Making signal connections 2-21
Single Waters instrument connection
Multiple Waters instrument connections
In a system configuration with many Waters Ethernet instruments, an
Ethernet switch is required to multiplex the communication between Waters
instruments and the acquisition computer.
Connection hardware requires one standard 100-base-T Ethernet cable per
Waters instrument, and a standard 100-base-T Ethernet cable to connect
between the network switch and the acquisition computer. Refer to the figure
“Multiple Waters ethernet instrument connections” on page 2-22.
You must install the Waters instrument control software in the acquisition
computer before the computer can control the Waters instrument. See the
software installation instructions that accompany the software instrument
driver disk.
Network installation guidelines
Configurations for multiple Waters instruments use a LAN (see the following
figure). This dedicated LAN requires a design based on the following
guidelines:
• 100-base-T, 100-Mbps shielded twisted-pair (STP) cable
• A maximum distance of 100 meters (328 feet)
Tip: You must use a network switch if you are using multiple Ethernet
instruments. Use of a network hub in place of a network switch is not
supported.
