Software Version 3.5

Hi Murdoc

I try to find the software version 3.5 in the yahoo group. Registered but cannot find. Any hints?


Thanks in advice!
Markus


Hi there,

could anybody send me the newest version of Locky_z's software, please? And has anybody the newest driver for the USB Version? I would be very pleased if anybody could share it.
Thank you!
Matthias

Edit:
I found the yahoo group and registered there. There I could download the version 3.5 of his software.
Now just the newest driver is missing.
 
Does the Yahoo group still exist? When I call up the address
given in the readme file of my Locky-Z, I get "server not found".
Maybe they moved to groups.io like most everybody else.

I think, I've got V 3.5 of the software.
The .doc files are partly electronically unreadable and the
rest is not really understandable. I managed to produce
some Id over Vgs plots for some JFETs. BJTs did not work
for me at all. My locky-z is sitting on the shelf collecting dust.

I have used this curve tracer very happily on a Windows7 PC since the original launch of the group buy.

But now that the move to Windows10 is imposed for the workshop PC which I want to be online as well, as I feared, the USB-to-Serial driver doesn't work (regardless of the original driver provided on CD with the curve tracer). I keep an offline Windows7 installation as well (for many other obsolete test devices/interfaces), but it would be nicer if the Win10 PC would allow the curve tracer to be used.

Having installed a 64-bits Windows10 Pro, with all possible updates to date, the curve tracer will not be able the obtain 'parameter from device', with the following screen shots from Win10 device manager:

"This device is working properly" .... yeah, right.... not really thus :no:
In other Windows versions (7, 8) it might also state "error code 10"

So, hereby a simple fix for how to FIX the "Prolific USB-to-Serial" driver issue, for anyone else encountering this problem.

Main cause of this issue is because the curve tracer contains a counterfeit (i.e. clone) Prolific chip. To solve this intellectual infringement, the original Prolific companies modified their newest drivers to render the counterfeit adapters unusable. Unfortunately this decision also renders all earlier adapters inoperative.

The Prolific drivers that Microsoft supplies via Windows Update, Versions 3.4.67.325, 3.4.25.218, 2.1.51.238 and 3.4.62.293 - will not work with most adapters and therefore shows the above or generic "Code 10" error. Or you may get no error at all, but the curve tracer will still not work.

As Windows 8, 8.1 and Window 10 are set by default to automatically update your drivers without your permission (or notifying you of the update) no matter how many times you remove the driver files and reboot - the next time you insert the USB-To-Serial adapter, Windows installs the newest non-working version again.

After some searching da mighty web, the only driver that works with all the "Prolific" adapters is Version 3.3.2.102.

32-bit here
64-bit here

The installer program will remove all of the incompatible drivers — make a change so that Windows can never update the driver without your approval — and install the Version 3.3.2.102 compatible drivers. Disconnect any USB-to-Serial device prior to installation, and connect the (powered-up) curve tracer during the installation process only when prompted to do so.

After installing the driver patch, the device manager screen and driver properties should look like this.

And when running the curve tracer start-up procedure, the very wanted screen:

Happy days again :spin:

I run it on Win7, on a virtual machine provided by VMware player on Linux Mint.

If Prolific had the slightest interest in selling their chips, they would probably
have a distributor one could find in 10 minutes.

If I could get hold of one good chip, I would probably buy it and replace the
pirate chip. This is DIY, after all.

And then I'll never buy anything with Prolific inside.
