Transponder DIGIVOTE® TR30

The transponder TR30 processes all DIGIVOTEIII VD30 keypad responses and communicates these to the PC software. It handles more than 10,000 keypads on one single radio channel. On the 433 MHz ISM band, 5 different channels can be selected to allow separate systems to operate indipendently 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.

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 rigg mounting. An optional build-in battery prevents data loss in case of power failures.
