Data buffer overflow error on ACQUITY UPLC TUV/PDA in Console - WKB88452

SYMPTOMS

• Data buffer overflow error on TUV/PDA displayed in the instrument console.
• TUV was unable to change wavelength or view its system info without crashing the console.

ENVIRONMENT

• ACQUITY UPLC TUV
• ACQUITY UPLC PDA

CAUSE

Bad communications between the TUV/PDA and the PC. The Waters DHCP server only displayed a couple of the system modules and not all of their info.

FIX or WORKAROUND

1. Power-off modules
2. Run Stop ACQUITY Processes, restart the PC.
3. Remove all the present modules from the Waters DHCP server
4. Power-on the Ethernet hub containing the module first, usually the sample manager. Ensure that it correctly populates the Waters DHCP server, and then power-on the remaining modules.
5. If the Waters DHCP server contains all modules, then open the Console and confirm the performance
