Big Green Button

We can also provide more traditional external panic buttons which complement our Little Green Button software. This optional hardware can be helpful to those users who move away from their PC as the cable allows the Big Green Button to extend away from the computer to provide a reliable alert system even when you’re not at your desk.

DSC_0491The Big Green Button is connected to the PC via the USB port on a length of cable. They come as standard with a 1 metre length of cable but a USB extension cable can be used if a longer length is required. More than one button can be connected to a PC.

How does it work

The Big Green Button lights up to show that it is working, the colour of the light reflects its status in the same way as the Little Green Button software does. When the button is green this shows that it is ready for use and other locations are available to respond.

Requesting Assistance

If you require assistance activate the Big Green Button as per the settings configured within the Little Green Button software on the PC to which this button is connected, for example, press once. The Big Green Button turns red to show that it has been successfully activated:

Green   Red

When the hardware is activated the Little Green Button software works in exactly the same way. So if the Big Green Button shares the same location as the button on the PC to which it has been connected to the on-screen button turns red and alerts are sent to other PCs exactly as if the on-screen panic button had been activated. If the hardware has been configured with a different location name to the PC where it is connected (for example, the hardware has been installed in a nearby room without a PC) an alert will display on this PC also.

If a colleague responds to a panic alert that you have raised with your Big Green Button the light inside will turn yellow briefly (letting you know that help is on the way) before turning green again ready to request assistance again should it be necessary.

Cancelling the request

You can cancel the panic alert if you repeat your method of triggering the alert. The light inside the Big Green Button will return to green.

Adding a new Big Green Button

Plug the Big Green Button into the USB port of the PC you would like to connect it to. Ensure that you are running version Little Green Button v3.3 or higher, the latest version can be downloaded from:

The Big Green Button that you have connected will work automatically without you needing to install any additional software.

The button will light up immediately when plugged in and will remain lit while power is going to the PC. It will behave in the same way as the on-screen Little Green Button, therefore, it will go green when it connects and recognises other buttons available to respond. If there is currently no one available to respond it will revert to a white light.

By default, the Big Green Button will be enabled and ready to use. It will be set to use the same location as the button on the PC.
