Configuring the Terminal
Initial Program Loader (IPL)
Initial Program Loader (IPL) is a small utility program that is built into each terminal. The
purpose of IPL is to provide a simple method of updating the flash contents via the serial port
or cradle. The images that IPL can accept are in the form of “hex” files that contain not only
the data to be downloaded to the terminal, but also sufficient extra information to ensure that
each hex file contains an image for a single partition. Hex files for standard system
components such as the boot loader and Windows
®
CE Core are provided by Symbol. Hex
files for custom components, such as disk images or custom partition maps are built on a PC
using the TCM program. IPL is only capable of loading whole partitions (it cannot update
individual files in a disk image).
Using the Keyboard
Operation of the IPL is controlled by the touchscreen. IPL recognizes the following controls:
!
Cursor Up arrow
!
Cursor Down arrow
!
Enter or Trigger
!
Backlight icon
!
Contrast icon (lighter/darker).
The effects of these keys are as follows:
Cursor Up/Down Touching the screen on the up/down arrows causes the previous/next item in
the menu to be highlighted. Moving off the end of a menu causes a wrap to
the other end of the menu list. If the menu is longer than the screen is deep,
then screen will automatically scroll up or down to keep the highlighted item
visible on the screen.
Enter or Trigger
Touching the screen or pressing the trigger causes the currently highlighted
item to be selected, and IPL advances to the next screen.
Backlight
Pressing this icon toggles the backlight (if present) between on and off. This
icon is always active (even if IPL is not in a menu screen).
Lighter/Darker
Each press of this icon adjusts the screen contrast up. Holding this icon down
adjusts the screen contrast down. The keys are always active (even if IPL is
not in a menu screen).
