Configuring the Terminal
Introduction
This chapter describes the Terminal Configuration Manager (TCM), and how it is used to
specify and load files into the flash memory of the PDT 7200 using the terminal’s Initial
Program Loader (IPL).
TCM creates a table which lists the type of information, or “partitions”, to download to the
terminal. Partitions may be updated as new files or software upgrades are available. Use
caution updating mandatory partitions, as updating these improperly may cause the terminal
to function incorrectly.
Flash Partitions
In addition to the RAM-based storage standard on Windows
®
CE terminals, the PDT 7200
is also equipped with a non-volatile Flash-based storage area which can store data (partitions)
that can not be corrupted by a cold boot. This Flash area is divided into two categories: Flash
File System (FFS) Partitions and Non-FFS Partitions.
FFS Partitions
The PDT 7200 terminal includes up to three FFS partitions. These partitions appear to the
terminal as a hard drive that the OS file system can write files to and read files from. Data is
retained even if power is removed.
The three FFS Partitions are as follows:
!
The Platform FFS Partition contains system and Symbol-supplied programs and
Dynamic Link Libraries (DLLs). This FFS is configured to include DLLs that control
system operation. Since these drivers are required for basic terminal operation, only
experienced users should modify the content of this partition.
!
The Application FFS Partition is used to store application programs needed to
operate the terminal. This partition includes the Symbol demo program, which can
be overwritten with your own program.
!
The Data FFS Partition is available for user data files generated by your custom
programs.
