The MDR29x transceiver is a Frequency-Hopping Spread Spectrum (FHSS) radio designed for license-free
operation in the 900 MHz ISM band. The radio sustains a standard asynchronous serial data stream
between two or more radios out of the box. Housed in a compact and rugged die-cast enclosure, the radio
is equipped to replace miles of serial cable using an RS232, RS485, or USB interface.

The MDR29x uses Frequency Hopping Spread Spectrum modulation, where the units "hop" from frequency
to frequency many times per second using a specific hop pattern applied to all the transceivers in the same
network. A distinct hopping pattern is provided for each Channel Number, thereby allowing multiple
networks to co-exist in the same area without interference.
MDR29x transceivers operate in a Point-to-Point or Point-to-Multipoint, Client-Server architecture. One
transceiver is configured as a Server and there can be one or many Clients. To establish communication
between transceivers, the Server emits a beacon and upon detecting a beacon, RF link is established with
the Client(s).
MDR29x’s implement a proprietary communication protocol to provide secure data transmissions. The use
of FHSS technology ensures data reliability over long distances. Use of license free frequency bands ensure
that the units are ready for use with no further certification requirements.
Each unit is small and easily portable for use in mobile and temporary settings as well as for fixed
installations. The Black Box MDR29x configuration software enables custom configurations based on unique
application requirements.
