OptionFinder® Micro+ Audience Response Wireless Keypads
OptionFinder® Micro+
OptionFinder® Micro+ is a miniaturized version of the popular OptionFinder® G3 keypad.
Description
The all-new OptionFinder® micro+ is a small, highly portable response device at an
exceptional price. It makes interactive events economical for groups of any size. Seasoned
users and savvy newcomers alike will benefit from the micro+’s
valuable feature set:
Powerful abilities:
Participants can provide multiple choice and single or multi-digit numeric input. They will also
be able to link to different meetings with a simple keypad feature. Your staff and users will
appreciate the intuitive design and will have fewer questions.
Proven performance:
The micro+ uses patented Frequency Hopping Spread Spectrum (FHSS) technology for
secure and reliable communications. The keypad LED display lets participants know their
input has been counted.
Class-leading TCO:
Low acquisition costs and durable, proven manufacturing standards will enhance your bottom
line. The molded case is resistant to damage and breakage and the circuitry is designed for
long-term reliability. The small size of the micro+ also minimizes shipping and storage costs.
Whether you’re looking to expand your interactive options with a new response keypad or to
try a response system for the first time, the all-new OptionFinder®
micro+ is ready to provide great value and ease-of-use.
Technical Specifications
User Identification
The Link key allows each keypad to easily identify itself and change its channel via dynamic
addressing to communicate with any session or meeting. Users can easily participate in
multiple sessions or activities without the need for manual rostering or attendance verifi
cation. Each keypad has an RF device identity (“address”) between 1-500 and a channel
identity between 1-31. Addresses can be changed with the optional Director portable
programmer.Each keypad has a unique device serial number which is permanent and is
transmitted with every response.
Enclosure
Compact, ultra-durable molded ABS plastic case. Dimensions: 3.0” L x 1.5” W x 0.4” H.
Weight: less than 1 ounce with battery installed.
User Input
14 buttons for entering simple or multidigit responses. Numbers (0-9) plus special keys for
Decimal Point, Alert, Link and Send.
Display
Green and red LED lights confirm presses and successful transmission to the receiver.
RF Technology
Employs specially designed 2.4 GHz frequency hopping spread spectrum (FHSS) transceivers
for excellent range, immunity to interference, and security. Patented and proprietary radio
protocol. Creates a secure communications network between keypads and their associated
receiver. User entries are acknowledged when received by the receiver (patented feature).
Operates reliably in the presence of other RF devices (WLANs, PDAs, phones, etc.).
Integrated error checking discriminates system signals from all other RF traffic, including WiFi,
to ensure data accuracy and to enhance security. Internal antenna is protected by the keypad
enclosure.
Range
Spread spectrum technology is designed to operate in an indoor area 300 x 300 feet
(90 x 90 meters). A room’s geometry and RF propagation characteristics will influence
the actual range experienced.
Capacity
500 keypads per receiver channel and 31 channels available for 15,500 keypads per
room/site, and up to 37,500 per room/site are possible in optional arena mode with 75
channels. 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 simply assigning them to a receiver channel and an available address (can
be completed automatically or manually).
Speed
Default speed is 200 keypads per second. Polling rates are adjustable and can achieve
½-second speed in groups of 100 or less.
Power and Power Management
Powered by one replaceable lithium cell battery. Energy-intelligent keypad powers down after
each response to conserve battery life. Battery life is ~20,000 responses or battery shelf life,
whichever comes fi rst. Low battery indicated on display. The keypad can also transmit a low
battery alert to the receiver.
Communications Security
A proprietary response verifi cation 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.
Receivers: OptionFinder® micro+ USB or OptionFinder® G3
Connects to the presenter’s PC through
USB or ethernet ports. Controlled by
OptionPower® software applications.
Dimensions
USB: 3”W x 0.5” H x 0.9” D
G3: 6.25” W x 2.25” H x 5” D
Unit Weight
USB: less than 1 ounce
G3: 9 ounces
Capacity
500 keypads per channel and 31 channels
allows up to 15,500 keypads per room, and
37,500 per room in optional arena mode (75
channels).
Speed
Receiver polling cycles are adjustable to
optimize speed for group size. For example,
a group of 100 keypads can be polled every
one-half second, whereas a group of 37,500
can be polled every 5 seconds via multiple
receivers.
Connections
Attaches to the operator’s PC by USB or
ethernet connection (USB cable included).
Power Source
Powered by computer USB connection with
70-130 mA current draw, or by Power Over
Ethernet (POE) using midspan and power
injector.
