RTI ProLink.z Firmware Version 20.8.25

VERIFYING THAT YOU NEED THE UPGRADE
If you already have version 20.8.25 or newer you should not upgrade your
firmware to this version. Use the "Get Firmware Version" command from
the Communications menu in Integration Designer to determine the current
firmware version. The reported version number will consist of a number
followed by a bootloader version number [for example: 20.8.25 (Bootloader: 1.3)]. 
If the first part of the reported version number is 20.8.25 or
higher, you do not need this update.

PREREQUISITES FOR USING THIS UPGRADE PROCEDURE
Integration Designer APEX 10.2 or higher must already be installed on the
PC that you wish to use to upgrade the ProLink.z firmware. Upgrading to the
latest version of Integration Designer APEX is strongly recommended.  You
should verify that you can communicate with the ProLink.z using Integration
Designer before attempting to upgrade the firmware.

FIRMWARE UPGRADE PROCEDURE
1. Connect power to the ProLink.z and make sure it operates normally.
2. Make sure Integration Designer APEX 10.2 or higher is installed on the
   PC that you are using to update the ProLink.z firmware, and that Integration
   Designer can communicate successfully with the ProLink.z.  You can use the
   "Get Firmware Version" command on the Communications menu in Integration
   Designer to verify that the USB communications are working properly.
3. Run the ProLinkZUpdate_20.8.25.exe program contained in this ZIP file and follow
   the on-screen instructions carefully.
