Connecting the NIBP Controller
Connecting to PowerLab
To connect the NIBP Controller to your PowerLab system, first make sure
that the PowerLab is turned off. Connect your PowerLab to the computer and
power, as detailed in your PowerLab Owner’s Guide. Note: the PowerLab
should remain off while making connections to it as hardware may be
damaged if the PowerLab is on.
Connect the I

C Output of the PowerLab to the I
2
C Input of the NIBP
Controller. Additional ADInstruments front-ends may be connected to the
system by connecting to the I
2
C Output of the NIBP Controller.
With BNC cables, connect the Pulse Signal Out socket on the back of the
NIBP Controller to one of the analog inputs on the front of the PowerLab and
connect the Pressure Signal Out socket on the back of the NIBP Controller to
another of the analog inputs of the PowerLab. Both these connections must be
made to determine blood pressure.
Optional Trigger Controls
The NIBP Controller has two control signal sockets on the rear panel. The
Trigger In is used to start an NIBP measurement cycle from an external
source such, as the PowerLab. By connecting this input to either the analog
output or digital output (if supported) of your PowerLab you can get the
LabChart or Scope software to automatically start the NIBP Controller at
preset times.
