Lost Vol UP/DOWN & Mute functions from Logitech Wireless KB through HP Cat5 KVM

I recently updated from an older Compaq 8-Port KVM using discreet Keyboard/Mouse/Video connectors to a new HP 8-Port KVM using the CAT5 cable with RJ-45 connectors and a Interface Adapter on the computer side. I use Compaq EVO workstations running XP Pro Corporate Edition. I also use a Logitech Wireless LX-300 keyboard and mouse and iTouch 222 software. Since changing KVM's, I lost the keyboard button control features for my workstation volume and mute as well as the on-screen volume and mute indications. I have updated to the latest Logitech software and HP firmware on the KVM. Does anybody know how to restore the keyboard control of volume and mute?

You may have a bad ethernet cable. I would try the easy thing first and just go to Best Buy, Amazon etc... and purchase a new RJ45 CAT5 or CAT6 ethernet cable. Since you are receiving an orange light it is indicating that the port is not active. Also check the cable make sure its seated properly at both ends even with a new cable. Cheers! Hope it helps!

Unfortunately, this switch has a dedicated port for keyboard that listens for the keyboard keystroke. You MUST plug the keyboard into the dedicated keyboard port on the KVM switch for the hotkeys to work. I recommend putting the mouse that comes with your keyboard to the side, and using another mouse, plugged into the dedicated mouse USB port on the switch. Not the prettiest solution, but some of those mouse/keyboard combos have some funky hardware!

You Compaq unit is proabably a rebadged Avocent like my HP Analogue KVM. To open the menu on that, you simply press the Print Screen button to open the onscreen menu.

Hope this helps.

KVM Switch 4110 8 port


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?

HP Parts supposedly still stocks the EPROM for this model, so you can try to order it from the HP Parts Store. Check for part 340579-001.

Funny... I was reading about something like this for an HP KVM I' looking at buying... I can't find ANY documentation for that older model. But I did find a forum that gave advisement on how to switch the ports from system to system.

Read this and give it a try:
"Try print screen, then the port number to which you want to switch, then enter.
"

I copied and pasted it into a text file for myself in case it's the correct method for the KVM I'm going to buy here soon. :)

Perhaps the models are similar enough that it'll work.

Please let me know because I am quite curious to see if this will work. I would imagine that there is a universal standard somehow.

I'll be watching.
