4 - 8 MC3000 Integrator Guide SD Card (Windows CE 5.0 Only) Use the SD card to download/upload files to and from the mobile computer. See Secure Device Card (Windows CE 5.0 Only) on page 2-23 for more information. Creating and Loading Hex Images Terminal Configuration Manager (TCM) is an application used to customize flash file system partitions for the mobile computer. The most common use is to create an application partition hex file that contains the customer's application. TCM can also be used to load hex files to the flash memory of the mobile computer. The program resident on the mobile computer that receives the hex file and burns it to the flash memory is called Initial Program Loader (IPL). The customization of partitions is controlled by TCM scripts. The scripts contain all of the necessary information for building an image. The script is a list of copy commands specifying the files to copy from the development computer to the partition. TCM works with a pair of directory windows, one displaying the script and the other displaying the source files resident on the development computer. Using standard windows drag and drop operations, files can be added and deleted from the script window. The DCP includes scripts used by Motorola to build the standard factory installed Platform and Application partitions provided on the mobile computer. The standard Platform partition contains drivers while the Application partition contains demo applications and optional components. The standard TCM scripts can be found in the following folder: C:\Program Files\Symbol Windows CE SMDK (MC3000)\SymbolPlatforms \MC3000\TCMScripts. NOTE Before creating a script to build a hex image, identify the files required (system files, drivers, applications, etc.) and locate the files' source directories to make the script building process easier. The required processes for building a hex image in TCM include: • Starting TCM • Defining script properties • Creating the script for the hex image • Building the image • Sending the hex image to the mobile computer. NOTE Screens displayed in this section are sample screens. The actual mobile computer screens may vary slightly. Starting Terminal Configuration Manager Click the Start > Programs > Symbol > Symbol Device Configuration Packages > MC3000 C42V1.0 to start TCM. The TCM window appears displaying two child windows: Script1 and File Explorer. The Script1 window contains a newly created script and the File Explorer window contains a file explorer view used for selecting files to be placed in the script.
