Padgett Plus Wireless Keypad Specifications
Technical Specifications for Wireless Keypad Model WRS7200
The Padgett Plus is our primary wireless voting keypad for professional audience response. It is a rugged, single-purpose voting device built for reliability, ease of use, and secure participation, and it supports meetings ranging from small assemblies to large conventions. Every keypad talks directly to a Padgett Base Station over a dedicated radio channel, independent of venue Wi-Fi. See the Padgett Plus overview.
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.
- Audible keypad return reminder and “ping” (keypad finder) function. An alarm can also be enabled to sound when a keypad leaves its Base Station’s coverage zone.
RF Technology
- Two-way RF keypad uses eligible license-free / license-exempt frequencies to communicate key presses to the Base Station, receive control information and messages from the Base Station, and acknowledge keypad transmissions.
- Employs 2.4 GHz frequency-hopping spread spectrum (FHSS) transceivers. FHSS offers excellent range, immunity to interference, and signal security, and an integrated Wi-Fi avoidance feature improves performance in high-density wireless environments.
- Patented, proprietary radio protocol that creates a secure communications network between keypads and their associated Base Station, operates reliably in the presence of other RF devices (WLANs, phones, and similar), and uses integrated error checking to distinguish system signals from all other RF traffic for data accuracy and security.
- 31 channel identities are available to provide installation flexibility and system expandability.
- Internal antenna is protected by the keypad enclosure.
Range
- Power output is selectable by software. Designed to operate in an indoor area up to 650 ft x 650 ft (200 m x 200 m).
- A room’s geometry, radio propagation characteristics, and proximity to RF interferers can influence the actual range experienced.
- Elevating the Base Station often results in a performance advantage.
Speed
- Polling rate is 200 keypads per second. Multiple Base Stations may poll simultaneously, permitting collection of up to 15,500 keypads in 3 seconds.
- Time stamping can identify the speed and sequence of each keypad response.
User Identification
- Each keypad has an RF device identity (“address”) between 1 and 500, plus an RF base identifier (“channel”) between 1 and 31. Addresses may be automatically assigned or preset.
- Each keypad also has a unique device serial number. Serial numbers are permanent and set at manufacturing.
- Both address and serial number may be transmitted with each keypad’s response.
- A “log in” function permits secure user registration.
