Perixx PERIPRO-401 PS2 to USB Adapter for Keyboard and Mouse - Built-in USB Controller - Black

Great response time on my unicomp 104, love that it splits off to two ports for mouse and keyboard.

Works well for me!

Works with IBM Model F (with AT F to PS/2 M) to PC.

I have an antique KVM system attached to several servers. This adapter works perfectly to let a newer machine (with no PS2 ports) to be attached to the system.

I have an old (but high quality) KVM switch that only outputs PS/2. I have a new computer with no PS/2 ports, so I needed to convert PS/2 to USB. I tried 4 converters, and this in the only one that works. It will occasionally repeat a single key on the keyboard (type "e" once, get "eeeeeeeeeeeeeee") but that doesn't happen often and I can live with it. I've used it for 17 days now, and it's been reliable. I also have a Perixx PS/2 mouse, and it's the only PS/2 mouse I've bought in the last few years that works reliably for more than a year. In the future, if I need something and Perixx sells it, I will buy the Perixx.

This device works flawless really impressed. I have an old IBM SK-8840 UltraNav keyboard with the trackpoint and trackpad from a KVM I wanted to use for a travel keyboard for my Thinkpad laptop. I figured the trackpoint would work but wasn't sure how the touchpad would work. Both the trackpoint and trackpad on the keyboard work without issues and I haven't noticed any double typing or missed keys. Device seems well built, wiring seems quality and looks like it should hold up.

I have an old Compaq computer keyboard that is rugged and built to last--and the key characters haven't worn away like several new and inexpensive keyboards. Unfortunately, it has no USB output nor wireless connection for new computers lacking PS/2 ports. But, today a good quality keyboard like this one sells for $150 or more--that is, if you want one built to withstand heavy use over the years. This low-cost adapter actually has the conversion circuits built in to accept old PS/2 keyboard and mouse inputs, and gives a new life to a quality keyboard that has withstood the test of time. So, if you have a quality PS/2 keyboard that deserves to be used with a modern computer, and you don't mind the wired connection, this live-circuit PS/2-to-USB adapter fills the bill--and allows the operation of the CAPs-lock, numbers-lock and scroll-lock LEDs to work as well. Don't settle for an adapter that has no active circuitry to make the conversion. It will likely not work in this application. By the way, I don't use my computer for games so I can't rate this device for gaming. However, I do electronic and print publishing, and this adapter works flawlessly. I have not used the mouse connection as I have a wireless mouse for my daily activities.

Seems well made and a great option for many devices, hence three stars... **BUT** ... the "key" slots - those plastic tabs in PS/2 jacks that stop you from plugging them in the wrong way and damaging the pins - are a bit smaller on this adapter than on original PS/2 ports. For many (maybe most?) devices, I imagine that's fine, but in the 90's they absolutely did manufacture some jacks to use that full size. If, like me, you have a keyboard or mouse with those wider-key PS/2 jacks, this adapter won't work because they simply can't be plugged in to each other.

fait pour ce qui est prévu

Goede adapter om oudere toetsenborden/muizen met een ps/2 connector aan te sluiten op moderne PC'S.

I have only had the adapter for a few days. I am using it to connect my old favorite keyboard to my brand new desktop computer. So far so good; working perfectly. The adapter seems to be well made so hopefully it will last for many years.

Use this to run my personal ps/2 keyboard from my early pc days. Plug it in and play, no huss no fuss, just straight on keyboard ps/2 port to usb-A connector. Works like a charm.

The second purchase of one of these adapters (the other purchase being a pack of two adapters that I also reviewed) that actually works with a vintage German language IBM Model M keyboard on a USB port under Windows. All Umlauts are supported, the "<", ">" and "|" keys work as well as all function keys. I only tested the keyboard part of this adapter, because I don't need mouse functionality. Tested under Windows 10 and 11. I'm writing this review in the hope I can save someone money on testing out countless of these adapters only to find they don't work. tl, dr Version: Works perfectly with IBM model M Keyboards, in particular German ones! Bereits der zweite Kauf eines dieser PS/2-zu-USB-Adapter, der tatsächlich mit einer klassischen deutschen IBM Model M Tastatur an einem USB-Anschluss unter Windows funktioniert. Alle Umlaute werden unterstützt, die Tasten „<“, „>“ und „|“ funktionieren ebenso wie alle Funktionstasten. Ich habe nur den Tastaturteil dieses Adapters getestet, da ich keine Mausfunktionalität benötige. Getestet unter Windows 10 und 11. Ich schreibe diese Bewertung in der Hoffnung, jemandem das Geld für das Durchtesten unzähliger anderer Adapter zu sparen, nur um dann festzustellen, dass sie nicht funktionieren. ​Fazit: Funktioniert perfekt mit IBM Model M Tastaturen, insbesondere mit den deutschen!
