Plugable USB 2.0 Switch for One-Button Swapping of USB Device/Hub Between Two Computers

  • Compact design provides easy one-touch switching of a USB device or hub between two computers
  • Great for sharing a printer, scanner, or other USB device between two computers (one computer has access at a time)
  • LED indicator lights show which connected computer has control of the attached devices
  • Switch works with any USB-enabled computer without drivers--attached devices may require drivers as usual
  • Attach a powered USB hub that is connected to keyboard, mouse, and USB graphics adapter for an all-USB KVM solution

The Plugable USB2-SWITCH2 USB 1.1/2.0 switch is the ideal solution for one-touch switching of access between two computers to a USB-based mouse, printer, scanner, hard drive, or any other attached USB 1.1/2.0 device. Attach a powered USB hub to the USB2-SWITCH2 instead of a single device for switched access to everything connected to the hub.

Features
The USB2-SWITCH2 works without drivers on any USB-enabled computer (Windows, Mac, Linux, etc.). Connect two computers to the switch via the included five-foot USB A/B cables, attach either a single USB device or a USB hub connected to multiple USB devices (cable not included for switch-to-device/hub attachment), and start enjoying the benefits of switched access. Driver installation for the attached devices may be required on the connected computers.

A single button press is all that's required to change control of the attached devices between the connected computers. LED indicator lights show which connected computer has control.

For anyone considering a KVM switch to provide two-computer access to a single keyboard, mouse, and display, the same result is possible with the Plugable USB2-SWITCH2. Just attach the switch to a powered USB hub that's connected to a keyboard, mouse, and USB graphics adapter for an all-USB KVM solution.

The switch can connect USB 1.1/2.0-compliant devices and hubs, but to function in USB 2.0 speed mode, the connected computer and attached device or hub both must comply with the USB 2.0 standard.

What's in the Box
One Plugable USB2-SWITCH2 compact USB 1.1/2.0 switch with two USB-B female ports and one USB-A female port
Two five-foot USB A/B cables for connecting two computers to the switch

Brad B asked Siren, Speaker and Internet question, slightly complicated project....?

Hi Everyone. I have a project and need some info. Basically, right now, I own a building in a rough neighbourhood, I have installed an alarm siren outside the building that is presently connectec via a 12 v adaptor and basic light switch that i can turn on and off to make people scatter. Here is what I want to do, I am not sure how to proceed, if someone can give me a few tips on each topic I would appreciate it, just need to know where to get started. Keep in mind I want to do it as cost effective and basic as possible. I dont mind the extra work . 1- I want to install a basic system with one speaker outside and some sort of microphone inside that I can speak into to also scatter people . Not an intercom really but a loud speaker (that resembles a siren) that I can speak into from the inside when needed) 2- Also, I would like to know if there is a way to control the siren and or speaker system from a remote location via internet. Not sure of equipement needed etc... I appreciate any tips that can get me started. Thanks 2 -

And got the following answer:

The siren can be controlled from internet or a phone by using a dedicated web server. This is a computer, though it can be a very small one. One way to control it is a 'web relay' in the first link below, which is a stand alone unit that connects to the internet. It provides a little web server, allowing you to browse to it and click on th esiren switch. I expect it needs a fixed internet address, so you can operate it from any internet browser, including a cell phone. This would just turn the siren on and off, but could also turn a PA system on/off and activate a device (MP3 player) that broadcasts a pre-recorded message over a public address system as a separate switch. This circuit board needs a housing and a power supply. The first link below also has USB relays and serial port (RS232) relays that can be controlled from a computer, so could achieve the same thing if suitable software is present on the computer. It means a computer with a fixed address on the internet and that is powered on all the time. The second link has devices that send and receive audio over the internet. While it is dubbed IP Intercom, (where IP means internet protocol) the sound signal received by the intercom could be taken to an external public address amplifier and loud speaker/s. Similarly dedicated software on a PC could receive audio from the internet (a website) and send it to the sound card, where the line out connection then goes to a public address sound system instead of the little speakers near your PC. These IP devices have to connect to your existing internet and share with other stuff on it. This is done using a router. They may need an ethernet connection. Maybe you can find a similar device that can connect to your router using wireless LAN. Maybe there is a LAN in the building already. You can buy PA amplifiers and outdoor speakers easily. It depends how loud you want and how far away it is just what setup to use. I would consider video as well, so you can see and hear what is going on. I think best you find some IT or technical person who can help with getting the boxes and setting them up, and you could wire the loudspeaker etc. A security consultant is the formal way, probably more expensive but in theory more professional. It may not be more expensive in the long run. Solutions that need software to be written are not attractive. Get off the shelf stuff that others have shown to be suitable.

The ethernet controlled relay board work incredibly well with various applications which are distinct to power distribution and protection. The relays include wide adjustment ranges with a scale that is simple to study either in 3 or four digits according to the model. These ethernet controlled relay board aid in growing the flexibility on the applications, minimize the overall power and upkeep costs. You will discover relays which are employed for basic purposes which are available in reputable styles with fast replacement options. And you will discover models that are made use of for industrial applications and heavier duty applications that work on big loads. These solutions are made to meet the lifetime industrial handle needs with the applications.
Their most recent merchandise will be the Time counter, Timer Delay, ethernet controlled relay board, Fast Connect Couplings, Electronic Motor Couplings, Aluminum Couplings, Morse Couplings and many other folks. The web page gives a detailed description of every single model in numerous categories of ethernet controlled relay board couplings and sensors. These goods are incredibly helpful for high-risk applications. The ethernet controlled relay board are also available with capabilities like several timing ranges and functions. The corporation is currently searching for agents and dealers who can market and sell their factory produced merchandise. They may be always on a lookout for building new and much more reliable goods determined by the demands and specifications of the sector.
