2. Connect the other end of the cable, using the stackable connector for
interconnecting additional instruments, to the IEEE-488 connector on
the next PowerLine instrument.
3. If using a multicomponent configuration, connect a second IEEE-488
cable to the stackable connector on the PowerLine instrument. Connect
the other end of the cable to the IEEE-488 port on the next PowerLine
component.
Setting IEEE-488 addresses
You must set a unique IEEE-488 address, between 2 and 29, for each device
on the IEEE-488 bus so that the device is recognized on the IEEE-488
interface. When setting the address, note these instructions:
• When using a data system (MassLynx or Empower workstation), set the
IEEE-488 address of the Gradient controller from the application's
Pump Configuration screen.
• When using the controller as a PowerLine controller, you do not set the
IEEE-488 address of the Prep system pump. In the PowerLine system
configuration, set the IEEE-488 address for each of the other PowerLine
instruments through the instrument software or DIP switches. A
previously set address has no effect in PowerLine configuration.
Recognizing IEEE-488 addresses
After you set the address for an IEEE-488 device, cycle the device off and then
on again. The new address is not recognized until the device undergoes its
calibration or diagnostic routines (performed at startup).
Startup sequence for IEEE-488 devices
This section describes the correct IEEE-488 startup sequence when you use
these devices:
• Prep system with a data system (PrepLC controller in Gradient mode)
• PrepLC controller as a PowerLine controller
Caution:
PowerLine controller recognizes other devices on the IEEE-488
interface.
2-18 Installing the System
Perform the following steps to ensure that the data system or
