Enclosure
- Each wireless keypad is housed in a lightweight, compact, gray
A.B.S. plastic molded enclosure.
- Dimensions: 6.7" L x 3.1" W x 1.5" H.
- Weight: 6.5 ounces.
User Input
- Soft-touch sealed membrane switch panel with 12 tactile keys.
- Ten keys are numbered 1-10. Additional key markings include
A-E on keys 1-5, and “Yes” and “No” on keys 1-2. “Clear” and
user defined “asterisk” keys provide additional functions.
- Optional: Membranes can be
customized to “personalize” the product. Graphics can be
modified. Keys may be changed and/or relocated on the
membrane. Minimum order quantity and special terms apply.
Display
- Seven-segment LED is extremely visible, even in reduced
lighting conditions.
- Validates user input plus shows when the Base Station has
accepted the response.
Power and Power Management
- Powered by a 9-volt battery and internally regulated to 5
volts for consistent performance throughout the life of the
battery.
- Keypad is using power only when transmitting and acknowledging
an entered response. Low battery is indicated by the rapidly
flashing seven-segment LED display when about 100 responses
are remaining.
- Battery provides sufficient power for 10,000+ responses before
requiring replacement.
User Identification
- Each keypad has a unique radio frequency (RF) address between
1 and 250. Combining this “address” feature with a patented
response verification routine provides additional security.
- Keypads operate independently of each other, and keypad
addresses are programmable. Additionally, keypads may be
password-enabled to protect configuration.
RF Technology
- Proprietary radio communication system provides secure,
barrierfree operation between keypads and their associated
Base Station.
- User entries are acknowledged when received by the Base
Station.
- Integrated error checking ensures accurate communication of
responses and control functions.
- Separate frequencies are used to address/control the keypad
and communicate keypresses to the Base Station.
A 216 - 220 MHz RF keypad receiver processes address/ control
signals from the Base Station’s transmitter.
- This receiver is
dual conversion crystal referenced frequency modulated.
- A 345 - 369 MHz RF keypad transmitter sends keypress
information to the Base Station’s receiver. This transmitter
is frequency synthesized and frequency modulated.
- Eight (8) channels are available to provide flexibility.
- Internal antennas are enclosed and protected by the keypad
housing.
Application Software
- Base Station requires application
software to manage keypad data collection.
- Multiple titles are available to expand the use of the system
from basic electronic polling to delegate voting, group
decision making, market research, classroom learning, game
shows, and other advanced applications.
Range
- The system is designed to provide reliable operation in an
area 200 feet by 200 feet with standard omnidirectional,
quarter-wave whip antennas.
- Note: Range can vary due to a room’s geometry and its RF
propagation characteristics. Performance may be improved by
using the optional auditorium/hall antenna kit. This kit
includes high-gain dipole antennas that replace the standard
antennas.
Speed
- The Base Station scans each keypad in sequence. Scan duration
is 1/100th of a second. Within each brief time slice, the Base
Station is able to simultaneously determine a keypad’s
identification and process its response information.
- This “look, listen, verify” routine is both intelligent and
fast. Polling cycles are adjustable to optimize speed to group
size. For example, a group of 50 keypads can be sampled every
one-half second, whereas an audience of 2,000 per room/site can
be sampled every 3 seconds.
Control
- Utilizes a high performance
microprocessor and external permanent memory for storage of
setup parameters and keypad addresses.
- Firmware is resident in the microprocessor chip, which can be
replaced to facilitate easy upgrade during the life of the
product.
Capacity
- 250 keypads per radio channel.
- 8 radio channels are available to support a maximum of 2,000
keypads per room/site.
- Adding keypads to an existing Base Station requires them to be
set to new, unused addresses. No change is required on the
Base Station when keypads of the same radio channel are added.
Compliance
- FCC Rules and Regulations Part 15 certified.
- IC RSS121 certified.
Covered by Fleetwood U.S. Patent No. 5,093,786, Re. 35,449, and
5,724,357. Other U.S. and foreign patents pending.
System Configuration - A basic Reply® system consists of:
- one CRS1200 Wireless Keypad per participant
- one CRS930 Base Station for every 250 keypads of the same
radio channel in a room, and
one copy of application software.
Optional accessories
(purchased separately) include dipole antennas, base station carrycases and keypad carrycases. Training, technical support,
and similar fee-based services are additional.
