We use the parallel port to send event markers to an EEG system through labview. In the past the parallel port address was standard (378) as it was on the motherboard. Using a newer computer and needed to add a parallel port so have used a PCI Express card. In device manager there are 2 I/O ranges (2018 - 201F) and (2011-2017). We typically have used the outport.vi to achieve this using the address 378. With the new card however that is not the correct address, but using any of those in the range specified in the device manager for the PCI Express card does not work (i.e., no event codes are sent though the parallel port to the EEG computer). We are using LabView 7,1 (yes I know its old - we have 12 but haven't upgraded yet...) and Windows 7. Previous programs using this were labview 7.1 and windows XP.
Any help would be appreciated as the parallel port is a great way for us to communicate with out other lab systems.
