Assembling the system 2-17
2. Connect the other end of the cable, using a stackable connector for
interconnecting additional instruments, to the IEEE-488 connector on
the controller’s rear panel.
3. If you are using the controller as part of a networked multi-system,
connect a second IEEE-488 cable to the stackable connector on the
controller. Connect the other end of the cable to the IEEE-488 port on
the next system component.
4. Repeat steps 2 and 3 for each additional component.
Tip: The maximum total cable length between all IEEE-488 devices is 65
feet (20 meters). The maximum recommended cable length between any
two IEEE-488 devices is 13 feet (4 meters). Longer total cable lengths
can cause intermittent IEEE-488 communication failures.
5. Ensure all IEEE-488 cable screws are fastened to finger tightness.
6. Specify a unique IEEE-488 address, from 2 to 29, for each device
connected on the IEEE-488 bus (see “Setting IEEE-488 addresses” on
page 2-18).
Perform the correct IEEE-488 startup sequence for the data system.
IEEE-488 cables with external PowerLine devices
When controlling external PowerLine devices from the Prep system, use the
IEEE-488 interface to communicate with the PowerLine devices (where the
PowerLine controller is the controller on the IEEE-488 interface). Set up the
PrepLC as a PowerLine controller.
To ready the PrepLC controller as a PowerLine controller, see the Waters Prep
Series Operator’s Guide.
Supported PowerLine devices include the following:
• Waters autosamplers (for example, 717plus)
• Waters detectors (for example, 2487 and 2414)
To make IEEE-488 connections with external PowerLine devices
1. Connect the single-receptacle end of the IEEE-488 cable (supplied with
either the Prep system or the data system) to the IEEE-488 connector on
the controller’s rear panel.
