The PRS RF Clickers and RF Receiver add a new dimension to the PRS system—two-way communications. The benefit of the
radio frequency technology behind the Clickers and Receivers is:
•
The
line-of-sight
transmission required by the PRS IR Transmitters and Receivers is not necessary,
•
One RF Receiver can process transmissions from up to 2000 RF Clickers,
•
Two-way transmission makes it possible for PRS to confirm a Response transmission, obviating the need for displaying the
Response Grid, which is essential in the IR-equipped environment to confirm receipt of data transmissions.
The addition of two-way radio frequency transmission to PRS has necessitated some changes to the PRS software, as well as
making a number of new features possible. The
Class
is the focal point of the new RF-based PRS. You will
start
a Class. Student
remote Clickers will
scan
for a Class and
join
it.

Hardware Installation
Your PRS RF Receiver ships with an AC/DC Adaptor Class 2 Power Supply and a 15 foot USB cable.
1
Plug the Power Supply into a wall or power strip outlet.
2
Plug the other end of the Power Supply into the PRS RF Receiver.
3
Plug the square USB B connector into the PRS RF Receiver.
4
Plug the flat USB A connector into an available USB port your computer.
Your RF Receiver does not rely on line-of-sight transmission, so it does not have to be positioned at the front of the room. Just
be aware that it works best when it is
not
sitting on a metal surface (such as your computer box).
Start PRS
When you installed the RF Receiver, Windows
found
it and assigned it to a COM Port. When the PRS software is
started up, it scans the COM ports and makes note of where the RF Receiver has been assigned.
Port Checks
are not
necessary.
Next it scans for Classes. It will compile a list of RF Classes and give you the option of starting one of those RF
Classes.
