Connecting receivers

SMART Response receivers support up to 100 clickers each. You can connect more than one receiver to your computer to support larger classes.


  • Do not connect the receiver to your computer until after you install SMART Response software.

  • For operating safety and to prevent damage to the receiver, connect its USB connector only to a computer that has a USB compliant interface and that bears the USB logo. In addition, the USB source computer must be compliant with CSA/UL/EN 60950 and bear the CE mark and CSA and/or UL mark(s) for CSA/UL 60950.

  • The receiver has a USB 2.0 full-speed peripheral interface that runs at speeds of up to 12 Mbps. The unit works with USB 2.0- and USB 1.1-compliant USB interfaces.

Recommended height for mounting receivers

Unlike infrared devices, SMART Response receivers don’t require an unobstructed line-of-sight transmission path. You can operate SMART Response over longer distances if you minimize interference, signal reflections and the number and size of objects between the receiver and the clickers.

Choose a location for the receiver that’s as high as possible and in plain view of the students’ clickers. For permanent installations, use a USB extender to mount the receiver high on a wall. To minimize interference from other radio-frequency equipment, position the receiver away from other wireless products, such as 2.4 GHz routers and cordless telephones.


To prevent product damage or personal injury, route the USB cable where it will not be stepped on or tripped over.

ClosedTo connect the receiver

  1. Position the receiver in an unobstructed location away from other wireless products, such as 2.4 GHz routers and cordless telephones.

    • For temporary installations, place the receiver on top of your desk.

    • For permanent installations, mount the receiver on a wall or on the front of a piece of furniture using two screws (not provided).

    Orient the receiver with the long side or edge facing the class as shown.

  2. Insert the receiver’s captive USB cable connector into an available USB receptacle on your computer.

    The Ready light on the receiver turns on to indicate that the receiver is receiving power.


    After you connect a receiver, if a message appears asking you to restart your computer, restart your computer.

  3. See Checking receiver status to verify that the receiver is working properly.
