OptionFinder® Micro Audience Response Wireless Keypads
OptionFinder® Micro
OptionFinder® Micro is a miniaturized version of the popular OptionFinder® G2 keypad.
Description
OptionFinder® Micro is being used in interactive meetings, special events, and other
feedback activities that the audio-visual industry commonly classifies as ‘ audience response
’, ‘ group response ’, or ‘ interactive voting ’.
Together OptionFinder® Micro wireless audience response keypads and a OptionFinder® G2
base station comprise a versatile two-way interactive voting system that includes these
features:
Slim case with soft touch elastomeric keyboard and LED indicators.
Smaller than a credit card and weighs less than an ounce. Fits easily in the palm and may be
comfortably worn with an optional lanyard.
Two-way spread spectrum radio employing an advanced communications protocol.
Frequency hopping delivers high immunity to interference plus signal security to allow the
system to operate in the presence of other wireless devices.
Works with OptionFinder® G2 and Reply® Solo base stations.
Technical Specifications
User Identification
Each keypad has an RF device identity (“address”) between 1-250 and a channel identity
between either 1-15 (standard version; stocked item) or 1-72 (custom arena version; special
order; special terms and pricing apply).
Addresses may be changed by using an optional WRS960X-T portable programmer.
Each keypad also has a unique device serial number.
Serial numbers are permanent and set during manufacturing.
Both the address and serial number may be transmitted with each keypad’s response.
Enclosure
Compact case. Rugged ABS plastic construction accommodates 2 keyboard designs:
Styled to fit comfortably in hand.
Wearable with optional lanyard.
Dimensions: 3"L x 1.5"W x 0.4"H.
Weight: Less than 1 oz with battery installed.
Color: Black. (Other colors available. Cost premium, minimum order quantity, and special
terms apply.)
User Input
5 elastomeric buttons for entering multiple choice responses. Buttons are labeled 1-5, A-E.
Entries can be “speed scored” to 0.05 second (50 millisecond) resolution to identify group
response sequence (‘fastest finger’) during competitive events.
Display
Green and Red LEDs confirm user keypresses and indicate when the Base Station accepts
the keypad’s inputs.
RF Technology
Two-way RF keypad uses eligible license-free/license-exempt frequencies to communicate
key presses to the Base Station and receive from the Base Station control information and
acknowledgements of successful keypad entries.
Employs Fleetwood-engineered 2.4 GHz frequency hopping spread spectrum (FHSS)
transceivers.
FHSS offers excellent range, immunity to interference, and signal 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. The patented features of
our systems allow them to operate reliably in the presence of other RF devices (WLANs,
PDAs, phones, etc.).
Integrated error checking discriminates system signals from all other RF traffic to ensure data
accuracy and enhance security.
Depending on version, 15-72 channel identities are available to provide installation flexibility
and support up to 3,750-18,000 keypads per room.
Internal antenna is protected by the keypad enclosure.
Range
OptionFinder® Micro is designed to operate in an indoor area 100 x 100 metres. [Note: Other
OptionFinder® products offer greater range. See appropriate specification sheets or contact
us.]
A room’s geometry, radio propagation characteristics, and proximity to RF interferers will
influence actual range experienced. Elevating the base station often results in a performance
advantage.
Capacity
250 keypads per Base Station channel identity.
Standard configuration: Stock. 15 identities available for 3,750 keypads per room/site.
Arena configuration: Non-stock. Special terms and pricing apply. Up to 72 identities for 18,000
users per venue.
Speed
Adjusted by Base Station.
See Base Station Model OptionFinder® G2 specification.
Time stamping identifies each keypad's input sequence in group’s response.
Power and Power Management
Powered by one replaceable lithium coin cell battery (included).
Keypad powers down after each confirmed response transmission to conserve battery life.
Battery life is ~25,000 responses or battery shelf life, whichever comes first.
Low battery indicated on display. Also, keypad can transmit a low battery warning to Base
Station.
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.
