Chapter 2— Configuring the Terminal
Trakker Antares 2475 Vehicle-Mount Terminal User’s Manual 35
Configuring Drives and Memory on the Terminal
The 2475 comes with a 750K flash drive (C) and 512K RAM reserved for
applications. You can also order a 2475 with an additional 2MB extended
flash memory option. You can customize the terminal by configuring:
• up to 256K of the 512K RAM as a RAM drive.
• the additional 2MB flash memory to either store double-byte fonts or to
use as a 2MB drive.
Configuring the RAM Drive
The 2475 has a total of 512K RAM for the application execution space.
You can configure up to 256K of the total 512K application execution
space as a RAM drive. If the RAM drive is configured, your application
execution space is reduced by the amount of the RAM drive.
For example, if your application size is 64K and drive E is configured as a
256K RAM drive, you are using 320K of the 512K application execution
space. The application uses the remaining 192K of RAM as a Malloc/free
dynamic memory pool.
By default, the RAM drive is not configured and the memory is available
for applications. You can configure the size of the RAM drive (E) and use
drive E to temporarily store data and files (up to 128 files).
After you disable or configure the RAM drive, you must save the
configuration in flash memory and boot the terminal for the change to
take effect. For help, see “Saving Configuration Changes in Flash
Memory” in Chapter 2 of the 2400 Family system manual.
Note: When you boot or reset the terminal, all files on the RAM drive are
destroyed.
For help configuring the RAM drive, see “RAM Drive Size” in Chapter 6
of the 2400 Family system manual.
Configuring Flash Memory
If you ordered the optional 4MB flash memory drive, you have an
additional 2MB of extended flash memory. You can use this flash memory
either to store double-byte fonts or to use as a 2MB drive. By default, the
additional 2MB of flash memory is configured to store a double-byte font
set (up to 2MB maximum).
Note: The 4MB flash memory is required for 802.1x TTLS security and is
not available to store files or double-byte fonts. For more information
about configuring 802.1x TTLS security, see “Configuring 802.1x TTLS
Security” on page 50.
