User Identification:
- Each keypad has a unique RF device identity (“address”) between 1-9999
- Each keypad address maybe changed in our software
- The unique address identification is transmitted with each keypad’s response
- Support multiple Base stations at the same time, satisfy for using in a big conference room or many rooms at the same time
User Input:
SVK68
- “Sign-in” key
- “Yes/No/Abstain” 3 voting keys
- 10 numeric keys for single / multiple choice response, button are labeled 1~10, A ~ J
- Entries can be speed scored to identify response sequence during competitive events
- OEM order is acceptable, terms are negotiable
Display:
“Status”, “Sign-in”, “Vote” 3 red lights indicates
-current device and communication state
-users' keypresses state
-confirm users keypresses and indicate when the Base Station accepts the keypad’s inputs
RF technology:
l 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 acknowledge keypad transmissions
l Special wireless two-way communication chip, high sensibility, good selectivity, excellent range
l Data rates up to 76800bps
l Using 16 bits CRC , assure the correct data
l Narrowband communication technology with FEC correct technology, excellent anti-interrupt
l Support up to 32 channels (standard version is 16 channels), automatic switch, immunity to interference, big capability
l 433MHZ radio frequency (standard version), or 915MHZ / 2.4GHz (custom version, terms are negotiable)
l Using SINGDEN-Vote private protocol
-Creates a secure communications network between keypads and their associated base station
-User entries are acknowledged when received by the base station
-High speed wireless communication, dynamic transmitting data mode instead traditional polling
-Keypads channels will be changed automatically when base station channel changes
l Internal antenna is protected by the keypad enclosure
Range:
l SCK68 Series is designed to operate in an indoor area 100 x 100 meters
l A room’s geometry, radio propagation characteristics, and proximity to RF interferers will influence actual range experienced. It is better to put base station in a high level place
Capacity and Extend:
l 800 keypads per Base Station channel identity
l Support 32 sets of system to use at the same time, and not interfere with each other
l Support 25600 keypads to use at the same time at most
Speed:
l Determined by Base Station. See Base Station Model specification
l Data rates up to 76800bps
l Time stamping is available to identify each keypad’s input sequence in group’s response
Power and Power Management
l Built-in 650mAh rechargeable Li-ion battery ( up to 500 charges)
l keypads will be turned off automatically within the set time
l In the full power, keypads support up to 3000 votes or over12 hours continuous
l Indicate low power in keypads, software can test power level
l Software can control to turn off in real time
System configures:
