2-14 Installing the Detector
Making Ethernet connections
The detector rear panel also includes one Ethernet interface connector for
digital signal communications. Use this connector for devices such as these:
• Network adapter card in the Empower workstation
• Solvent manager
• MassLynx version 4.1 or higher
The Ethernet connector mates with standard Ethernet cable.
Making Ethernet connections with Waters data systems
When controlling the detector from a Waters data system or controller
(Empower or MassLynx workstation), you can use the Ethernet interface to
send and receive information from the data system.
When connecting via the Ethernet to these Waters data systems, you should
be aware of the following:
• When in dual wavelength mode, you must select a data rate of 1 point
per second in the data system method editor. In Empower software, the
data rate parameters defaults to 1 point per second.
Analog 2
b 2-V full-scale analog output signal of channel B (scaled
to the current AUFS setting).
Switch 1 (2) Used to connect to a fraction collector. Can be
controlled by threshold and timed events.
Switch 2 (2)
a. Inject Start, Chart Mark, Auto Zero, and Lamp inputs are configurable from the detector first
Configuration screen by setting the appropriate parameter to High. See “Configuring event
inputs (contact closures)” on page 3-23 for more detail.
b. See the discussion of attenuation in the detector analog outputs in “Making electrical power
connections” on page 2-9 .
Caution:
To avoid possible damage to components, power-off all
instruments on the Ethernet connector before you connect an
Ethernet cable to an instrument.
