Data Packets – A grouping of data to be sent
Glossary (cont.)
Frequency Hopping Spread Spectrum (FHSS) – Method employed by the MDR210A- 485 module which involves transmitting data over several different channels in a specific channel hopping sequence known by the transmitter and the receiver(s).
Module Addresses – Provides a layer of addressing among modules. Modules with the same Module Addresses can communicate together.
Networks – Provides a layer above Module Addresses for communicating between modules. Each network has a unique hopping sequence that allows modules on the same network to remain synchronized together.
Sensitivity – A measurement specification that describes how weak a signal can be (in dBm) and still be detected by the receiver.
Serial Data – Data that enters the
Start bit – A low UART signal to signify the beginning of an
Stop bit – The last bit in a UART data sequence. The stop bit is high and indicates the end of an
Synchronization – Synchronization is used to ensure that the transmitter and receiver are communicating properly with each other and following the same channel hopping sequence.
Transmission Latency – Time required to send a packet of data. This value is dependent on the number of bytes being sent and the baud rate of the module.
Transmit Mode – Mode of operation in which
