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.
-
Batteryprovides sufficient power for 10,000+ responses before requiring replacement.
|
| |
User Identification
-
Each Fleetwood Reply wireless keypad has a unique radio frequency (RF) address between 1 and 650. 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.
-
Compact radio transceiver (transmitter/receiver combination) processes address/control signals from the Base Station and sends keypress information to the Base Station on 433.92 MHz.
-
Communications to and from the Base Station are crystal referenced. Receiver is SAW referenced superheterodyne design with phase lock detection for superior sensitivity, stability, and selectivity.
-
Internal antenna is 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.
-
Contact your reseller for specifications and pricing of this value added software.

Range
-
The system is designed to provide reliable operation in an area 100 meters by 100 meters.
-
Note: Range can vary due to a room’s geometry and its RF propagation characteristics. Performance may be improved by elevating the base station and/or positioning it in the center of the group
|
| |
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 onehalf second, whereas an audience of 650 per room/site can be sampled every 6 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
-
650 keypads per radio channel.
-
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
-
CE certified (CE 0978). Conforms to R&TTE Directive, Low Voltage Directive, EMC Directive, ETSI EN 300 220-1, and other prevailing EN regulations regarding low power RF devices.
-
Covered by EUropean Patent No. EP 0 697 773. Also covered by U.S. Patent No. 5,724,357 and RE 35,449. Other U.S. and foreign patents pending.
