    an AC adapter saves the most recent setting
    Details for connecting an optional not-sold-by-Monoprice AC adapter.
    This unit can use an AC adapter but it works mostly fine without one. One minor problem with the unit is that if no attached PCs are powered up, then the unit gets no power, and loses its current setting, and defaults back to selecting PC 1. This is inconvenient if you are turning PC 2 or 3 or 4 on and off (say, during some testing), and on each power up, have to manually re-select the target PC.
    An AC adapter solves this problem, by maintaining power even if all attached PCs are off.

    AC adapter specs: The unit has a DC power input jack, 5v, center pin positive, outer ring negative. I measured the current draw, 5v at about 200 mA. (200 milliamps = 1/5 of an amp). DC power jack is size 5.5mm OD, 2.1mm ID (OD = outside diameter, ID = inside diameter, or diameter of the center pin). At Radio Shack, this is DC power jack size "M". (If you want to assemble or make your own)

    However, you can buy an inexpensive AC adapter that fits. Look for an AC adapter for a LeapFrog kids learning toy, either the Leapfrog Clickstart My First Computer, or the Leapfrog Zippity Learning System. These toys use the same AC adapter: 5v, 500mA, 2.5watt or VA, and the DC power plug on these is the right size and polarity.

    You can find them on web or maybe a ToysRUs store for $5 to $15. (Note that there are AC adapters for other Leapfrog units that are the wrong voltage or type, so do not buy them. They won't work, or worse, they might damage your Monoprice KVM.)

    -
    Also, on problems with some keyboards and mice:
    If you are having trouble with a mouse or keyboard, you might try a different age keyboard or mouse that was designed for BOTH PS2 and USB. That is, the interfaces are different and much older keyboards are PS2 only and some newer cheaper keyboards and mice are designed to be USB only, even if you connect with a PS2 adapter. (the USB-PS2 adapter adapts only the wiring and connect pins it does change the signals, voltage, or timing. The internals of the keyboard or mouse still have to be able to process both the PS2 signals and the USB signals to work with both interfaces)
    I don't know if the KVM unit can do all the USB - PS2 conversion if a PC works with one type only, and the keyboard or mouse is the other type only.

    To tell if you have a truly combo keyb or mouse, either look up the specs or details on web for the product item / model number, and see if the specs state that it works with both. Or if the item came with a USB-PS2 adapter, then it was designed to work with both.
    If it is a newer USB only device, it might not work through the KVM to a PS2-only computer, but I have not done any testing so I don't know for sure.

    PROS: Usually works well with mix of PS2 and USB keyboard mouse PCs.

    CONS: Defaults back to PC 1 setting if no power is applied to unit from an attached PC or optional AC adapter.

    Needs external power
    Excellent unit if an external power supply is used. Trouble free.

    PROS: Just to add to my previous review. I still love the unit but I did experience some problems where the monitor and keyboard would go whacky and I would have to press the reset button on the unit (every few days) to get it working again.I fixed this by plugging in an old 5vt power supply from a dead DLink switch. I've never had to reset the unit since (months).

    CONS: Needs external power to be completely stable. External power supply should come with it (although I grant they are cheap and easy to find).

    4/5
    It is hard to complain too much for a $58 KVM with all the available connections. Most of the time the KVM works as it should but occasionally the problems listed in Cons occur. This can be annoying if you are typing a lot but reset fixes everything that I have encountered.

    PROS: Great price for the product. Great for a mix of newer USB devices and legacy PS/2 devices.

    CONS: Periodically engages CAP lock. (Switch to another source and back to fix) Periodically decides to repeat your key press random number of times. Occasionally gets totally confused and needs a reset.
    I wish there was a firmware upgrade to fix these problems.

    Very Pleased
    I bought this unit to switch between two new servers (usb), an old server (ps2), and a security DVR, with the output to an old ps2 rack mini-keyboard with built-in trackball. IT WORKS GREAT, even with this odd-ball assortment of connections.

    The only two improvements I would suggest: Have the "beep" disabled by default. Also, even though there are threaded screw holes for mounting rack ears, no rack ears are provided. You must buy the 8-port version for rack mounting.

    Excellent value
    Bought one if these to connect to to 4 servers. I was expecting a light weight cheap-ish unit but was surprised to find a heavey well built metal enclosure. Im not seeing the continuous mouse movement or keyboard lags that others have reported. This is a tough value to beat. And as usual, MonoPrice rocks.

    Excellent product, work right the way with any USB or PS/2 machine.
    Even those mixed usb, ps/2 system work without any problem at all.
    All machine connected and reboot correctly.

    Best product in class.

    Awesome KVM with one minor flaw
    Purchased this KVM to replace a KVM switch that i've been using in my IT department for the past 5+ years. We needed one that had native USB as our PS/2 to USB adaptor wasn't always working with some computers that did not have PS/2 ports or only had 1 PS/2 port. I was also looking for a KVM that had cables that were long enough for my workstation configuration for cable management, these KVM cables are awesome becasue they are one single cable from tip to tip with the USB and PS/2 branching off the VGA head.

    The only thing that stopped it from being a 10 out of 10 is the placement of the USB and PS/2 ports on the KVM, I wish they were on the sides or on the back to allow better cable managment. Other than that it's a great KVM for an amazing price.

    PROS: Single cable from kvm allows for a super clean installation and cable management, KVm cables are long enough for my application. Very clean look to it, and fast switching. Both PS/2 and USB inputs.

    CONS: USB and PS/2 ports are on the front of the box.

    Great switch
    5/5

    PROS: Just plug and play... can not ask for anything better.... worked perfectly on my win 2003 server & win 7 machine.
    Would recommend to anyone.

    CONS: Cant figure out how to swap using keyboard but I am assuming if I read the directions clearly it would tell me...

    Good quality
    I needed a switch for multiple computers at my desk, so monoprice was my first choice. One thing I like is that it has a feeling almost like medical hardware. The design is very simple and straight-forward. Upon plugging it in, I was pleased to see that it was pretty responsive when switching between multiple PCs. I have a similar switch at work that takes about a second to fully switch over after pushing the button.

    My one con about it is I had trouble getting it to work after one of the PCs was in standby for a while. The other two I had hooked up were turned off, and the "active" one had been in standby for a few days. When I turned it back on, the switch didn't come on, so the mouse and keyboard didn't work. I rebooted the PC, and the switch came back. Hasn't happened since. Not sure what caused it, but it's something to that happened to me that prospective buyers should be aware of.

    PROS: Responsive
    Doesn't need AC power
    Sturdy

    CONS: Can be a little finicky sometimes
