I have not used it  but since it is used with the EXB-210 only......

Here is a link to the EXB-210 and EXB-220 8mm libraries (check out chapter 5)

        Hello everyone...I'm curious about a robtest command that has
been there as far back as I can remember (version 1.6).
         
        Once you are in robtest the command is "initrange"
         
        How many of you use initrange?  And if you do use it what do you
use it for?  
         
        Any Symantec (Veritas) input is welcomed as well.
         
        Thanks very much,
        David
