Description
The CRS5000 Mini audience response keypads are being used in audience voting systems for interactive meetings, special events, and other feedback activities that the audio-visual industry commonly classifies as ‘ audience response ’, ‘ group response ’, 'audience voting', or ‘ interactive voting ’.
Together CRS5000 wireless audience response keypads and a Reply® base station comprise versatile two-way audience voting systems 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 Reply® (Worldwide) Model CRS940 and Reply® Solo base stations.
- Allows drop-in use with scores of Reply®-compliant software applications.
Technical Specifications
User Identification
- Each audience response 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).
- Each keypad also has a unique device serial number.
- 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:
- 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 audeince response 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.
- Patented and proprietary radio protocol.
- 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
- Reply® Mini is designed to operate in an indoor area 300 x 300 feet. [Note: Other Reply® 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 audience response keypads per Base Station channel identity.
- 15 Base Station channels available.
Speed
- Adjusted by Base Station.
- 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.
Scalability
- Firmware resides in high performance microprocessor chips that can be reprogrammed to facilitate easy upgrade during the life of the product.
- Adding aundience response keypads to an existing system requires them to be set to unused addresses. No change is required on the Base Station when adding audience response keypads of the same channel identity.
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). Call for details.
