Manual for the Protec Bytelan KVM/4

Does anyone have a pdf of the Protec Bytelan KVM switch. I inherited one after our server room was consolidated with another. But the KVM did not have a power source nor a manual. It was originally on a number of unix systems, and the SW switches on the back configure the usage of the keyboard / mouse and right now, I've got the power running and video is ok, but the mouse and keyboards are not working. I assume the SW switches on the back are the issue. Thanks, Steve exsfcp

Re: Manual for the Protec Bytelan KVM/4

The switches are used when cascading more than a single BYTELAN KVM. It specifies the scan rate, and which KVM unit the keyboard and mouse are connected to. For a single KVM, use the default settings. SW1 SW2 Scan Rate ---------------------- ON ON 2 seconds OFF ON 10 seconds ON OFF 20 seconds OFF OFF 40 seconds SW3 NOT USED SW4 ON For KVM unit with KB/mouse OFF For other KVM units w/o KB/mouse, If your power supply isn't adequate, it may cause your KB/mouse problem. It should be 9VDC with at least 500ma. Hope this helps.

We have just installed 2 x new HP KVM switches (main port 16 connects to A port on secondary switch) with HP TFT7600 rack mount monitor and keyboard. Issue is we cannot connect to Servers on secondary...

Try swapping the switches over, your second switch box may be faulty.

You could also check the ips to make sure u have no conflicts.

AP5201 KVM was working; after power down, moving rack, setting up again -- no keyboard action. Got the right plugs in the right ports. Powered down as the manual says and powered back up. Tried different...

If other keyboards and mice won't work, it sounds like your KVM bought the farm. Does it have any power lights that come on? is it plugged into a live outlet? Are they PS2 ports or USB? PS2 ports don't like power surges. Is the device plugged into a UPS? Does the UPS have power or is is tripped? In a server room?

Users manual for KVM model ''MT-471s Auto KVM''

turns out if I double tap and hold the scroll lock key, the kvm rapid beeps and while in this mode, I can hit the numbers 1 to 4 to pick the port I want to connect to.

The double tap on the scroll lock suggestion was sent to me by a fixYa responder. Thanks,

Hotkey Not working?

I've been scratching my head, trying to remember the sequence for the past couple of years. Today I finally worked it out:

1. Press and release Ctrl-Alt-Shift simultaneously.

2. Press and release the digit corresponding to the machine you want (1--4).

3. Press and release the Enter key.

Compaq 8 Port KVM Switch 147094-001

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.
