Do you know that the RS-485 hardware you’re using could be putting you at risk of data corruption and communication errors?
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-485 driver control methods:
- Application Program Control - under windows environment.
- One-Shot - uses a circuit to activate the enable/deactivate signal.
- Enable Driven When Data Present - hardware approach connecting transmitter data line to transmitter enable pin.
- Automatic Driver Control - software automatically recognizes commands to transmit/disable.
- Automatic Hardware Enable - latest innovation using hardware circuitry on the board to control the RS-485 communications.
