Hi everyone,
Just for the record (I guess nobody had any issues or information with
this kind of setup):
I got the 4x1 DVI/ADC switcher anyway (at a bargain) and everything works
fine: I can switch between the sb100 and the sb2000 without trouble. The
display is picture-perfect at 1920x1200 with DVI. The only thing that gave
me trouble is that the USB connectors on the Gefen 4x1 switcher are in
fact connected to a generic USB hub. This results in the following
consequences:
++ The type 6 UNIX USB keyboard and Logitech PS2/USB optical mouse can be
shared between both workstations with all original functionnality
retained: Since it's a USB hub, all of the function/compose keys work as
if the keyboard was connected natively to the workstation.
-+ Since the Keyboard and Mouse presented on the USB bus are 'native' and
only presented to the active USB port, you -must- switch the active
display port prior to powering on the SUN workstation if you'd like the
workstation to detect the Keyboard and Mouse. This is quite different from
some other KVM's (such as the Belkin SOHO Omniview) where emulated
Keyboard and Mouse are present at all times on all KVM ports. The Gefen
USB hub technique allows for full functionnality of the SUN Type 6
Keyboard so I'm pretty happy with this.
I was also happy to discover that USB devices appear to be daisy-chainable
without trouble: I connected the mouse and keyboard to the LCD's USB hub,
which I connected to one of the USB inputs on the Gefen switcher ; both
workstations (the sb100 and sb2000) detected these devices without trouble
at boot time even though they were two hubs away.
Cheers,
