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
