kda50 manual and sdi cables & questions

[Heinz Wolter]

my ebay purchase came in, and I figured out the the addressing, but 
a manual would be be nice -alas couldn't find one on bitsavers - anyone
know where to find one? also, anyone have a couple of sdi cables
kicking around - for sale or trade - I want to try out my sdi drives 
- do I need the bulkheads and an odd number if wires - even if
going directly from controller to drive (say one drive to one port)?
Are terminators required? and online/wp switches/dongles needed?
cheers -h
