I have a 4 port VGA USB/PS2 KVM. Is the 4000 a PS2 product?

no PCs stated ( would be 2 PC or a mix of PC,workstation & servers) none stated, !
no monitor stated, makers name and model and if using VGA ports or not. if now what?
no KVM maker nor model stated. (30 years of makers)++++
no answers possible ever, lacking such key facts.
sorry but KVM's are complex, and 5 generations of them that do not work (backwards or forwards compatibility.)

gens:
PS2 +VGA
USB +VGA
USB +VGA +
then , latter hdmi, +DP + DVI support to now.
vast KVMs exist. and endless sea of KVM exist.

If you are trying to convert your Logitech Trackman Marble FX from PS2 to USB so it will work with Windows 7, you can't just convert the port type - you have to get an "adapter" that converts the PS2 signal to a USB signal. See for ATen - UC 100KMA. WEB SIte:
http://www.aten.com/products/KVM/KVM-Modules-&-Accessories/PS2-to-USB-Adapter~UC100KMA.html#.U5sYrCi4NAE.

It allows you to convert a PS2 keyboard and PS2 mouse/trackball with the one device. It's what I use and it works just fine. The regular $2.00 port adapter was useless.

They are on EBAY sometimes for $20 or so. GOOD LUCK. :)

usb to ps2 converter, the sell them for like 30$ but you can go to radioshack and buy a keyboard for that with the little adapter

Have you tried rebooting once it is connected? Not sure if it makes a difference, but I know you can not hook up PS2 peripherals without rebooting.

so is the KVM (control side, PS2 mouse / kbd>??)
or are all PS2 ports wired to adaptors,? i cant guess this nor what was used before, no history stated.
what was there before, this act?
and what now?
Ill assume worse cases (tossed a coin)
18 (16+2) adapters now. all devices are USB but KVM
ok.?


what mode fails, both the KVM pushbotton switch and or the hot key commands on the kbd?
Oops no manual button as seen on modern KVM.

KVMs are very complex. the hard part is the vast number of different PC.
USB , PS2, VGA, DVI and HDMI.. yah,..
OK 16 +2=18 x ps2, and 9 VGA ports. it is.
NO KVM does it all, ,, old KVM' do NOT work , on new computers, all folks know this , if they tried. or took readings to learn why it fails.
I bet power to the KVM is dead., no LED./
no manual button ,oops.
pin 4 PS2 reads 5vdc and connected up, same?
we use breakout boxes (DIY) to test ports connected.'

that Compaq is very old and no support now, no books.
why not ask at real HP, maybe some old guy there can dig it lost books>
40 KVM? that what you said, really? (or 40/8=5 kvm)?
my guess is the adaptor does not work or power issues
KVM >>PS2>>>ADapt>>> USB.(server) (usb 1,2,or 3 at server?)
The KVM in most cases, here, steals power from PS2 ports but not this KVM , its better.
i'd bet that adaptor cant do that.
(is the caps lock key working on the KBD and laser LED glowing on said mouse?

ask here, real HP.
lets see tests:
1: pin 4 ps2 5vdc?
2: mouse glows?
3: keyboard led , caps lock toggles? (glows)
4: lost the hot key commands (y/n)

one other problem is the BIOS in the server may not like your adaptor at all. When BIOS scans the keyboard. it expects a ID response if missing or grabled, it drops that device port.

btw, one way to cure this, is run headless server software
end KVM for ever.

i run a LAMP server, that comes in the box, no kvm no any thing on ports. it has a web page to go to and do service that way.
port IP+:12321
modern ways work best.
in a server farm, a keyboard/mouse/monitor on rolling cart
for the super sick servers is best...

the other problem is USB only PC or server
does not scan PS2 ports, it has none
so if the adaption fails, at boot time, all is lost.
(BIOS reports connected devices to the OS)(unstated by you)so if the report fails, problems happen
for sure after the boot.

this device is s business device, now ("Enterprise)
the posts on it are like 10 years ago. all links to books now dead.
infact the compaq server that had them is turned off. (grin)
here is my search there. Why not ask them?

I have similar problem. 2 inland KVM's (both have PS2 inputs, one has USB outputs) do not light or recognize my usb mouse with a PS2 adapter. They do recognize a PS2 ball mouse on the KVM's however. One of the computers (Sony vaio 1.5 GHz) does recognize a usb mouse with adapter on 2 other KVM's (Old Belkin and a Trendnet) (the second computer I have not tried in those configurations). Next I will try an optical mouse with a PS2 fitting. That did work with a fifth KVM at an auto business last week.

The MS keyboard & mouse receiver is effectively a USB hub with two devices connected to it. So, plugging it into the keyboard socket on the KVM switch may well work, depending on how that particular switch implements USB. If it just passes things through, it should be OK. On the PC side you should only need to plug in the USB cable from the switch's keyboard port.

This is a common problem with a number of KVM switches - this model in particular. I have heard that the Bytecc BT-2000 connector will work in SOME cases: *5.99 on Newegg - http://www.newegg.com/Product/Product.aspx?Item=N82E16812101117 It might be worth the investment to give it a try, if you haven't already tried this. Bytecc does make very high quality hardware. However, if that doesn't work, there's really not much else that can be done, other than replacing the KVM with one designed to run off a single USB port. Hate giving bad news like that. It's a hardware limitation, I'm afraid.
