PC Menu Interface Operation
XL™ Series
PC Menu Interface Operation 4-1
4.1 PC Menu Interface
All remote communications with the XL™ are through a command interface or menu interface
using the first RS-232 Serial Port. Note: A NULL modem connector must be used between the
PC and the XL™ for direct connections. If in the command mode, the command “MENU” is
used to start up the menu interface allowing simple human access to the system options. To
access the command or menu interface, the XL™ must be connected to a computer that is
running some type of terminal emulation program. The terminal emulation program must use the
same communication settings as used by the XL™. The default XL™ communication settings
are shown below along with other valid options.

Command Mode, Menu Mode
Basically all options available through the menu interface are also available using the command
interface or the built in keyboard and display. This chapter focuses only on the remote menu
interface.
When the computer is connected (direct connection or modem connection), pressing any key will
wake up the XL. If the XL is set to startup in menu mode then the main menu will be displayed.
If the startup mode is set to command mode, then pressing the ENTER key a few times will
cause the command interface prompt to be displayed. This prompt appears as an arrow “->” on
the left side of the screen. It may take a few key presses to “wake up” the XL™ and display this
prompt. Once the prompt is displayed, the XL™ is ready to receive commands. If no commands
are received in a five minute time period, the XL™ will turn off automatically and return to a low
power mode. Enter the command “MENU” at the prompt to access the menu interface.
