DS10 on a KVM

[Marty Kuhrt]

Up until just recently I've been using DS10s with VTs plugged
into the console port. Now I'm trying to hook some up to KVMs
and graphic monitors and not having much luck.

If I hook the keyboard, mouse and monitor up directly, eveything
seems to work fine. If I hook them up through a KVM, I get
mixed results. Sometimes it'll work, sometimes the mouse will
disappear, sometimes the keyboard would lockup, sometimes the
monitor will not sync, etc.

I've tried three different KVMs, two keyboards, and three
different DS10s with the same results. The KVMs were an OmniCube
2 port, a Raritan Master Console IIx 16 port, and a Compaq
120206-001 1X2P KVM. The keyboards tried were LK461-A2 and
LK46W-A2. One with a 4D10T video card, the other two with the
DV-DEPVZ-AA PCI SCSI/NIC/Vid combo card. VMS V7.3, all patches
as of 1-FEB-2002.

So, long story short, what DS10 KVM combo works for you?

I've used the Raritan System Commander with success on DS20's. It's the
one
with push buttons and specifically says for Alpha's. I use the LK461
keyboard.

I use a ServeView+ from Rose Electronics (http://www.rosel.com/). It works
with a variety of Alphas and a LK411-AG. There is one bug, though: after
a reboot you need to connect a real keyboard directly to the KVM-switch, press
a few keys and reconnect the switch. Otherwise the keyboard doesn't work
properly.

I have a PC, an AS255, a DPW500, and a DS20E hooked up to my Omni View
SE switch. All work fine. I have the PC keyboard (a KB-9805) and a
logitech mouse for input.

The Raritan KVMs are the ONLY ones I have gotten to work with Alpha's

A few years ago I purchased a couple of racks with an ES40 and DS20s
fitted with a COMPAQ KVM (1x8) and keyboard tray. After a firmware
upgrade last spring, it works very reliably.

The cheap ones (around $90)

They work fine - we just installed a couple with DS10's running VMS

As long as you use the PC-style keaboard. The tricky thing is a DEC-style
keyboard.

[Fred Kleinsorge]

VMS and Tru64 both run the keyboard in scanset 3 mode, and also program a
few additional settings.

The X WIndows System wants to see all keys go down and all keys go up, the
simplest way to do this on a PS2-style keyboard is to program it into a mode
that sends a single keycode (and up prefix) for each key. The PeeCee runs
the KB in the default mode - in which it does stupid things like generating
different keycodes if say, the shift key is pressed, and generates
multi-byte sequences.

So you have a major problem using a "simple" keyboard switch. When
switching to an Alpha box running VMS or Tru64, you really want to generate
a power up sequence - this will allow the KB driver to determine the type of
keyboard, and program it. When switching to the PeeCee, the KB needs to be
reset, but the power up sequence probably doesn't need to be sent.
