TS-3200 User's Manual
Technologic Systems
15.2 Using other debuggers
For example, the Turbo C debugger can be used on the target board using the TS-9500 video
and keyboard interfaces. Any other standard PC software debugger of your choice should
work just as well.
16 Video, Keyboard, and Console Redirection
The TS-3200 has no video controller or keyboard interface. This was done to keep the board size small
and the cost low. For applications that require it, a PC/104 video board can be added to the system
easily. Technologic Systems recommends the TS-9500, a PC/104 daughter board with video,
keyboard, mouse, and compact flash. This is extremely useful in speeding up the development phase
and shortening the time to market. With the TS-9500 installed, developers can develop right on the
target board with any compiler or debugger of their choice (such as the Turbo C compiler or debugger).
Without a video board in the system, the TS-3200 can redirect all console activity to the COM2 serial
port. Simply connect an ANSI terminal (or emulator) to COM2 with a null modem cable, using serial
parameters of 9600 baud, 8 data bits, no parity, 1 stop bit, and make sure jumper JP2 is installed. All
text information that would normally be displayed on a video screen is now displayed in your terminal
window, and any serial data sent to the TS-3200 is seen as standard keyboard input by programs.
Please note that the console redirection support is limited by the fact that there is no actual video or
keyboard hardware on the TS-3200. Programs must use the standard BIOS routines for display and
keyboard input, which are rerouted to the serial port. Any program that accesses the video or keyboard
hardware directly will not work. Keyboard redirection is limited simply because most of the extended
keys on the keyboard (function keys and Alt key in particular) are not sent by the terminal emulator. For
these reasons, the console redirection feature is meant more for system development, testing, and
field repair, rather than as the primary user interface for a finished product.
If your application uses COM2, removing the jumper JP2 easily disables console redirection.
If you wish to use a different serial port and / or baud rate for the console, the
utility
CONSOLE.EXE
allows these modifications to be made. Please see the appropriate application notes for further details,
available on the utility disk or from the Technologic Systems web site.
If a video board is installed on the PC/104 bus, the video BIOS on the graphics card will automatically
replace the standard video routines (INT10h), disabling both the LCD display and the console
redirection to COM2, regardless of the state of jumper JP2. If a video board is present, all console
input is disabled and the TS-3200 will only accept input from a standard PC keyboard.
17 Feedback and Updates to the Manual
To help our customers make the most of our products, we are continually making additional and
updated resources available on the Technologic Systems web site (www.embeddedx86.com). These
include manuals, application notes, programming examples, and updated software and firmware.
Check in periodically to see what's new!
When we are prioritizing work on these updated resources, feedback from customers (and prospective
customers) is the number one influence. If you have questions, comments, or concerns about your TS-
3200 Embedded PC, please let us know. Details for contacting us are listed in the front of this manual.
