14  Loading or Transferring Files 

Two methods are available for transferring files between a desktop PC and your TS-5400: Compact 
Flash and Zmodem downloads. Full descriptions of each are detailed below. Other programs that use 
serial ports to transfer should work as well (for example, FastLynx). 

14.1  Developing with the Technologic Systems TS-9500 

The TS-9500 daughter board provides full VGA video, keyboard, and mouse interfaces necessary to 
work within most environments.  It also has a Compact Flash card that can be used even if the TS-5400 
is using a Compact Flash card as well. You can transfer your development tools (e.g. Turbo C) onto the 
TS-9500 Compact Flash card. Now you can compile, debug, and execute right on the TS-5400 target.     

14.2  Transferring files with Compact Flash 

The TS-5400 removable Compact Flash card can be used to easily move files from a host system.  We 
suggest using a low-cost SanDisk 



 USB compact flash card interface for your host system.  This is 

included in the TS-5400 Developer’s Kit. 

For best results, we have noticed that it is best to boot the host PC with a Compact Flash card installed 
in the SanDisk USB Reader.  The Compact Flash card can then be hot swapped (inserted or removed 
without rebooting the host PC). 

There are two other options for connecting a Compact Flash to your host computer. A Compact Flash 
to PCMCIA adapter, which can map a Compact Flash as a hard drive on your laptop host computer. Or, 
a Compact Flash to IDE adapter, which connects to the 40 pin IDE interface on you host computer.  The 
IDE adapter will allow you can boot to CF, run fdisk,  format, etc. 

14.3  Zmodem Downloads 

Using the Zmodem protocol to send files to and from the TS-5400 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-5400 from your host PC, execute 

DL.BAT

 at the DOS command line on 

the TS-5400 (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-5400 to your host PC, execute 

UL.BAT <FILENAME>

 at the DOS 

command line on the TS-5400 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 solid-state disk 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. To increase the download speed you could also use a ram disk on the TS-5400 to 
receive the download file, and then copy to the flash drive.  

To declare a ram disk insert this line into the config.sys file: device=\dos\vdisk.sys /kbtouse=1024 

Please note that the utility used to perform Zmodem file transfers on the TS-5400 side is called DSZ, 
produced by Omen Technologies. 

DSZ is shareware -- it is not free

. If you decide to use it, you are 

legally obligated to pay Omen Technologies. Currently the cost is $20. Further info is available in the 
DSZ zip file located on the utility disk, and contact info for Omen Technologies is in Appendix G.
