  •  Built-in Li-ion battery, keeping box collects keypad to charge the power together
 
 Characteristics:
Enclosure:
  • Compact case. Rugged ABS plastic construction
             -Styled to fit comfortably in hand
             -Wearable with optional lanyard
  •  Dimensions: 138mm x 46mm x 20mm (L x W x H)
  •  Weight: 100g (net)
  • Color: Black (Other colors available. Cost premium, minimum order quantity, and special terms apply.)
 
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
