The following steps make it easy to connect your programmer to the SigmaStudio development tool,
and then your programmer to your KABD amplifier. The steps require a basic knowledge of computer
operation, but if the steps are followed closely, it is not too complicated. Please
complete these steps in
this order
for consistent connection. Refer to the graphic above
Note:
Sigma Studio connection
requires a Windows PC and an ICP1 or KPX programming board.
1.
Download and install the most recent version of SigmaStudio to your system for free.
2.
Make sure your ICP1 or KPX is disconnected from USB and from your KABD amplifier before
starting, to ensure the proper steps are taken.
3.
Open an example project from downloadable from the Parts Express product page for the KABD-
250 or KABD-230.
4.
If starting a project from scratch (not recommended), open a new project in SigmaStudio by
pressing File->New Project. We recommend using an example project and modifying it for your
needs at least for the first time you re-program a KABD amplifier to make sure everything is
working correctly.
5.
Ensure that your ICP1 or KPX is
not
yet connected to the KABD. Set the switches on your ICP1 or
KPX appropriately for programming the KABD.
a.
KPX
–
Set the switches on your KPX
are set to “USBi” and “IIC” for proper programming
with the KABD.
b.
ICP1
–
Set the only
switch on your ICP1 to “PROGRAM” mode
6.
Plug an appropriate USB cable into your programmer (micro USB cable for ICP1, USB C cable for
KPX) into the PC running SigmaStudio, and then connect that USB cable to your programmer. Do
not connect the 6-pin cable into your programmer until after you have connected the USB cable.
7.
If all is correct, you will see the USB block turn green, like below.
a.
Note that this block turning green means that SigmaStudio recognizes your
programmer,
it does not indicate that SigmaStudio can communicate with your KABD
amplifier yet.
b.
If the connection is not successful (the block stays orange),
i.
Disconnect all cables from the KPX / ICP1 (6-pin cable, 4-pin cable), and then
plug in the USB cable to the KPX / ICP1.
ii.
it is important to try a different USB cable, even if
it’s a “good cable”.
Many USB
cables endure a lot of abuse from charging devices, and although they might still
provide power, they might have issues transferring data. Some micro USB cables
might not have been wired internally to transfer data at all, and only have
power wires internally.
