OptionFinder® G2 Audience Response Wireless Keypads
Technical Specifications for Wireless Keypad Model OptionFinder G2
Enclosure
Compact, rugged molded A.B.S. plastic case.
Dimensions: 6” L x 2.5” W x 1” H.
Weight: 5.0 ounces.
Color: OptionFinder Blue
User Input
15 keys for entering multiple-choice responses. Numbers (1-9, 0) and soft key symbols (1-3
bars).
Display shows user entry plus confirms when the Base Station accepts the keypad's input.
Display
Seven-segment LED is easy to read in all lighting conditions. Display shows user entry plus
confirms when the Base Station accepts the keypad's input.
Display coordinates with numbers (1-10) and soft key symbols (1-3 bars).
Power and Power Management
Powered by two standard AA batteries.
Keypad powers down after each response to conserve battery life.
Battery life is ~10,000 responses or battery shelf life, whichever come first.
Low battery indicated on display. Also, keypad can transmit a warning to Base Station.
User Identification
Each keypad has a RF device identity ("address") between 1-250 plus a channel identity
between 1-15.
Addresses are user programmable. Each keypad has a unique device serial number.
RF Technology
Employs specially designed 2.4 GHz frequency hopping spread spectrum (FHSS) transceivers.
FHSS offers excellent range, immunity to interference and security.
Patented and proprietary radio protocol:
Creates a secure communications network between keypads and their associated Base
Station
User entries are acknowledged when received by the Base Station
Permits G2 systems to operate reliably in the presence of other RF devices (WLANs, PDAs,
phones, etc.). Integrated error checking discriminates system signal from all other RF traffic to
ensure data accuracy and enhance security.
Internal antenna is protected by the keypad enclosure.
Range
Spread spectrum technology is designed to operate in an indoor area 450 x 450 feet (150 x
150 meters). A room’s geometry and RF propagation characteristics will influence actual
range experienced.
Speed
Default speed is 100 keypads per second. Polling rates are adjustable and can achieve ½
second speed in smaller groups (<50).
Communications Security
A proprietary response verification protocol integral to the radio design provides a high
degree of signal security.
Frequency hopping and proprietary data communications are additional deterrents to
clandestine interception.
Scalability
250 keypads per Base Station channel identity. 15 identities available for 3,750 keypads per
room/site.
Arena Configuration: 72 identities for 18,000 keypads per room/site
Firmware resides in high performance microprocessor chips that can be reprogrammed to
facilitate easy upgrade during the life of the product.
Add keypads to an existing system by programming new units to unused addresses.
Compliance and Patents
FCC, IC, CE certified. Call for details regarding these and other regulatory certifications.
U.S. Patent Nos. Re. 35,449; 5,724,357; 6,021,119; 6,665,000. European Patent No. EP 0
697 773. Other U.S. and foreign patents and patents pending.
Warranty
2 Year limited warranty: factory, parts and labor.
Base Station
OptionFinder® G2 940B
Connects to presenter PC through USB port. Controlled by OptionFinder and OptionPower
software applications.
Dimensions: 6.5” W x 2.25” H x 5” D.
Unit Weight: 8 ounces.
Capacity: 250 keypads per channel identity. 15 identities allows 3,750 pads per room.
Arena version: Up to 72 identities allows up to 18,000 keypads per room.
Speed: Base Station polling cycles are adjustable to optimize speed to group size. For
example, a group of 50 keypads can be polled every one-half second, whereas a group of
3,750 can be polled every 2.5 seconds.
Attaches to the operator’s PC by USB connection. (USB cable included).
Power Source: Powered by computer USB connection. Current draw 50mA.
