From what I can find, PCI-6110 is a product that we have been making since at least 1999. Often, we make revisions to our hardware's construction due to changes in our suppliers, manufacture, etc. These revisions are functionally identical to each other and use the same drivers. This is explained in this Knowledge base article: http://digital.ni.com/public.nsf/allkb/0CFAD02D8C40D1CE862576900056C489
"Revision L" probably refers to the PCI-9110 version that has part number 184111L-01. I found this on ebay: http://www.ebay.com/itm/National-Instruments-PCI-6110-NI-DAQ-Card-4ch-5MS-sec-Analog-Input-/30083363... Some of our internal documents seem to indicate that this revision was replaced with another revision around 2004.
Unless this device is damaged, it will be functionally the same as the PCI-6110 that we currently sell. It can use our most recent DAQmx driver (DAQmx 9.8) as well as some very old versions of DAQmx (at least as far back as DAQmx 7.3), and our very old traditional DAQ driver. You will need to make sure that whichever version of the driver that you choose will be compatible with your version of LabVIEW, your PCI 6110, and your operating system. You can find this information in the readme files for each version of the driver. This document also describes compatbility of DAQmx with LabVIEW: http://digital.ni.com/public.nsf/allkb/B0D5630C0A50D5C6862578E800459248?OpenDocument
You can download all of our drivers for free at ni.com/drivers. You can also find the readme files next to the download.
