Using the Command Line Interface

The default serial port settings for the test fixture are 9600, N, 8, 1, NONE, with local echo turned on
in the terminal emulator of choice. When power is applied to the test fixture, the following welcome
banner comes up in the terminal window.

If this banner is not displayed, then recheck the serial port connection and settings.

All serial port commands are case insensitive. While the help menu displays commands in upper
case, they may be entered in lower case. The PD command requires parameters to be entered in
hexadecimal format without any prefix or postfix characters (see the help menu for an example.) The
letters in the hexadecimal numbers may be lowercase as well.

A listing of all the supported commands with parameter limits is displayed by typing the command
HE as shown in the welcome banner. Following is an output example of the help menu.
