9. Once in the folder that contains
zm30v2-2.s19
file, select that file
and click the Open button.
Very Important: Be careful to only
load S19 files!
If you mistakenly
select any other file extension, it is
very likely that you'll mess up the
bootstrap loader program.)
10. See line after line of ASCII data
displayed in short one-second bursts.
This will continue for about 2
minutes until the entire program has
been sent to the ZM-30 and has been
flashed into its memory. DO NOT
INTERRUPT THIS PROCESS!!
When it is complete, the
HCmon >
command prompt will be displayed
again.
11. Type
X
to exit the HCmon program
and the ZM-30 will power down.
Disconnect the serial cable and
power the ZM-30 on again with the
On/Off pushbutton to start the
newly-loaded program. You will see
the new version number presented in
the LCD sign-on message.
12. Very Important: The first thing you
must do after loading new software
is to go into the SETUP menu and
select the Default Settings item.
This will synchronize the internal
nonvolatile EEPROM memory in
your ZM-30 with the new software
you just loaded. (If this step is
omitted, strange things are likely to
happen, like the beeper sounding
when it shouldn’t, or some unusual
impedance results being shown.)
13. Lastly, be sure to calibrate your
instrument after loading new
software. The ZM-30 retains the
calibration parameters in a special
nonvolatile section of EEPROM
memory that is not cleared when
Default Settings is invoked, but these
parameters also must be
synchronized with the newly-loaded
software and it’s good to ensure you
are calibrated with the software
currently loaded on your instrument.
IN CASE OF SOFTWARE LOADING
PROBLEMS
The normal indication of new software
being successfully sent to the ZM-30 is
seeing line-after-line of nicely-formatted
text data being displayed to the PC terminal
screen, as indicated in Step #10 above.
However if this process is interrupted for
some reason (such as your computer
accessing the Internet in the background, or
you task switching over to another
program), the PC data link to the ZM-30 can
get out of sync, resulting in either a
complete stopping of the scrolling data lines,
or unusual and unformatted data continually
being displayed to the screen. Neither of
these conditions will end in a successful
display of the HCmon prompt and the
software memory of the ZM-30 will be left
blank … brain dead.
But all is not lost! There is an alternate way
to load new software into your ZM-30.
ALTERNATE LOADING METHOD
1. Remove power from the ZM-30 by
pulling the power plug (if the unit is
externally powered), or by opening the
battery compartment and removing one
of the batteries (if the unit is battery
powered).
2. Open the ZM-30 case by removing the
four screws on the sides of the
instrument.
3. Locate the two 2-position pinheaders in
the lower left portion of the pc board –
one is just above the round piezo speaker
device, and the other is about 0.5” to the
right of the speaker.
4. Place the two supplied shunts (small
black jumpers) onto these two
pinheaders, ensuring that each of the two
pinheader pins is shorted by its
respective shunt.
