Technical Specifications for Wireless Keypad Model CRS5200

The Padgett (Worldwide) is a small, sleek, and robust frequency hopping spread spectrum system. Because it operates in the unlicensed 2.4GHz band, it’s available for sale or for rent in the US (FCC certified), Canada (IC certified), and Europe (CE certified) as well as many other international regions/countries.

This popular device allows for 10 separate answer options, and its three programmable soft keys provide audience members the ability to alert presenters to questions or comments. The Worldwide’s easy-to-read display confirms a response has been received.

Technical Specifications

User Identification

  • Each keypad has a RF device identity (“address”) between 1-250 plus 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 are user programmable.
  • 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:
    • Elastomeric (rubber buttons), Stocked Item, Order CRS5200-E.
    • Tactile (membrane keys), Special Order item, Order CRS5200-M.
  • Dimensions: 6 in x 2.5 in x 1 in (152.4 mm x 63.5 mm x 25.4 mm.)
  • Weight: 5 oz (148 grams) with batteries installed.
  • Color: Black. (Other colors available. Cost premium, minimum order quantity, and special terms apply.)

User Input

  • 15 keys. Ten numeric keys for entering multiple choice responses. Three “soft” keys available for special use. “Asterisk” and “Clear” keys provide extra functions.
  • Entries can be “speed scored” to 0.05 second (50 millisecond) resolution to identify group response sequence (“fastest finger”) during competitive events.
  • Soft key functions vary according to keypad design:
    • CRS5200-E: Low / medium / high values are indicated in the display.
    • CRS5200-M: Same as CRS5200-E but can also support custom key designs (i.e., yes / no / abs.)

Display

  • Seven segment LED is easy to read in all lighting conditions.
  • Display shows numbers (1-9, 0) and soft key symbols (1-3 bars in stock configuration.)
  • Display shows user key press plus confirms when the Base Station accepts the keypad’s input.

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 acknowledgments of successful entries.
  • Employs Fleetwood-engineered 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. This message acknowledgment is just one of the many patented features of Padgett systems.
    • Permits Padgett 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.

Range

  • Spread spectrum technology is designed to operate in an indoor area 450 x 450 feet (150 meters x 150 meters.)
  • 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.
    • Stock configuration: Default. 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.
    • Default setting is 100 keypads per second. Polling rates are adjustable and can achieve split second speed in smaller groups (<50.)
    • Time stamping identifies each keypad’s input sequence in group’s response.

Power and Power Management

Power

  • Powered by two standard AA batteries (not included.)
  • Keypad powers down after each response to conserve battery life.
  • Battery life is ~100,000 responses or battery shelf life, whichever comes first.
  • Low battery indicated on display. Also, keypad can transmit a low battery warning to Base Station.

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 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. 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.
