Summary: I won't subtract a star for the length of the cables because i've been dealing with KVM's for years and yet to have found a mfg. to provide cables long enough to meet most peoples needs. With a couple of pieces of velcro to adhere the unit to my desk it is easy to use and functions well with my new G510 keyboard. I had an IOGEAR 4 port kvm but it would not swith via hot-keys and it didn't have hardware buttons so i was screwed.
Summary: This device works well and is a good buy for the money. But, there are two problems. The first is the layout. To make the device more compact, Avocent put connectors on all 4 sides of the enclosure. This makes it really unhandy for mounting. I have glued mine to the top of one of my computer cases and shoved it under the computer table. Which brings up the other problem.
Summary: Works nicely, wasn't expecting much from the audio switching but it's fine. The cables supplied are of an adequate length if you put the unit on top of the computers you're switching between. You may need to get a 63P1 and two 63NW for each computer that need to be further than 1 metre from the unit. The keyboard switch command is scroll-lock scroll-lock [port number] so you don't need to physically press the buttons on the unit.
Excerpt: I got this to replace my DVI KVM, as all my work PCs were replaced with non-DVI laptops. Fast, easy to set up, ans small. 1 cable for KVM, 1 cable for audio (I don't use those). <br /><br />The only thing I don't like about this? The only way to change from PC to PC is hit Scroll Lock (or Numlock) twice to switch to the next PC. With 4 PCs, it takes a while to go from 4 to 3. My last Avocent was Scroll Lock twice, then the PC number to change directly.
Pros: All cables included, Easy To Set Up, Easy To Use, Price
Summary: I bought this to replace a year old cheap 4 port Belkin unit which was touchy from day one, and refused to select the other three inputs, despite being thumped firmly on occasion. It uses special cables which reduces cable mess, but doesn't let you reuse old ones, which is a shame as those supplied (4) are only a metre or so long, and is a stretch for my setup, so the longer Belkin ones have to go in the same pile of disgust as the old kvm.
Summary: Comments about Avocent SwitchView 100 4-Port PS/2 KVM Switch: relatively cheap for it's function, however in comparison with other models I've previously used (switchview 4, etc.) this model lacks a bit in technical and ease. Installation, as with all other devices of this nature require the standard coordination of hook and boot. However, when switching between systems that have different screen resolutions, the port seemingly hangs on a blank screen.
Summary: There's not a big selection of these KVM switches, so if you're stuck with VGA screens these will do the job. I think the PS/2 version is better since switching from one PC to the next happens instantly. The USB version has a delay of up to 30 seconds when you switch between the controllers, this is due to the technology and isn't a fault as such with the product.
