Reply Wireless Interactive Technology

ReplyŽ Mini
A compact and wearable audience response system that's ideal for events large and small.

The CRS5000 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 CRS5000 wireless audience response keypads and a ReplyŽ 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 ReplyŽ (Worldwide) Model CRS940 and ReplyŽ Solo base stations.
  • Allows drop-in use with scores of ReplyŽ-compliant software applications.

System Configuration

A basic ReplyŽ Mini system consists of...

  • One ReplyŽ Mini Wireless Keypad per participant
  • Either one ReplyŽ (Worldwide) Base Station or one ReplyŽ Solo Handheld Base Station per 250 keypads of the same radio channel in a room, and
  • One copy of value-added application software* [Note: Not required with ReplyŽ Solo.]

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.


  • 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.


  • 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. This message acknowledgment is just one of the many patented features of ReplyŽ systems.
    • Permits ReplyŽ systems 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.


  • ReplyŽ Mini is designed to operate in an indoor area 300 x 300 feet. [Note: Other ReplyŽ 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.


  • 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.


  • Adjusted by Base Station.
    • See Base Station Models CRS940 and CRS941 specifications.
  • 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.


  • Firmware resides in high performance microprocessor chips that can be reprogrammed to facilitate easy upgrade during the life of the product.
  • Adding keypads to an existing system requires them to be set to unused addresses. No change is required on the Base Station when adding 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. 5,379,213; 5,724,357; 6,021,119; 6,665,000; 7,277,671; 7,277,671 B1; 7,599,703 B2; 7,747,261 B2; 7,746,820 B2; Re. 35,449. European Patent No. EP 0 697 773; 1 337 127 B1; 1 427 228 B1; 1 478 099 B1. Other U.S. and foreign patents and patents pending.
