Page 3 - Description

3 Description The MDR210A-485 uses an embedded 100-milliwatt, frequency-hopping wireless modem that provides communication between a local RS485 network and a remote network of RS485 connected devices. The MDR210A-485 will automatically sense the direction of data flow and switch the RS485 and Radio...

9 Figure 2a – Generation of Data Packets Data Validity (Cont.) To verify data integrity, a 16-bit cyclic redundancy check (CRC) is computed for the transmitted data and attached to the end of each data packet before transmission. The receiver will then compute the CRC on all incoming data. Any recei...

Page 11 - Why does Sensitivity Matter?

11 Application Notes Why does Sensitivity Matter? Receiver sensitivity is the lowest power level at which the receiver can detect a wave and demodulate data. Sensitivity is purely a receiver specification and is independent of the transmitter. As the wave propagates away from the transmitter, it att...
