Chapter 8 REMOTE OPERATION

8.1 Remote Operation

The LBA-PC has nearly full GPIB remote control capabilities and partial ActiveX remote control capabilities. During the installation phase you were asked if remote operation was required. If you answered yes to the query, the installation process will have loaded the appropriate device drivers that allow the LBA-PC to communicate with a National Instruments GPIB interface card. The ActiveX servers are always available.

If you installed the remote operation by mistake, see How to Disable Remote Operation in section 8.2.

Note: The LBA-PC application will only support National Instrument GPIB device drivers. For a list of the supported NI GPIB cards see Chapter 10.

Remote operation of the LBA-PC can be a simple operation or very complex, depending upon the magnitude of the remote control task. Spiricon’s Service Department will supply some limited free technical support, but must charge for support that becomes more than basic question and answer queries. Spiricon’s engineering department can provide full Remote Control applications developed in National Instruments LabVIEW graphical programming language. Contact Spiricon’s service or sales department for information regarding custom LabVIEW virtual instrument development support.

All information regarding LBA-PC remote control is provided in Chapters 9 & 10.

8.2 How to Disable Remote Operation

The LBA-PC remote control capability is contained in the file REMOTE.DLL that is copied to the directory you specified during the LBA-PC installation. The default installation directory is \SPIRICON\LBAPC\. If you do not have a National Instruments GPIB card, or the GPIB device drivers are not loaded, then you will see an error message every time the LBA-PC application is started. To avoid this error message, and disable the LBA-PC remote capability, you must go to the main installation directory and delete the REMOTE.DLL file.

If you later wish to restore remote capability, copy the file REMOTE.DLL from the \SPIRICON\LBAPC\Remote directory on the Spiricon CD to the main installation directory or reinstall the LBA-PC software.
