Good Morning,
Terminating a SCSI chain is known to be a requirement BUT
understanding the type of termination needed is another story .
This link explaining the actions of a particular multimode Terminator throws
up all sorts of questions !
<http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=11160&item=5127892020>
Can anybody direct me to a description that would provide a better
understanding in laymans terms
of the various types of Terminators , please ?
Basically like most buses it's limited by the lowest common
denominator (ie the slowest/oldest device you've got attached).
Try the wikipedia (a free, on-line encyclopedia)
<http://en.wikipedia.org/wiki/SCSI>
At high enough switching (ie data) rates, wires (ie SCSI cables)
behave like transmission lines. Such lines need to be terminated
correctly to prevent signals being reflected from the end of the
line, resulting in interference and loss of data signal amongst the
resultant noise. Transmission line theory took me about a semester to
understand :)
Have fun,
Shay
