To install the TH4800 drivers:


1.  Place the entire TH4800 driver folder into C:\Program Files\National Instruments\LabVIEWx.x\instr.lib where "LabVIEwx.x" refers to the version of LabVIEW that you are using.  

NOTE:  The TH4800 vi's are written in LabVIEW 7.1.  If you are using an earlier version of LabVIEW than 7.1, these vi's will NOT work (you must download the TH4800 IVI drivers and convert them to LabVIEW as instructed elsewhere).  If you are using a version of LabVIEW that is greater than 7.1, you should open LabVIEW and select 'Tools->Advanced->Mass Compile' and then point to the TH4800 directory in order to save the vi's into the correct version of LabVIEW.

2.  Place TH4800.dll into C:\VXIpnp\WinNT\bin

If you do not already have this VXIpnp directory structure, you will need to create it.
