This appendix overviews a way you can
load an updated software program into the
ZM-30, as provided on the Palstar website.
BACKGROUND
Increasingly today, microcontrolled projects
have an ability to be “field updated” with
new capabilities and software updates made
available by the designer. So instead of
needing to send your instrument back for re-
programming to get these new features, you
can now simply download the program
update from the Palstar website and send it
to the ZM-30, and the instrument will
automatically update its internal memory
with the new program. What a great way to
keep your project completely up to date with
the latest features!
PC REQUIREMENTS
•
Computer (at least 33 MHz Intel 486)
•
Windows 95, 98, 2000, or XP.
(Windows Vista may work.)
•
RS-232 serial port. USB-to-Serial
converters are not supported as the
timing requirements for loading new
ZM-30 firmware demand a genuine RS-
232 serial port.
•
Terminal emulator program. You can
freely download TeraTerm at
http://hp.vector.co.jp/authors/VA002416
/teraterm.html . It’s easy to install the
program. We will assume this terminal
program is being used in the following
discussion on usage.
USAGE
1. Download the latest ZM-30 software
from the Palstar website located at
www.palstar.com/zm30 . Save the
S19 file to a known location on your
PC (like in your desktop folder.)
The S19 file is the file with the
“.s19” extension to its filename.
This is a text representation of the
binary image to be loaded onto the
ZM-30.
2. Connect your ZM-30 to the PC using
a standard, straight-through male-
female DB9-type serial cable. Do
not use a null modem cable that
swaps pins 2 and 3 from end-to-end.
3. Start up the TeraTerm program on
your PC. If not already set up,
configure the communications as
9600 8N1, no flow control (in the
Setup Serial Port menu).
Very important: You must have the
line delay set to at least
“40ms/line”.
Make sure that you have TeraTerm
configured to be using the active
serial port in your PC. Be certain that
no other program has control of the
serial port – e.g., if your Palm
HotSync program is running, as
evidenced by its icon in the system
tray in the lower right of the screen,
you must quit that program by right-
clicking the icon and select “exit”.)
4. Issue the Update Software
command on the ZM-30, located as
an option under the SETUP menu.
The program called “HCmon” will
display its sign-on message on the
PC screen.
5. Type
C
to clear out memory on the
ZM-30. See the C character echoed
to the screen and the HCmon>
prompt displayed again.
6. Type L to load new program. See
message “…waiting …”
7. Pull down
the File Send File
menu.
8. Navigate to where you saved the
*.s19 file.
