Purpose of the Keypad

The Reply® DL Model CRS10000 Keypad is a wireless portable device that makes it possible

for a number of people to participate interactively in a class situation or group meeting. The

product accomplishes this by sending keypad switch closure information from the keypad to a

base unit which employs a wireless transceiver to receive the keypad signal. These signals are

processed by the base unit and delivered to a host computer which allows the responses to be

stored, analyzed and if desired displayed on a video projector for feedback to the group

showing the results of their participation. As such, the product is very similar to another

Fleetwood product, the CRS1200. The Model CRS10000 adds to the Model CRS1200 by

incorporating an 800 MHz wireless microphone circuit that allows a participant at a remote

site to speak into the keypad and communicate with an instructor through a phone line

connection. This adds the dimension of allowing verbal interaction from a remote site with an

instructor.

Description of the Keypad

The Reply Model CRS10000 Keypad is housed in a plastic enclosure similar in appearance to

a calculator. It is powered by an internal 9 volt alkaline battery with no external wires or

electrical connections. The keypad uses a membrane switch panel for numeric entry and a 7

segment LED display for entry display to the user. The keypad uses a synthesized transceiver

compliant with FCC Part 15 Subpart B and C. An integrated microphone and talk request

button provide an audio function for use in multiple site applications. The wireless

microphone portion of the device is compliant with and approved under Part 74.

Using the Keypad

To use a Reply® DL Keypad, a corresponding channel Reply® DL base unit must be active

and under control of an application running on a local or remote host computer. This is

usually the responsibility a local facilitator in cooperation with host site staff in a distance

learning environment.

A program on a host site computer under control of the instructor or facilitator determines

when responses from the keypads are to be received and when control of the wireless

microphone in the keypads is required. Typically this program will deliver a number of

informational screens via satellite or other video transmission method on a video projection

system and then will present a question screen. The participants with keypads will then be

instructed to respond using the numeric keys on the keypad. A user holding a keypad responds

by pressing one of the keys and the corresponding number will indicate on the 7 segment LED

display. When interrogated by the base via the 216 MHz link, the keypad sends the key information to the base in a 10 millisecond duration signal from the 345 MHz transmitter. When the 216 MHz signal responds with an appropriate state of the acknowledge bit for the keypad, the keypad turns back off and awaits the next key press. This sequence takes on the average between one and two seconds.
