7 Installing the
Electronics Module
The ASXPRESS PLUS electronics module needs to be connected to the power
supply, to the ASX
PRESS PLUS valve/pump module, to the autosampler, and to the
host computer.
The electronics module needs two connections to the host computer:
GUI COM: This connection allows the Xpress Configuration Tool software to
configure timing and other parameters in the electronics module.
OEM COM: This connection intercepts commands as they are sent from the ICP
software on the host computer to the autosampler. Commands to inject a
sample cause a program (the “macro”) to run, which synchronizes the flow
from the autosampler with operation of the valve. Other commands are simply
passed on to the autosampler.
