main software version, and a DSP software version. They may not be the same, but the more recent of these dates
should match the datecode of the update file just downloaded. If the updated versions do not appear, the
download failed and the old software is still installed.
TROUBLESHOOTING:
If serial communication cannot be established, the update program will respond: "Unable to determine baud rate", or
“No response on COM1”. If this happens, check the following items:
1. Make sure you are connected to COM1.
2. Make sure you are using a 9-pin straight-through type serial cable.
3. Try setting the 4530 to download at a slower baud rate. The update program will automatically detect the 4530
baud rate if it is set to 9600, 19200 or 38400 baud, so there is no need to change settings on the computer.
When the downloader is invoked, the 4530's initial serial port settings are always:
Baud rate: 38400
Data bits: 8
Stop bits: 1
Parity bit: none
Handshake: none
Check to make certain that these settings are correct. If you wish to try a slower baud rate, try selecting Serial >
BaudRate > 19200 from the downloader menu.
4. If COM1 is not available on your computer (perhaps it is in use by another device or program), you may force the
install program to use COM2 by executing it with “-2” in the command line. To do this, you must either execute
from a command prompt or from the Windows Start Menu, and specify the “-2” command line argument. Note that
the file must be saved to a disk first. This action cannot be performed from a browser or email client.
a) FROM A COMMAND PROMPT (“MS-DOS”) WINDOW:
Open a command prompt window, and type the full pathname of the install file, followed by a space and “ -2”.
Alternatively, CD to the directory containing the install file, and just type the filename followed by “ -2”. The
following example assumes the install file is in a directory called “download” under the root directory.
CD c:\download <enter>
UPD4530_020501 -2 <enter>
b) FROM WINDOWS START MENU:
Click on the Windows “Start” button, and select “Run”. When the dialog appears, click “Browse”, and locate
the install file. Select (highlight) the file, then click “OK”, and the full pathname of the install file should appear
in the “Open” box of the Run window. Next, place the mouse cursor at the end of the filename, and add “ -2”
(don’t forget the space), then click “OK” to execute the program.
5. Note that versions of the installation program prior to firmware version 20020501 accessed the serial port hardware
directly, and some newer Microsoft operating systems may impose limitations on this type of operation which
slow or totally prevent serial communications from taking place. It is recommended that MS-DOS, Windows 3.x, or
Windows 95 be used when loading these firmware versions. Version 20020501 (filename UPD4530_020501.EXE)
and later use standard, 32-bit, Windows calls for widest compatibility, but will not operate under MS-DOS or
Windows 3.x operating systems. Should you require a firmware loader that runs under MS-DOS or Windows 3.x,
please contact the factory.
