Thinwire/thickwire = does this equal x-length of good 50 ohm coax with
BNCs on either end? If so - thats covered. What I'm *not* doing is
terminating - I didn't figure I'd have to with each connector on the
servers joined by a single run of coax. I have the BNC Ts - should each
end also need 50 Ohms...? Mongo not Grok LAN voodoo...

Subject: DECServer 90L+ startup help
I have a pair (3 actually) of the above terminal servers - I have them
cabled up, yet the two I have connected seem not to play well together...
the remote terminal (a VT220) displays :
>XDS90L-321, Connection Not Established - Network Not Connected
Have you got a proper thinwire segment between all of them? The one thing that always caught my customers out was the end
connections MUST be t-pieces
with 50 ohm terminators, even on the servers. If you've got a DS90 on its
own it must have a t-piece with 2 terminators on its thinwire port,
2 50 Ohm terms per port? Mongo very confused now... Mongo Least
Significant Bit in Error Register of Life....
