Before you can generate a chart-mark from the 2695 separations module, you need
to configure the chart-mark signal at the detector’s front panel. The default
chart-mark signal setting is Low (see the discussion “Configuring event inputs
(contact closures)” on page 64 for more information).

making a chart-mark on injection
2.6.7 Connecting the detector to a chromatography data
workstation using an e-SAT/IN module
Acquiring data and controlling the detector with Empower software or MassLynx
software, by using the e-SAT/IN™ module instead of the Ethernet bus, requires
connections between the following hardware:
• Ethernet card
• Ethernet satellite interface (e-SAT/IN) module
2.6.7.1 e-SAT/IN module
The Waters e-SAT/IN module shown in the figure below translates analog signals from
devices such as the detector into digital form. It then transmits these digital signals
using an ethernet card installed in the chromatography data workstation.
Note:
The e-SAT/IN module does not have a power switch. Always disconnect the
power cord at either the wall outlet or the power supply before attaching or removing
the power connection to the e-SAT/IN module.
