What is the difference between a LAC/E32 and an acquisition client in Empower? - WKB71732

ENVIRONMENT

• Empower
• LAC/E
• Client

ANSWER

The terms are almost interchangeable.  

A client is generally something you sit in front of. There are Citrix clients and FAT clients. In this case, FAT means there is an Empower client installed on the machine, while the Citrix client has just the Citrix software loaded and displays the output of the session from the Citrix server.  

An acquisition client is a FAT client where there is instrumentation directly attached. This is done in cases such as the older MS systems where the drivers for the MS and the Watersservice are not compatible with each other.

An acquisition server has the Empower client loaded, instrumentation directly attached, and usually no physical monitor, mouse, or keyboard. Waters has a trademark on LAC/E32 (as a type of acquisition server). The benefit of the Waters LAC/E32 compared with a customer acquisition server is a standardized and tested image and hardware. 

The key differences:

LAC/E32s and acquisition servers have the Watersservice running and the ability for an administrator to reboot them from Configuration Manager. The Watersservice allows them be rebooted and to control attached instrumentation.

Acquisition clients have instrumentation attached. For Mass Specs running on Empower, the Watersservice is disabled by the MS driver installer, which then prevents the remote control of instrumentation.

Clients do not need the Watersservice running because there is no instrumentation attached.

Running the Watersservice on the Citrix server can cause processing jobs to queue up.
