Enclosure

Compact and rugged ABS blend case.
Dimensions: 5.25 in x 2.2 in x 1 in (133.8 mm x 54.5 mm x 26.5 mm).
Weight: 3.1 oz (85 grams) without batteries installed. [Note: Add 1.6 oz (45 grams) for 2 AA cell batteries.]
Color: 3 tone (off-white, light gray, slate). [Note: Custom color combinations are available. Minimum order quantities and special terms apply.]

User Identification

Each of the voting keypads has a RF device identity (“address”) between 1-500 plus a RF base identifier (“channel”) between 1-31.
Addresses may be automatically assigned or preset.
Each of the voting keypads 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.
'Log in' function permits secure user registration.

User Input

19 enamel coated elastomeric keys.
Ten keys numbered 0-9 plus a “SYM” key allow entry of simple or sophisticated responses up to 12 characters in length (ex. -1/2*345.067).
Three ‘soft’ keys coordinate with response options shown in the display. The selections are programmable by software and include several options for simplified voting (e.g., Yes No, True False, Yes Abs No, etc.) “Send”, “Alert”, “Search/Scan”, “Clear”, and “Power” keys provide additional functions.
Entries can be “speed scored” to 0.05 second (50 millisecond) resolution to identify group response sequence (‘fastest finger’) during competitive events.
Audible keypress indicator can be enabled / disabled.

Display

2 line liquid crystal display (LCD) echoes user entries and displays messages from the Base Station. LCD features:
Electroluminescent backlighting.
12 characters per line.
Status icons to indicate battery level, response type, correct/incorrect response, login status, RF link activity, RF signal strength, keypad address #, channel #.

RF Technology

Two-way RF voting keypads use eligible license-free / license-exempt frequencies to:
- Communicate key presses to the Base Station.
- Receive control information and messages from the Base Station.
- Acknowledge keypad transmissions. [Note: Response acknowledgment is one of several advantageous features found in products using patented Reply® technology.]
Employs Fleetwood-engineered 2.4 GHz frequency hopping spread spectrum (FHSS) transceivers.
FHSS offers excellent range, immunity to interference, and signal security.
Integrated Wi-Fi avoidance feature improves performance in high density wireless environments.
Patented and proprietary radio protocol.
- Creates a secure communications network between keypads and their associated Base Station.
- Permits Reply® 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.
31 channel identities are available to provide installation flexibility and system expansibility.
Internal antenna is protected by the keypad enclosure.

Range

Power output is selectable by software. Designed to operate in an indoor area 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

200 voting keypads per second.
- Multiple base stations may poll simultaneously, permitting collection of up to 15,500 voting keypads in 3 seconds.
Time stamping can identify the speed and sequence of the voting keypads response.

Power and Power Management

Powered by two replaceable alkaline AA batteries (not included).
Battery life varies according to use. Estimate replacement after approx. 150 hours of continuous operation.
Battery level is indicated on LCD. Also, voting keypads transmit battery level to the 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.
Alarm can be enabled to sound when voting keypads leave their Base Station’s coverage zone.

Scalability

Firmware resides in high performance microprocessor chips that can be reprogrammed to facilitate easy upgrade during the life of the product.
Adding voting keypads to an existing audience voting system only requires them to be set to the channel identity of a Base Station and assigned an available address by either automatic or manual setting.

Compliance and Patents
