Update CAV 4.2 Software and Firmware
Software and firmware code updates may occasionally need to be manually installed on the CAV 4.2
user-interface, controller boards, and controlling PCs. There are four types of code that can be installed:
•
UI updater: this software is actually the complete UI updater program (UpdateUI.exe) that runs on
the CAV 4.2. It is used to install the UI software and firmware updates. It is updated by copying it
over the existing UpdateUI.exe.
•
CAV 4.2 GUI software: this software is the CAV 4.2 user-interface. To update the CAV 4.2 GUI
software, you must be logged out of the user-interface and running the UI updater instead.
•
Firmware updates: this code controls the baths, sample handlers, and valve controls. It is installed
directly onto the respective controller boards using the UI updater.
•
VISCPRO II: this software is installed on the controlling PC.
