Eliminate Risk of Contention and Data Corruption in RS-485 Communications

The EIA RS-485 specification does not stipulate the method for controlling the driver, therefore a number of options have evolved. Some methods have significant risk of data contention and corruption because of the time required for a device to relinquish control of the RS-485 network once communication is complete. This Sealevel white paper evaluates the most common RS-driver control methods.
