Program Upgrades
The Zapco Digital Programming Network is an evolving entity. As it evolves we can issue program
updates. If there are firmware upgrades we will issue a Install application which you can place on your
desktop.
Before doing the update, make a note of the COM port the DSP is using. You will find the COM port
at the bottom of the GUI screen on the right side.
Close the DPN GUI, but keep the DSP turned on and connected to the PC.
The two-step upgrade process is straightforward as below.
A) Update the PC Program:
1) Put the new version
Zapco DPN (V -.-.-.-) Install
application file on your desktop
but do
not open yet.
2) In PC’s
Control Panel
>
Remove Program
> Locate the old Zapco DPN at the bottom of
the list and click and
Uninstall.
3)
Now, return to desktop and click on the new Zapco DPN Install file and follow the
directions to install the new program version. (Wait at the end for DOS to finish installing
the drivers)
B) Update the DSP with a new .Hex file to match the PC program update:
1) Open Zapco Updater
2) Click Open File and navigate to the new
.
hex
file. Open the .hex file and it will appear in the
Updater screen.
3) Next, verify that the COM Port number is correct. If it is not then pick the correct one from
the drop-down list. Click “Open COM”. The Com Port will turn blue and “Start Update” light
will glow blue. You are ready to update.
4) Turn the stereo off and then back on. When the DSP cycles off and back on the Update will
start.
You will see the update progress in the top LED Bar and also in the bottom “
message
”. When the
message
says it is finished you can click “Close COM” and then close the update screen.
