Problems and Solutions
The status indicators fail to light when the software is started, or the
front-end commands and so on do not appear where they should
The I 2 C cable or the BNC-to-BNC cable from the front-end to the
PowerLab is not connected, has been connected incorrectly (to the
wrong input or output, for instance), or is loose.
• Turn everything off. Check to see that all cables are firmly seated
and screwed in. BNC cables from the GP Amp must be connected
to a positive input on the PowerLab. Make sure the input is the
same channel from which you expect to use the front-end in the
software. Start up again to see if this has fixed the problem.
You are using an early version of LabChart or Scope.
• Upgrade to the latest version of the software. Contact your
ADInstruments representative for information.
The BNC or I 2 C cable is faulty.
• Replace the cable and try again. Immediately label all cables
proved faulty so that you don’t use them again by accident.
The front-end is faulty.
• This is the least likely event. If the front-end will not work
properly after the previous measures, then try using it on another
PowerLab. If the same problems recur with a second PowerLab,
the front-end may be faulty. Contact your ADInstruments
representative to arrange for repairs.
On starting up the software, an alert indicates that there is a problem
with the front-end or driver
The correct Bridge driver is not installed on your computer.
• Reinstall the software.
