WB update: 1V output

[Len Sabatine]

    There where some DI194s sent out free , they had only 1 working channel
    and required a $15 registration fee to get auth code to turn on all 4 chan.
     Early models won't be happy running duals, newer versions will run dual
     config , says Dataq.
    I "purchased " one recently which has 4 working channels and it records
    all 4 as well. . It's a cool  little serial board  for  low bucks  , IMHO.
