• The maximum range of the detector time constant setting depends on
the wavelength mode and data rate selected. See the
Table titled
“Primary and secondary function (method) parameters” on page 3-19 .
• Empower allows the detector to operate in both single and dual
wavelength modes with a wavelength range of 190 to 700 nm, and up to
4.0 AUFS.
To connect Ethernet cables from the detector to a Waters data system:
1. Connect the single receptacle end of the Ethernet cable to your data
system by attaching the cable to the network adapter (laboratory
acquisition and control environment, or LAC/E).
Note: The Ethernet cable is supplied with the Waters data system.
2. Connect the other end of the cable to the Ethernet connector on the
detector rear panel.

Tip: When connecting the detector to a data system, all detector parameters
not configurable by the data system in use defer to local control.
Caution: The maximum total cable length between Ethernet devices
in a system is 20 meters (65 feet). The maximum recommended cable
length between two Ethernet devices is 4 meters (13 feet). Longer
total cable lengths can cause intermittent Ethernet communication
failures.
