This package is designed to let you change the Product ID code.

NOTES:
1) This utility only supports Windows

2) This utility is only supported for the 8.x (WinUSB) and 9.x (CyUSB) series drivers.  The 7.x series driver is deprecated.

INSTRUCTIONS
1) unzip all the contents of the .zip file onto your desktop, or other known location.  Do not run the executable from within the .zip as it will be unable to find the .INI file.

2) Run KeyMaster.exe

You should see two entries in the "right" panel and one entry in the "left" panel

*** If there is no entry in the "left" panel please follow the instructions in the "ACCESDebug.Readme.Txt" file, then re-run KeyMaster

6) Select the "left" panel entry you want to update (there's probably only one and it probably says "Old ID")
7) Select the "right" panel entry "[000C] USB-DIO-16H"
8) Click the "Set ID" button, located below the "right" panel.

9) Close KeyMaster.exe (click the "X" button in the top-right)
10) unplug your device (power it down if externally powered)
11) plug your device in.

Depending on your operating system you may need to re-run the New Hardware Found dialog, or go to Device Manager and "Update Driver".  We always recommend using the latest drivers from our website.

Please note: This process can only succeed if the device has a functioning EEPROM.
