This document describes how a RI8574A Cassini16 EPC System Controller is upgraded to use an embedded Guru ID stored in the Tester's RIFL Master Hub instead of relying on a USB drive update method. It also includes Database 'Product Docs', View 'All Documents', Document 'Exchange Overview for System Controller EPC TIM'EPC Exchange Procedure and Database 'Product Docs', View 'All Documents', Document 'Exchange System Controller EPC TIM Checklist'Checklist. This update was generally available after July 2015.



Upgrade Procedure
Support for this feature is automatically enabled the first time Guru v72 is run with a Short Cut with Patch 241. Once the main Cassini window is done loading, the Guru ID will be saved to the RIFL Root Hub in the Testhead if a Guru ID is not yet present. If the Root Hub is replaced, type "RiEquipmentPool changeTesterSn" into the white area below the System button on the main Cassini window, select the text, right mouse click on it and choose DoIt or ShowIt to update the Root Hub's Guru ID with the currently running Guru ID.

Software Requirements
Guru v72+ (appears in Window List)
Patch 241 ( Options > Show Patches)

Hardware Requirements
RI8568B Cassini 16 Infrastructure
RI8574A EPC Controller for Cassini16


EPC Exchange Procedure:
1. After attaching a replacement EPC TIM, launch any ShortCut that meet the valid software requirements. Once the Tester begins loading, a dialog box will appear that says "Serial Number mismatch with EPC...", press OK to continue.

2. Open the Configuration window, choose System > Tester.
3. Choose Tester menu > Change EPC SerialNumber. Confirm the prompt.
This will copy the Guru ID from the RIFL Root Hub into the local guru (D:/guru/systemID) and migrate the RIFL Master offset value stored in C:\

4. Close Cassini app, Shutdown Guru with System > Shutdown.
Once Guru Restarts, launch Cassini and release to production.


When a EPC is exchanged, launch Short Cut or Custom App and open the Configuration window, choose System > Tester to open the Configuration window, then choose Tester > Change EPC SerialNumber. Confirm the prompt. This will copy the Guru ID from the RIFL Root Hub into the local guru (D:/guru/systemID). Close Cassini, Shutdown Guru. Once Guru Restarts, Login and confirm the Guru ID matches the system's Serial Number (label), then launch Cassini (Short Cut or Custom App) and release to production.
