) when sending Native Mode commands using a Telnet connection.
The default terminator is CR (ASCII character 13) when using Native Mode commands
over a serial port.
When a Native Mode command is remotely issued to an In-Sight wafer reader, the
In-Sight wafer reader processes the command and then returns a response, consisting of
an ASCII string followed by the terminator character. Commands that set values return
1
for "success", 0 for "unrecognized command", or a negative number for "failure".
Commands that get values return various values, depending on the command.
NOTES
■ Changes made using Native Mode commands are not reflected in the browser interface.
■ When logging on to an In-Sight wafer reader through Telnet from a Unix-based platform, the
In-Sight wafer reader’s Host Name (or IP address) and port number (usually 23) must be added to
the command line. For example: >telnet is1721_00060b 23. Supplying the port number disables
the Unix username/password authentication and forces the Unix system to prompt you for user
name and password.
