Welcome to the OptoForums! Could you tell us more about your bigger goal -- for example what you want to monitor and/or control using the SNAP-PAC-EB2 brain and what will your "controller using Matlab" do?
There are many options for communicating with a SNAP-PAC-EB2 brain. Which one is best for you could depend on these factors. Is Labview a requirement? Matlab?
One of the easiest ways to control/monitor a SNAP-PAC-EB2 brain is using [PAC Project (the basic version is free). The controller could be either [URL="http://www.opto22.com/site/downloads/dl_drilldown.aspx?aid=3690"]PAC Sim (also free, runs for up to 12 hours) or [URL="http://www.opto22.com/lp/pc_based_controller.aspx"]SoftPAC](http://www.opto22.com/site/downloads/dl_drilldown.aspx?aid=3146) (which is included in PAC Project Pro or could be purchased separately).
Of the methods/linked mentioned previously in this thread, those with "Optomux" in the name wouldn't apply. Also remember that our Product Support is FREE and they'd be happy to help too.
Do tell us more about your project!
