Re: [foxboro] DNBI Cabling for long Distance

I've installed a couple KVM units. They work pretty well. Some that I've used 
also let you have a local keyboard/monitor/mouse as well as a remote set so 
that you can switch between  one set and the other. This is great if you have 
the control room controls plus a control station near the processing equipment 
that's not necessarily manned all the time. 
 
These KVMs usually run over CAT5 cable. If you are going to run CAT5, you might 
as well use an X-term unless you aren't running 51s or 70s.

        We have one workstation istalled this way.  It is definitely a 
configuration not
        supported by foxboro, but has worked without problems for us.
        
        One other option to consider is to locate the workstation near the DNBI 
and use
        a kvm extender.  High end KVM extenders are available for both PC and 
Sun
        workstations.  Most will support extensions to 1000 feet (although the 
longer
        the extension, the lower the video resolution supported).  If you need 
to extend
        the serial port also to support a GCIO there are a few manufacturers 
who make a
        kvm+serial for Sun (and lots for windows).
