System components
Voting Unit VD30 parliamentary
The VD30 parliamentary voting unit is optimally available with your design and allows single-hand
operation. It has three different digit keys (yes, no and abstain) as well as an ON key switching on
the unit. There is no need switching off the unit because it automatically switches off if not used. It
also has a programmable “*” key for
special use. Voting is immediately
transferred by radio transmission to
the transponder.
The user receives continuous
feedback of his inputs from the backlit
display of the unit and can correct it.
The system also allows the display of
particular command prompts to the
user, thus opening up a new
dimension of interactivity.
The graphical LCD allows display of
both numerical and alphanumerical
characters, readable in the dimmed
conference environment and in direct
sunlight.
The storage and charging case TK50-
DVIII carries 50 VD30 voting units and recharges all of them. Even there the units can respond to
radio communication, can be checked for battery status and e.g. be set all at once to a different
radio channel for the next event, which is much more convenient than doing this individually one by
one.
Transponder / Controller TR30
The transponder TR30 processes all DIGIVOTE
®
III VD30 parliamentary voting units’ responses
and communicates these to the PC software. It handles more than 10,000 handhelds on one single
radio channel. On the 433 MHz ISM band, 5 different channels can be selected to allow separate
systems to operate independently or to increase polling speed by collecting responses in different
channels in parallel. A special RF channel is
reserved for configuration and maintenance
purposes of keypads.
Additionally, the DIGIVOTE® system is largely
immune to radio frequency interference from
WLAN, Bluetooth, mobile phones, etc., in our
days omnipresent in modern conference
environment. The transponder can operate USB
powered in a small classroom environment or
through RS232/485 serial communication, where
long cable runs to the PC control are necessary.
The rugged metal construction allows desktop
operation as well as tripod or rig mounting. An
optional build-in battery prevents data loss in case
of power failures.
