GETTING STARTED

Transferring Files via Flash Memory Device

An SD card or an USB flash memory card can be used to easily move files from a host
system. We suggest using a low-cost SanDisk USB Compact Flash card or SD card
interface for your host system. USB memory devices need no extra accessory to connect
to the host PC. The flash memory devices can then be hot swapped (inserted or removed
without rebooting the host PC).

Zmodem Downloads

Using the Zmodem protocol to send files to and from the TS-7400 SBC is simple and
straightforward. The only requirement is a terminal emulation program that supports
Zmodem, and virtually all do. If you are using Windows 95 or later for your development
work, the HyperTerminal accessory works well.
To download a file to the TS-7400 from your host PC, execute lrz at the Linux command
line on the TS-7400 (while using console-redirection from within your terminal emulator)
and begin the transfer with your terminal emulator. In HyperTerminal, this is 'Send File...'
from the 'Transfer' menu.
To upload a file from the TS-7400 to your host PC, execute lsz <FILENAME> at the Linux
command line on the TS-7400 and start the transfer in your terminal emulator. Many
emulators, HyperTerminal among them, will automatically begin the transfer themselves.
Occasionally there may be errors in transmission due to background operations. This is
not a problem -- Zmodem uses very accurate CRC checks to detect errors and simply
resends bad data. Once the file transfer is complete the file is completely error free. For
best results when using HyperTerminal, the hardware handshaking must be enabled in
HyperTerminal.

2.5 TS-7400 production lifetime

The TS-7400, as shipped by default from Technologic Systems will never be altered
significantly from its originally introduced state. The board has an intended infinite
production lifetime, meaning Technologic Systems will build and sell TS-7400's in as low
as single piece quantities as long as its constituent parts are readily available. This
typically means a production lifetime of 10-15 years. A stable hardware platform and
default install keeps unexpected surprises from cropping up down the road when products
must be retested or redesigned because of manufacturer introduced hardware/software
design changes or obsolescence.
The 802.11g card for the TS-7400 is not manufactured by Technologic Systems. 802.11
wireless ethernet is tightly coupled to the consumer electronics and desktop computer
industries and as such products tend to be more transient (though also less expensive).
Often times manufacturers change chipsets or discontinue products with little or no notice.
Although usually there are many alternatives and Technologic Systems can seamlessly
transition to a new supplier, TS-7400 integrators should be aware of the possibility of
different 802.11 type devices being used on the default product in the future.
