Technical Specifications

Remote Enclosure

• Each wireless remote is housed in a lightweight, compact, plastic molded enclosure.
• Dimensions: 5.50" L x 2.60" W x 1.20" H.
• Weight: 5.7 ounces.
• User Input - Keypad with 25 tactile keys.
• For numeric response: Ten keys are numbered 1-10, One key is “-“ (dash, negative), One key is “. / “ (dot, decimal & slash, divisor)
• For multiple choice responses: Five keys are marked A-E
• For True / False responses: Two keys are marked T and F
• For special purposes: One key is marked “?” (question mark)
• For multi-keyed responses: One key is marked “ENTER”
• For variable “soft” functions: Three keys marked “^” are placed just below the LCD panel where prompts appear
• For turning the unit on/off: One key marked “CLEAR ON”. Press ON / Press & Hold OFF.

Display

• Highly readable LCD panel with 5.0 cm x 2.5 cm visible area.
• Resolution 128 x 64 pixels
• This versatile panel prompts users, shows status and allows detailed and individualized feedback to the remote user.

Power & Power Management

• Powered by 2 “AA” 1.5v batteries (disposable or rechargeable)
• Remote is using most power only when transmitting (key press). Very low power consumed during idle periods.
• Quality of signal and Battery status information is automatically provided when remote attaches to Base. This allows users to react easily to low batter indications displayed by ConVA application software.
• Remote automatically turns off after 15 minutes of inactivity. Re-connection to current ConVA session is simple on re-start.
• All remotes automatically turn off when ConVA application is closed (optionally).
• Batteries provided sufficient power for approximately 14,000+ key presses before requiring replacement. (Based on 20 hours of continuous duty at 12 key presses per minute)

User Identification

• Each remote has a unique (all space and time) network identifier (MAC address). This allows remotes to be uniquely assigned to an individual user for all space and time. This is the “book store” scheme when users buy or rent a remote for all campus purposes.
• Each remote can also be identified (mapped) by a simple (integer, 1…32…n) identifier. This is the “ordered set” scheme where users pick a specifically numbered remote (numbered stickers are included in kits) from a set of such remotes before starting a ConVA session. Prepared rosters map that logical remote to a specific user.
• The last scheme is the “random set” scheme. In this case, users randomly choose any remote from a set of remotes and are prompted on their LCD screen to key in their user identifier (numeric, up to 9 characters) that uniquely identifies them via the same identifier in a roster.

RF Technology

• Remote <-> Base communications is RF, operates through typical venue barriers with no line-of-sight between remote and Base required.
• The RF subsystem is based on the ZigBee specification of high level communication protocols using small, low-power digital radios based on the IEEE 802.15.4 standard for wireless personal area networks (WPANs) and for applications that require a low data rate, long battery life, and secure networking.
• The RF subsystem operates in the 2.4 GHz radio frequency band and is compatible (interference free) with WiFi, Bluetooth and other RF networks working in the vicinity.
• Each Base station has a unique (all space and time) network identifier (MAC address). Since remotes can “see” base stations in adjacent venues (RF penetrates walls), each remote is prompted to identify which base station to connect to by entering a short 1-4 digit “Room ID” (Base id). The base station ID is displayed by the ConVA application software running on the USB connected PC.

Range & Capacity

• The system is designed to provide reliable Remote operation in an radius 200 feet from the Base station. Note: Range can vary due to a room’s geometry and its RF propagation characteristics.
• 200 remotes can be associated with one Base station.

Base Station

• Dimensions: 3.50” W x 2.50” D x 1.25” H.
• Weight: 2.9 ounces.
• USB powered through USB Mini-B connector via USB 2.0 A/Mini-B Cable (provided) between computer USB port and Base
